Facing errors related to sd card after a time

Hi,

Could you check what IO voltages the sd card supports?

The nRF7002DK supports 1.8V on the GPIOs, I guess and maybe the sd card uses 3.3V so this can be a problem.

Yes I had 2 cards tried to use both of them

Have you tried using a different sd card, just to rule out the sd card problem?

Actually what happens is sometimes it works very smoothly and sometimes after working for sometimes it suddenly starts giving this timeout related error and failed to open the file

Hi Rakshita,

Could you verify whether your sd card is formatted and working correctly? Maybe verify this by using the sd card in another device.
This is just because the error SDMMC -116 may suggest a sd card issue or that the sd card is not accessed properly.

Hi,

Please take a look at this ticket:

https://devzone.nordicsemi.com/f/nordic-q-a/96568/file-write-gives--5-after-file-size-reaches-cache-size?ReplyFilter=Answers&ReplySortBy=Answers&ReplySortOrder=Descending

The issue could be due to the size as mentioned in the ticket.

Hope this helps.
