Creating 4 MTD partitions on "NAND 256MiB 3,3V 8-bit":
0x000000000000-0x000000060000 : "supervivi"
0x000000060000-0x000000260000 : "Kernel"
0x000000260000-0x000040260000 : "root"
mtd: partition "root" extends beyond the end of device "NAND 256MiB 3,3V 8-bit"
-- size truncated to 0xfda0000
0x000000000000-0x000040000000 : "nand"
mtd: partition "nand" extends beyond the end of device "NAND 256MiB 3,3V 8-bit"
-- size truncated to 0x10000000
看起来内核使用的NAND Flash分区表和你源代码中定义的以及u-boot中使用的并不一样。建议你把u-boot中定义的mtdparts变量加到bootargs里,确保内核和u-boot使用一样的分区表。
