An IFC NAND problem on the ls1021a board

I meet a NAND read/write problem under u-boot.

My board is booting from NAND but after that I fail to read/write the NAND flash.

While I issue "nand bad", all blocks are displayed.

The result of "nand info" is right:

Device 0: nand0, sector size 512 KiB

  Page size      4096 b

  OOB size        224 b

  Erase size   524288 b

Could anyone show me any ideas?
