内核分区空间:
Creating 4 MTD partitions on "NAND 64MiB 3,3V 8-bit":
0x00000000-0x00080000 : "Bootloader"
0x00080000-0x00280000 : "Linux Kernel"
0x00280000-0x00680000 : "Root File System"
0x00680000-0x04000000 : "User Space"
烧写u-boot:
tftp 0x30008000 u-boot.bin
nand erase 0x0 0x80000
nand write 0x30008000 0x0 0x80000
烧写内核:
