Howto remount apalis-t30 linux to check mmc (e2fsck)?

Hi all,
i need help on remounting the root on mmcblk0p2 to check it with e2fsck. does any one has an ideas?
Many thanks for Help.

If it truly requires checking it should automatically do so during regular boot. Alternatively you may use U-Boot’s UMS feature to export the raw block device via USB device connection to a regular Linux workstation for further analysis/checking as outlined e.g. here.
