MMC/SD card removed unexpectedly



Hello Everyone,

I am facing a strange issue with DM36x where the sd card gets removed unexpectedly. I have video recording module on the system; when the recording is going on the SD card; suddenly the SD card removed events triggered by udev (of-course this comes from kernel). I saw this problem with Sandisk and Kingston 16/32 GB, Class 10 cards. However this issue is random and seen 5-6 times till now in last 25 days.

I read several threads on the internet but none of them gives actual solution; everyone ask to change/format the SD card. I am looking for at-least real root-cause of the problem; if it can not be solved. Due to nature of the product, I can't expect user to go and change the SD card.!

Has anyone experienced such issue?
