[U-Boot] Something wrong about usb driver in u-boot.

[吴滨斌]

Excuse me
 
I am a funs about u-boot.
Something wrong about usb driver in u-boot.
Some files(such as uImage about 7MB) in usb memory can't be readed during u-boot, while the other files(less than 1MB) in this usb memory can be readed successfully.
Many usb memory also have the question.I have try the latest u-boot(2014.7).The problem still appears.
The usb memory is DataTraveler 100 G3 16GB 3.0.
The CPU board is koelsch.
I hope you can get me some help if you have sometime free.
Thank you very much.
The debug Log is follow:
