IMU calibration lock

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start in flight-mode or do imu test in test-mode.
2. After adc warm-up the calibration will start. Then it hangs after short 
time. Stays there until reset, serial disconnect etc.

Test bellow shows output in test-mode;

test] imu
Calibrating.<startup_IMU_ground> Warming up ADC...
<startup_IMU_ground> Beginning IMU calibration; do not move plane

code locked after this...

Have not done any code checking but;

Rolled back to 17th dec version.
Same issue. Then i did a setup - reset and reboot.
Then it worked.. Seems that it might have something to do with the settings in 
storage..

Hmm,

After more debugging it seems that its the GPS causing the freeze. One of my 
leads on the GPS unit was almost broken causing some bad connection.

Disconnected the GPS and now everything seems to work ok.

Are you using the 1.0 firmware or the trunk?  Do you have air start enabled?  
Which GPS?

I use the 1.0 firmware downloaded / ie not svn trunk.

I use MTK gps and airstart is disabled.

Currently it is a "feature" of the 1.0 firmware that the ground start will not 
"complete" until gps lock is achieved.  This is intended to prevent users from 
flying till gps lock is achieved.  As a feature this is under review, but at 
present it is the intended behavior.
