nand flash 无法分区，是不是nand flash损坏了

Enter your selection: x
doing partition
size = 0
size = 327680
size = 2424832
check bad block
part = 0 end = 327680
part = 1 end = 2424832
part = 2 end = 67108864
2F04000: is bad
k = 0 block = 2861
part0:
        offset = 0
        size = 327680
        bad_block = 0
part1:
        offset = 327680
        size = 2097152
        bad_block = 0
part2:
        offset = 2424832
        size = 64651264
        bad_block = 1
2861

请使用"f"命令，不必理会分区信息，直接烧就行。

这是使用f命令的结果
Enter your selection: f
