[DM8168 Uboot] Using Fatls, then serial port hangs

Haoran Li1

Hi,

   I am using the uboot in DVRRDK 4.0.  I managed to fetch some files via the SD card.  After typing "fatload mmc 0 0x8100000000 flashenv2nand.scr", I find that the uboot cannot get such a find.  Then, I tried to use the "fatls mmc 0" for listing all the files in the BOOT partition of my SD card.  However, it didn't cast what I needed to the terminal.  Instead, some unknown codes are cast as below.

Then, the serial port hangs.  I have to replug the USB2Serial converter; thus I could have my serial terminal revival.

  How can I slove these problem and list my files correctly?  The file I want to transfer from the SD card is absent in this list...

   I am sincerely looking forward to your reply.
