Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. ## Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. ## TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION **0.** This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. **1.** You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. **2.** You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: **a)** You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. **b)** You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. **c)** If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. **3.** You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: **a)** Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, **b)** Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, **c)** Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. **4.** You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. **5.** You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. **6.** Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. **7.** If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. **8.** If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. **9.** The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. **10.** If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. **NO WARRANTY** **11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. **12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS ## How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. one line to give the program's name and an idea of what it does. Copyright (C) yyyy name of author This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, see . Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands \`show w' and \`show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than \`show w' and \`show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. signature of Moe Ghoul, 1 April 1989 Moe Ghoul, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the [GNU Lesser General Public License](https://www.gnu.org/licenses/lgpl.html) instead of this License. sunxi-tools-1.4.2+git20260530.d7bbd1/Makefile000066400000000000000000000174531521151043200201310ustar00rootroot00000000000000# Copyright (C) 2012 Alejandro Mery # Copyright (C) 2012,2013 Henrik Nordstrom # Copyright (C) 2013 Patrick Wood # Copyright (C) 2013 Pat Wood # # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Command line utilities to work with devices based on [Allwinner SoC]s: sun4i, sun5i, ... - that's why the 'x' in the package name. ### sunxi-fexc `.fex` file (de)compiler Usage: ./sunxi-fexc [-vq] [-I ] [-O ] [ []] infmt: fex, bin (default:fex) outfmt: fex, bin (default:bin) ### bin2fex compatibility shortcut to call `sunxi-fexc` to decompile a _script.bin_ blob back into `.fex` format used by Allwinner's SDK to configure the boards. ### fex2bin compatiblity shortcut to call `sunxi-fexc` to compile a `.fex` file into the binary form used by the legacy 3.4 kernel ("linux-sunxi"). ### sunxi-fel script interface for USB communication with the FEL handler built in to the CPU. You usually activate [FEL mode] by pushing the _uboot_ / _recovery_ button at poweron, or by having your device "fail over" to FEL when no other boot option is available. See http://linux-sunxi.org/FEL/USBBoot for a detailed usage guide. When called with no arguments, _sunxi-fel_ will display a short usage summary. _Note:_ Unless you select a specific device using the `--dev` or `--sid` options, the tool will access the first Allwinner device (in FEL mode) that it finds. You can print a list of all FEL devices currently connected/detected with `./sunxi-fel --list --verbose`. ### fel-gpio Simple wrapper (script) around `sunxi-pio` and `sunxi-fel` to allow GPIO manipulations via FEL ### fel-sdboot ARM native sdcard bootloader forcing the device into FEL mode ### uart0-helloworld-sdboot ARM native sdcard bootloader, which is only printing a short "hello" message to the UART0 serial console. Because it relies on runtime SoC type detection, this single image is bootable on a wide range of Allwinner devices and can be used for testing. Additionally, it may serve as a template/example for developing simple bare metal code (LED blinking and other similar GPIO related things). ### sunxi-pio Manipulate PIO registers/dumps ### sunxi-nand-part Tool for manipulating Allwinner NAND partition tables ### sunxi-nand-image-builder Tool used to create raw NAND images (including boot0 images) ### jtag-loop.sunxi ARM native boot helper to force the SD port into JTAG and then stop, to ease debugging of bootloaders. ### sunxi-bootinfo Dump information from Allwinner boot files (_boot0_ / _boot1_) --type=sd include SD boot info --type=nand include NAND boot info (not implemented) ### phoenix_info gives information about a phoenix image created by the phoenixcard utility and optionally extracts the embedded boot code & firmware file from their hidden partitions. ### sunxi-meminfo Tool for reading DRAM settings from registers. Compiled as a static binary for use on android and other OSes. To build this, get a toolchain and run: make CROSS_COMPILE=arm-linux-gnueabihf- sunxi-meminfo ### sunxi-script_extractor A simple tool, which can be executed on a rooted Android device to dump the _script.bin_ blob from RAM via reading _/dev/mem_. To build this, get a toolchain and run: make CROSS_COMPILE=arm-linux-gnueabihf- sunxi-script_extractor --- ## Building Compilation requires the development version of *libusb-1.0* (include header and library) to be installed for `sunxi-fel`. Unless you explicitly pass *LIBUSB_CFLAGS* and *LIBUSB_LIBS* to the make utility, `pkg-config` is also needed. Development versions of zlib and libfdt are also required. To install the dependencies on Ubuntu 20.04 using package manager: ```bash sudo apt install libusb-1.0-0-dev libz-dev libfdt-dev ``` Available build targets: * `make tools` builds tools that are useful on the host. This is what most people will want, and our default target (when simply using `make`). * `make target-tools` builds tools that are intended for the target (Allwinner SoC), using a cross-compiler. The Makefile will try to auto-detect a suitable toolchain prefix, and falls back to `arm-none-eabi-` otherwise. If needed, you may override this by explicitly setting *CROSS_COMPILE*.
