Open ivrj opened 2 weeks ago

ivrj commented 2 weeks ago

Describe the bug

When mag enabled, betaflight is crashing (freezing) on startup. If disable mag, flight controller wont freeze anymore. Mag connected to CL2 DA2 as matek f405 se page orientation. Hardware: Matek f405-se, gps Beitian BE-252Q with magnetometer QMC5883 , Caddix vista Firmware BF 4.5

To Reproduce

wiring hardware as describe on wiring session, enable magnetometer. If disable magnetometer, flight controller will not freeze anymore. Need to put GPS powered on 5v to be able to configure on betaflight configurator, gps only turn on when connect LIPO, otherwise you can't change configuration if powered by USB (4.5v line).
