    Hi.

    I had a similar issue with my 2.6. Check your CLI and messages and look for "no dataflash"

    If you get that message, it would be your 3.3 volt regulator.

      Thanks for infos. I have bad 3.3 vt.regulator ,i,e5.5v and I've changed 3.3 vt reg. IC chip and now it 's fine. i,e 3.3Volts but still couldn't connect to mission planner with this message" no heartbeat received or something like that and yellow LED flashing very fast and steady green light..I might have bad board . I will buy from Hong kong for $45.00 to try it out.