_Hint:_ When compiling 'natively' on the target platform you may simply use an empty toolchain prefix here (`make target-tools CROSS_COMPILE=` or `make all CROSS_COMPILE=`). * `make all` builds both *tools* and *target-tools*. * `make install-tools` builds *tools* and then copies/installs them to a filesystem location. The destination is affected by settings for `DESTDIR`, `PREFIX` and possibly `BINDIR`. For details, please refer to the *Makefile*. You may use `make install` as a shortcut for this. * `make install-target-tools` builds *target-tools* and then copies/installs them to a filesystem location selected by `DESTDIR`, `PREFIX` and possibly `BINDIR` - see `make install-tools` above. * `make install-all` builds and installs both *tools* and *target-tools*. * `make misc` builds miscellaneous (host) utilities that are not part of our 'standard' suite. Currently this means `phoenix_info` and `sunxi-nand-image-builder`. * `make install-misc` builds *misc* and installs the resulting binaries. ## License This software is licensed under the terms of GPLv2+ as defined by the Free Software Foundation, details can be read in the [LICENSE.md](LICENSE.md) file.

This package contains various tools for working with devices based around the Allwinner sunxi processors (A10/A13/A20/A31 etc). Utilities include tools to:

  • interact with the processors' lowlevel bootrom (AKA FEL mode).
  • boot over the USB OTG port.
  • compile and decompile the Allwinner binary hardware descriptions (FEX files).
  • display information about sunxi boot headers.

On explicit request (typically by pressing a button often labeled "uboot" or "recovery"), or when all other booting methods fail, the CPU's early ROM code enters the so called FEL mode, where it will wait for USB commands sent by some host to the Allwinner CPU's USB OTG interface. sunxi-fel implements this FEL protocol and communicates with the ROM code, to download or upload data and to start code execution. Besides simply allowing to write to or to read from device memory, sunxi-fel also helps with more complex things, which involve uploading code, executing it and then returning to FEL mode, to allow further data transfer or inspection. In particular it supports loading and executing U-Boot, including the primary SPL stage. .SH "OPTIONS" Those options affect general execution and should be put first, before any actual commands. .sp .B \-h, \-\-help .RS 4 Print a help message and exit. .RE .sp .B \-v, \-\-verbose .RS 4 Enable verbose logging. .RE .sp .B \-p, \-\-progress .RS 4 "write" transfers show a progress bar. .RE .sp .B \-l, \-\-list .RS 4 Enumerate all (USB) FEL devices and exit. .RE .sp .B \-\-list-socs .RS 4 Print a list of all supported SoCs and exit. .RE .sp .B \-d, \-\-dev bus:devnum .RS 4 Use specific USB bus and device number .RE .sp .B \-\-sid SID .RS 4 Select a device by its SID key (exact match). The SID key of a particular device can be queried using the "sid" command. .RE .SH "SUNXI-FEL COMMANDS" sunxi-fel can take several commands, each followed by their parameters, and will execute them in order. The only exception is the "uboot" command, which will delay launching U-Boot until all other commands have been executed. .sp Please note that accessing any part of the DRAM will not work until the DRAM controller has been initialized. This can be achieved by uploading and executing a suitable U-Boot SPL image, using the "spl" command. Trying to access DRAM before that will most likely hang. .sp Any numbers given as parameters to those commands can be prefixed with "0x" to denote hexadecimal notation or "0" to start an octal number. They are interpretated as decimal numbers otherwise. .PP .B spl .RS 4 Load and execute U-Boot SPL. .sp Upload the given binary file to the appropriate SRAM location, carefully moving the FEL stack out of the way in the process. The binary is then executed. When it returns, the FEL stack is restored and execution is transferred back to the BootROM's FEL routine. .sp If the file additionally contains a main U-Boot binary (u-boot-sunxi-with-spl.bin), this command also transfers that to memory, using the load address stored in the image file, but won't execute it. .RE .PP .B uboot .RS 4 like "spl", but actually starts U-Boot. U-Boot execution will take place when the fel utility exits. This allows combining "uboot" with further "write" commands, to transfer other files possibly needed for the boot. .RE .PP .B hex[dump]
.RS 4 Hexadecimal memory dump. Dumps bytes of the memory region starting at
. The context will be displayed as a hexdump, suitable for human inspection. .RE .PP .B dump
.RS 4 Binary memory dump. Dumps bytes of the memory region starting at
. The context will be dumped "as is" to the standard output, so it can be redirected to a file and processed as binary data. .RE .PP .B exe[cute]
.RS 4 Start executing code at
in memory on the device. .RE .PP .B reset64
