Hi, In the Appro IPC DM368IPNC_MT5 USB mounted the flash 2M space, use the command:
insmod g_file_storage.ko file=/dev/sbulla stall=0 removable=1
But in my board, using the USB mount SD card, use the command:
insmod g_file_storage.ko file=/dev/mmcblk0 stall=0 removable=1
Now, there is a problem，Through the computer to read SD card data, the occurrence of the anomaly, the hardware should be no problem. The software uses the Appro program. USB drive to load is in accordance with Appro's.
The problem is:
1, serial print (only when reading data), generally read the 300M file a dozen times, sometimes dozens.

I ask if I want to solve this problem, how to proceed with debugging. Thank you ......
