I plugin a USB memory on i.MX257-based board. It is detected and seems to work.
After mount USB to /mnt/usb,I start to test by loop copy a testfile from /mnt/usb folder
to /mnt/usb/temp folder.when the testfile size is over than 1M bytes,I/O error occurs
and it stops working(unmounts itself) after a while.
by the way,the linux kernel version is 2.6.28.
See the attached error log for more information. Appreciate any help to solve this trouble
