RAJ.M

Part Number: DM385

Hello,

we are using DM385 custom board. our scenario

we are writing to sdcard continuously in between if we remove the sdcard sometimes sdcard not detached from core (/sys/block/mmcblk0 is present after removing).

For card detect sd-cd (dedicated pin used).

without writing to sdcard if we remove/insert working properly.

Hi Raj,

Which SW release you are using? Can you reproduce this issue on DM38x TI board?

It is recommended not to remove the card while I/O is in progress. You can also use "sync" command before removing SD card.

Regards,
Pavel

Hi pavel,

we are using IPNC 3.5 rdk (kernel 2.6.35)

It is anonymous removal, we need to detect that sdcard status for that same.
