I just received a new PocketBeagle and it is really cool.
Tiny and runs our Letux-OS without any line to change. We even can use an existing SD card image from our own Letux Cortex 8 which is almost the same circuitry but bigger.
Incredible how tiny they got it!
Well, there is one line of change in the makesd macro database to support the keyword "pocketbeagle":
http://git.goldelico.com/?p=gta04-makesd.git;a=commit;h=d338b1c8a2d15cbd36b2...
At some time we might introduce a separate U-Boot and device tree file, but for the moment it suffices to
DEV=/dev/sdb ./makesd pocketbeagle
to get a working Debian image where you can ssh root@192.168.0.202 through USB gadget driver.
