         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,

KylongMu
