Thanks a lot!

Perhaps, this patch will help you:

I tested many export version tag from the U-Boot git tree, it's shows this error message:

U-Boot> cp.b 22000000 c0300000 1024

Copy to Flash... -F- Data Abort detected

With Mr. Andrey's patch, I only modified with common/cmd_mem.c , after this modification, the dataflash

Work OK!

U-Boot > cp.b 22000000 c0300000 1024

Copy to DataFlash... done

So, I hope this patch can be applied to main tree.

Cordially,
