My 3DR APM2.5+ was working fine with 2.91.
So i decided to upgrade to 3.0.1 then the "fun" started.
I was able to upgrade however I had to do the compassmot calibration
Shortly after I could not connect to the apm, it would freeze at the
"Get param" stage 67 out of 296 i think. Connection is via usb. I tried changing
serial port with the same result.
I can load firmwares okay from Mission Planner still. I tried going back to the previous
version with the same reults.
I can also connect via Terminal however when I try to do the
test> imu I get "Failed to boot MPU6000 5 times" then
PANIC: failed to boot MPU6000 5 times.
This is so strange since the apm was working fine before!
Any suggestions ? Thank you
