- libusb-1.0 (e.g. on a debian system do a apt-get install libusb-1.0-0-dev)
If not stated otherwise:
The ARM native pieces is not built by default and you need to explicitly name these when running make to have them built (see Makefile). These should be built with an ARM bare metal compiler. Some addititional compiler flags and linker scripts changes is needed to allow using gnueabi compilers.
Prebuilt ARM binaries can be found in bin/
compatibility shortcut to call 'fexc' to decompile a script.bin blob back into '.fex' format used by allwinner's SDK to configure the boards
compatibility shortcut to call 'fexc' to compile '.fex' file into the binary form used by the sun4i kernel
base program of the two aforementioned
Dump information from Allwinner boot files (boot0/boot1)
--type=sd include SD boot info --type=nand include NAND boot info (not implemented)
script interface for talking to the FEL USB handler built in to the CPU. You activate FEL mode by pushing the usboot/recovery button at poweron, by sending the character 2 to boot1, or by booting fel-sdboot from an sdcard.
Simple wrapper around fel-pio and fel to allow GPIO manipulations via FEL
ARM native helper for fel-gpio
A small ARM native SD boot code which forces FEL mode, to make it easier to force FEL mode without having to press the recovery button at power on.
A small ARM native SD boot code which sets PF (CARD0) to JTAG mode and then busy-waits for you to attach with JTAG.
Script for booting via USB (FEL)
gives information about a phoenix SD image created by the phoenixcard utility and optionally extracts the embedded boot code & firmware file from their hidden partitions. Not usable for LiveSuit images.
Manipulatee PIO settings (GPIO / pinmux config).
Can be used both on a file dump of the PIO registers for use by the fel-gpio script or natively on the device by direct mmap hardware acess.
nand-part is a tool to repartition the internal NAND on sunxi devices. It should be (cross-)compiled for the device's architecture, and it requires the device to have a special kernel patch (already included in our kernel tree) to expose the full NAND as a block device.
