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 _blk_map_tbl_cache_post : read zone tbl err [LOGICCTL_ERR] Switch block mapping table failed when read logical page! Err:0xf _read_block_map_tbl : read data block map table checksum err /********************************************/ ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ... _blk_map_tbl_cache_post : read zone tbl err [LOGICCTL_ERR] Switch block mapping table failed when read logical page! Err:0xfff <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?
