Thank you Candu1! I was already scratching my head.
What flashing sequence do you get when it is on the bench (no cardboard)?
I did change the startup in rev 0.10. Now the Arduino program looks at 4 things in the same loop: 1) is the radio ok 2) is FMODE LAND 3) have 10 seconds gone by so I can assume the drone has booted and 4) did the drone program.elf finally quit dumping messages to /dev/ttyPA0. The 'offending' condition is signaled with 1, 2, 3, or 4 blinks. If all 4 conditions are met, then it will quit the loop, get a shell started, change baudrate if neccessary and do the thing. Previous versions checked 1, 2 and 3 in one loop and 4 in the next.
