USB OTG Boot

[tllim]

OTG is available on the upper USB port. I used cheap USB-A to USB-A cable
(http://www.amazon.com/gp/product/B000R4L4CM) and it works just fine.

Code:

jjwerner@SantokuVM:~/sunxi-tools$ sudo ./sunxi-fel version
AWUSBFEX soc=00001689(unknown) 00000001 ver=0001 44 08 scratchpad=00017e00 00000000 00000000

This is surprise to me, I thought the OTG should be locate on the lower USB port.

@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

Noted and thanks, looks like I remember wrongly.

So is there any way to boot from USB?
Raspberry pi 3 supports it for some time now: https://www.raspberrypi.org/blog/pi-3-bo...rage-boot/

Please can someone help me identify the "Upper" and "Lower" usb host receptacles?

eg: which is closer to the board?

If I remember correctly from the hardware documentation, the "upper" port is the one farthest from the baseboard.
