Hello Pierre,
currently sometimes the SD/MMC card inserted results in recognition failure on ARM Versatile board:
<<<Plug in MMC card>>>

mmcblk0:<3>mmcblk0: error 3 transferring data
end_request: I/O error, dev mmcblk0, sector 0
Buffer I/O error on device mmcblk0, logical block 0
mmcblk0: error 3 transferring data
