However, the Pine64 lower USB port is type A and 4 pin which means lacking ID signal. Currently the schematic lets the ID pin float with a pull high resister. In current Pine64 Android OS, we manually set the lower USB port to host mode instead of determine by ID pin. We welcome any suggestion and implementation.
Your "micro cluster" suggestion is interesting, but beyond my knowledge to implement. I can let you borrow 8 SBC when we have more on January to try out :-)
1st it has to be confirmed whether FEL works or not. In case you connect one Pine64 board with a type A/A cable to a linux host and then switch the Pine64 on without SD card... it should be listed on the other machine using lsusb. If it doesn't then FEL is broken.
And for the USB boot scenario I would suspect a more recent u-boot version is needed than the one contained in Allwinner's A64 SDK.
