Hi, Chris
I run a tests on a xlp208 board. This kernel is 3.17-rc5. The script are as below. -------------Begin------------------- mkfs.ext3 /dev/mmcblk1p1 mount /dev/mmcblk1p1 /mnt cd /mnt cp -Rf /root/nand_sd_test /mnt cd /mnt/nand_sd_test -------------End---------------------
After several minutes, the following errors will appear. Would you like give me some advice about this error?
Thanks a lot. Zhu Yanjun
