Hi, 1) Read the FAQ for the definition of stable, snapshots and development. In short, I am running 5.9.
2) My BBB (a Element 14 / Farnell version) seems to boot happily from the mmc card without prompting so I can't provide definite advice here. Personally, I would be holding the button down until I saw the BBB boot from the MMC card. 3) I use kermit (in ports). I have a physical serial port but /dev/U0 would be my guess. set port /dev/ttyU0 set speed 115200 set carrier-watch off set flow-control none c Good luck. Simon.
