I have a Cube Orange with Arduplane 4.0.9. The SD card installed is the 16 GB card that came with the Cube.
For some reason, dataflash logging isn’t happening. I have tried swapping out the SD card, and I have tried messing with the LOGGER_BACKEND_TYPE parameter (I have tried setting to it 1, 4, and 6). I have tried enabling logging while disarmed. All to no avail.
Board voltage is around 5.2.
What do the three different logger backend types actually mean? I can’t find any online doc that explains the choices. I have been assuming that the block type would be the correct one for writing a .bin file to the SD card, but that’s just a guess. I have no idea what “file” or “MAVlink” backends mean.
What else can I try to get logging to work?
Additional info: At some point a year or so ago, some log files were in fact created – I could see them via the MP “dataflash logs” interface. But attempts to delete them via that interface silently failed. I ended up deleting them manually by plugging the SD card into my computer. But since then, no new logs. But even then, the logs present were quite old, so I don’t think the problem started at that point.
