Flashing[edit]
- FEL mode procedure
- Detach all wiring.
- Hold volume and power for about 3 secs. Screen will remain black, but green light should turn on.
- Connecting USB and running lsusb should give you a device with an ID of 1f3a:efe8
- Build sunxi-tools and "$ ./sunxi-fel ver" should return a string like: AWUSBFEX soc=00001625(A13) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
- No obviously exposed UART/JTAG - might be tied to uSD slot
- Entering FEL is part of the boot process (handled by the masked BROM): https://linux-sunxi.org/Boot_Process
- https://linux-sunxi.org/FEL/USBBoot
- The BROM, proper: https://linux-sunxi.org/BROM
- LiveSuit factory flashing software (Linux, OSX, Win) for Allwinner: http://linux-sunxi.org/LiveSuit
- 'PhoenixSuit' (may be Windows only): https://github.com/linux-sunxi/sunxi-livesuite
Bootloader & Onboard Flash[edit]
- A13 is now mainlined on U-boot
- Caveat is that to run completely from the NAND Flash (MTD device), you need some patches
- MTD device driver as well for using the onboard flash directly
- VERY IMPORTANT info over here on how to do that: https://linux-sunxi.org/Installing_to_NAND
- nand-part is used to build the descriptor. Remember to keep partitions for the chain loaders.
Kernel[edit]
- Reusing older sources: https://linux-sunxi.org/Linux_Kernel [most likely not necessary to reuse, because of Mali400 being pretty opensource now]
