@tom Yes, thanks! That is a good idea. I will do that.
I was looking at the release page of the system image and saw this line with 1.5.3 internal release:
HLOS
Added service file that changes SLPI restart level to avoid board crash when SLPI crashes
What is SLPI and could you describe a little bit more what kind of issues you saw when SLPI crashed?
I also sometimes saw px4io io_reg_get(4,0,15): data error -5 in the logging so maybe that could be related?
