Navio2, Prearm: Logging failed

Hi! I’m using the latest version of emlid software,
Linux navio 4.14.95-emlid-v7+ #1 SMP PREEMPT Mon Feb 4 15:59:56 MSK 2019 armv7l
APM:Copter V3.5.7 (b11c6af3)

currently board suffering “Prearm: Logging failed.” issues. What is the reason?

Logs are really bad. Even with “close while when disarm” option. It either 0 bytes, or it contains params list only.

There are two possibilities:

SDcard log file is corrupted, I had the problem, sometimes with a fresh installation, sometimes after an uncontrolled crash like bad landing and fall on the side…

Clearing the log list (delete the logs from the card) is a solution.

Poor quality of the card. All class10 cards are not equal. I have some good results with Sandisk class10.

I also use the close log after disarm option.
