Hi All,
Recently my APM board has not been starting up properly. When I connect it to a serial terminal I can see that it get's stuck on:
Init ArduCopter V2.2
Free RAM: 1343
FW Ver: 113
----------------------------------------
U3þERASING LOGSÒ?
Erasing log...
+
Sometimes there's one + and sometimes two or four. It always hangs at that stage, though. I think something could be wrong with the log memory on the board.
Any ideas? It's stopping me flying and it's beautiful weather today :(
Cheers,
Dave

Dave, please update to the latest software (2.4) and try again.
So I just updated to 2.4 - mistake.
Now my board does nothing except get to the first startup message and then hangs. I tried rolling back to my custom build and it still doesnt work.
Anyone got any protips on dealing with a broken eeprom ? Is it time for a new board? :(
I'm guessing this is on a 2560, as logging is forced to disabled on the 1280 and most don't have an APM2 yet?
Have you tried disabling logging to see if it boots?
in APM_config.h check for this at the end of the file, remove the comment (//) and set it to DISABLED
//# define LOGGING_ENABLED
I should point out this was happening on 2.1 alphas as well. It never happened on the old 49 or 50 versions. I don't know how to roll it back, though.
