Hi Randy, thanks for the looking at the log. Yes it is an external compass (Radiolink TS 100 mini that has QMC5883L chip). So the driver was detected correctly I think.
Unfortunately I have no idea of what I could check further, I have two TS100 units, both not working on Chibios. And works not very good on NuttX, having strange peaks I’ve described in Compass stop working but remains healthy
I’ve disabled all the peripheral devices to avoid interferences but that did not solved the issue.
I will also check on v3.5.