.RS 4 Request a warm reset of the core, starting execution in the 64-bit AArch64 execution state, at
. .RE .PP .B wdreset .RS 4 Reset the device by triggering the watchdog with the shortest possible period. This will reset the whole SoC, including all on-SoC peripherals, but might not affect on-board devices like PMICs or PHYs. .RE .PP .B memmove .RS 4 Copy bytes within device memory, from to . .RE .PP .B readl
.RS 4 Read a 32-bit value from device memory at
. The value will be output as a hexadecimal number, prefixed with "0x". The address needs to be 4-byte aligned. .RE .PP .B writel
.RS 4 Write the given 32-bit to device memory at
. .RE .PP .B read
.RS 4 Write memory contents into file. Reads bytes from memory at
and writes the content into . .RE .PP .B write
.RS 4 Store file contents into memory. Writes the entire content of into memory at
. .RE .PP .B write-with-progress .RS 4 Display a textual progress bar while writing to the device. Same as "write" with the "-p" parameter. .RE .PP .B write-with-gauge .RS 4 Same as write, but write the progress in percentages to the standard output. This can be piped to any "dialog" compatible program, when using the --gauge widget. .RE .PP .B write-with-xgauge .RS 4 Same as write-with-gauge, but with extended gauge output. This can be piped to any "dialog" compatible program, using the --gauge widget. Aside from updating the current progress in percents, it also updates the number of bytes written and gives an estimated time to completion. .RE .PP .B multi[write] # ... .RS 4 Like "write-with-progress", but with multiple load adddresses and files, all sharing the same progress bar. .RE .PP .B multi[write]-with-gauge ... .RS 4 Like "write-with-gauge", but with multiple load adddresses and files, all sharing the same progress bar. .RE .PP .B multi[write]-with-xgauge ... .RS 4 Like "write-with-xgauge", but with multiple load adddresses and files, all sharing the same progress bar. .RE .PP .B echo-gauge "some text" .RS 4 Update prompt/caption for gauge output. This outputs a command to be interpreted by "dialog" to change the caption text. .RE .PP .B ver[sion] .RS 4 Show the BROM version. This prints some static data, among other things containing the detected SoC. Can be used to verify a FEL connection is working. .RE .PP .B sid .RS 4 Retrieve and output the 128-bit SID key. This key contains some form of serial number, which should be unique to each chip (although there have been reports of same SIDs for particular batches of chips). .RE .PP .B sid-registers .RS 4 As the "sid" command above, but use the alternative MMIO register access method on the device. There are SoCs that require this method due to bugs in the SID implementation, those known will automatically choose this workaround when using the "sid" command. This command here is to test new SoCs for compliance. .RE .PP .B sid-dump .RS 4 Read the entire SID eFuses array and dump its content. For SoCs with a known eFuses layout, this will annotate the known regions. .RE .PP .B clear
.RS 4 Clear bytes of memory starting at
(filling with zeroes). .RE .PP .B fill
.RS 4 Fills bytes of memory starting at
with the byte . .RE .PP .B spiflash-info .RS 4 Retrieves basic information about a SPI flash chip attached to the SPI0 pins. This is using the same method as the BootROM does, to accesses the same storage that the device could boot from. Prints the manufacturer of the flash chip and its capacity. Should also be used to detect the presence of a SPI flash chip. .RE .PP .B spiflash-read .RS 4 Reads bytes starting from offset of a SPI flash chip, storing the result into . .RE .PP .B spiflash-write .RS 4 Reads and stores its content in the SPI flash, starting at offset . .RE .SH EXAMPLES .RS 4 \fB$\fR sunxi-fel -v -p ver .RE .sp .RS 4 \fB$\fR sunxi-fel uboot u-boot-sunxi-with-spl.bin .RE .sp .RS 4 \fB$\fR sunxi-fel -v -p spl sunxi-spl.bin write 0x44000 bl31.bin write 0x4a000000 u-boot.bin reset64 0x44000 .RE .SH AUTHOR Andre Przywara sunxi-tools-1.4.2+git20260530.d7bbd1/tests/000077500000000000000000000000001521151043200176215ustar00rootroot00000000000000sunxi-tools-1.4.2+git20260530.d7bbd1/tests/Makefile000066400000000000000000000041571521151043200212700ustar00rootroot00000000000000# # tests/Makefile # # Copyright (C) 2016 Bernhard Nortmann # # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The idea is that the resulting binary routines can be transferred to a suitable target device and then executed 'remotely', usually via `sunxi-fel`. Normally you don't need to change or (re)build anything within this folder. Currently our main build process (via the parent directory's _Makefile_) only includes `fel-to-spl-thunk.h` directly. Other _.h_ files are provided **just for reference**. The main purpose of this folder is simply keeping track of _.S_ sources, to help with possible future maintenance of the various code snippets.
