This error message occurs because our IMU driver has noticed a problem with the IMU and has had to reset it. In some cases at least we think this is a hardware problem and all that has changed is that we are alerting the user to the problem.
In any case I’ve added this to the Copter-4.1.0 issues list so hopefully some other devs can look into it once you download a log.
@rmackay9 My messages tab doesn’t mention the imu_reset. Is your statement still accurate?
Thanks for all your help with mine and others.
Yes, I think 0x1000000 is the imu_reset (table of error codes is here in the code). We don’t currently print a human readable string for the internal errors perhaps because we aren’t expecting them to be very common at least in stable releases… we may be wrong though so it’s worth us thinking about improving the message.
