DM8127 IPNC实现本地内核升级



急急急希望通过本地内核文件写到相应的NANDFLASH中实现升级

DM8127,IPNC

1制作ubifs格式文件系统bifs_ipnc.bin,文件系统内包括内核文件uImage,进入文件系统内

2执行/usr/sbin/flash_eraseall /dev/mtd3 指令,擦除/dev/mtd3内核区

3然后执行/usr/sbin/nandwrite -p /dev/mtd3 /uImage 写内核文件uImage到内核区dev/mtd3

4,重启系统,然后出现了以下错误:

loading from Nand0 offset 0x280000

ECC:uncorrectable.

Nand read from offset 0x280000 failed -74

............

............

Verifying checksum .......Bad Data CRC

不能引导内核文件,请教哪里出现了问题!!!
