The SCTLR bits are somewhat different because the V bit is set to 0 on A64 (Low exception vectors, base address 0x00000000) and the UNK bit (Reads of this bit return an UNKNOWN value) is also not the same as on the other SoCs. So the SCTLR check can be relaxed. Changes in v2: - Because the SRAM A and SRAM C reside back-to-back in the address space, it is possible to use 40 KiB of SRAM by the SPL for its code+data+stack. So the FEL backup storage is moved from 0x18000 to 0x1A000 to support this. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com>
sunxi-tools
Copyright (C) 2012 Alejandro Mery amery@geeks.cl
Tools to help hacking Allwinner A10 (aka sun4i) based devices and possibly it's successors, 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 talking to the FEL USB handler built in to the CPU. You activate FEL mode by pushing the uboot / recovery button at poweron. See http://linux-sunxi.org/FEL/USBBoot for a detailed usage guide.
fel-gpio
Simple wrapper (script) around fel-pio and sunxi-fel
to allow GPIO manipulations via FEL
fel-sdboot
ARM native sdcard bootloader forcing the device into FEL mode
fel-pio
ARM native helper (binary) for fel-gpio
sunxi-pio
Manipulate PIO register dumps
sunxi-nand-part
Tool for manipulating Allwinner NAND partition tables
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
