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?
