The NAND flash device is mt29f4g08abadawp,
Page size x8: 2112 bytes (2048 + 64 bytes), Main area is 2048B, Spare area is 64B
Block size: 64 pages (128K + 4K bytes)
It can be seen from the above printed information that block_mark_byte_offset = 2018;
First of all, I want to know why the Block Mark appears in the main area?
Then what does the Block Mark indicate? Is it a bad block mark?
Looking forward to your reply, thank!
