I am using a Zubax GPS on my rover, cube black, 3.4.2 ChibiOS. External compass is only detected if I boot up the system via USB and switch to on board power after boot. If powered initially with on board battery the compass is not enabled and I of course get compass errors. I have tried several different power modules and all act the same. I have a large hex running the same hardware with 3.6rc8 Chibi and works perfectly. I realize that I’m one of very few using a Zubax UAVCAN on a rover but it is extremely accurate and the rover nails waypoints every time so I’d like to sort this issue out if possible. All worked well with nuttx.
Cheers, RB
