I recently purchased an apm2.8. When I go to read the logs, missionplanner tells me that there is no "dataflash inserted". Is it disabled by default? How do you activate it?
I try to set the variable LOG_BITMASK to 958 and it is impossible. Every time I turn off the apm, LOG_BITMASK reverts to zero.
On the other hand, the external compass gives me erratic values. I calibrated it, put the connector in the right place, removed the jumper... But when I turn the drone around, the compass doesn't move more than a few degrees. Could it be that the compass is damaged?
If someone knows what might be going on and can help me, I'd be grateful.
