PreArm Check Error : Gyros inconsistent

Hi guys,

I have a Pixhawk from Radiolink and always in every first attempt of armed I get the error “PreArm: Gyro Inconsistent”.

The most strange thing is that i’m using only the external gyro+compass. i disabled the internal to avoid this issue. Also

  • I tried to recalibrate the gyros at least 5 times.

  • I changed the firmware version from the latest to the 3.8.53 because i have a friend with the same board and he does not have issues with this firmware version.

But i have the same behavior

If i disconnect the battery and connect it again on second time the pixhawk arm without any issue.

Wondering if it could be a good solution to disable the INS pre check. Or try disabling SKIP_GYRO_CAL

some help will be very welcome

Thanks in advance

Did you find a solution for this problem? I have similar problem with arducopter:

The problem disappear when I leave the plane with the front to North for some minutes
