USB OTG Boot

[Quintus23M]

@tllim,
I can clearly confirm, you have to use the UPPER USB port on the Pine A64+ board to use FEL. To enter FEL mode you have to boot without a SD card inserted.

Once you booted the Pine into FEL mode you can detect it on your host computer

Code:

$ lsusb
Bus 001 Device 017: ID 1f3a:efe8

With the latest patch for sunxi-fel from @ssvb, you can easily upload/download data from the boards memory

Code:

$ sudo sunxi-fel version
AWUSBFEX soc=00001689(A64) 00000001 ver=0001 44 08 scratchpad=00017e00 00000000 00000000
