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 <infmt>] [-O <outfmt>] [<input> [<output>]] 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. 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*. <br>_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.
