On Colibri T20 in situations with frequent unexpected power-cuts, there is a possibility of filesystem getting corrupted.
Could you better describe, what do you want to ask?
rootfs is getting corrupted when unexpected power cuts, i have attached the log.
Yeah, this can happen. The same is also true for the memory storage on your PC. So the solution is to have an emergency power system and detect the power cuts, so you can shutdown the module safely.
