Hello i'am new one ,I use A20 to design my program I use 2 piece SAMSUNG K9LCG08U0B nandflash and CONFIG_SUNXI_NAND=y . After my kernel running, I mount /dev/nand /mnt it shows many fffff ,and show than:

...
ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  
ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  
ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff

_read_block_map_tbl : read data block map table checksum err

ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff  ffffffff

<4>hfs: unable to find HFS+ superblock                                            
NTFS signature is missing.                                                        
Failed to mount '/dev/nand': Invalid argument                                     
The device '/dev/nand' doesn't seem to have a valid NTFS.                         
Maybe the wrong device is used? Or the whole disk instead of a                    
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? 


who can help me ,very very vey very thanks
