SD card issue in embedded linux
My setup: Embedded linux version 3.x on an ARM board with a SD card.
After running for a couple of months, I am getting this print in the console.
I want to understand this issue, and fix it.
Following are the lines thrown by the kernel in console:
mmc0: Timeout waiting for hardware interrupt. mmcblk0: error -110
transferring data, sector 1050656, nr 1, cmd response 0x0, card status
0x0 end_request: I/O error, dev mmcblk0, sector 1050656 FAT-fs
(mmcblk0p2): FAT read failed (blocknr 32)

Sounds like the SD card is dying; is the sector the same number each time? Or within a few hundred? Is it mounted with SD-card-appropriate flags, e.g.noatime? Here's some other suggestions.

Put the sdcard into another computer, and try to save the content with dd into a file, ignoring reading errors. Rewrite the image into a new sdcard and see if it works. command to save: # dd if=/dev/mmcblk0 of=/.file.img conv=noerror,sync
