Teach you how to burn, write, and write u-boot, kernel, and rootfs (target platform S3C2410)

Kernel partition space:

Creating 4 MTD partitions on "NAND 64mib, 3 V 8-bit ":

0x00000000-0x00080000: "bootloader"

0x00080000-0x00280000: "Linux kernel"

0x00280000-0x00680000: "root file system"

0x00680000-0x04000000: "user space"

Run U-boot:

TFTP 0x30008000 u-boot.bin

Nand erase 0x0 0x80000

Nand write 0x30008000 0x0 0x80000

Run the following command to write the kernel:

TFTP 0x30008000 uimage

Nand erase 0x80000 0x200000

Nand write 0x30008000 0x80000 0x200000

Write a file system:

TFTP 0x30008000 root. cramfs

Nand erase 0x280000 0x400000

Nand write 0x30008000 0x280000 0x400000

[Smdk2410 #] setenv bootcmd NAND read 0x30008000 0x80000 0x200000 \; bootm

Modify root Partition

[Smdk2410 #] setenv bootargs root =/dev/mtdblock2 init =/linuxrc

Console = fig, 115200

[Smdk2410 #] saveenv

Modify TFTP to nandflash

[Smdk2410 #] setenv bootcmd NAND read 0x30008000 0x80000 0x200000 \; bootm

[Smdk2410 #] printenv

Ipaddr = 192.168.1.131

Netmask = 255.255.255.0

Bootfile = "uimage"

Stdin = serial

Stdout = serial

Stderr = serial

Bootcmd = NAND read 0x30008000 0x80000 0x160000; bootm

Environment size: 298/16380 bytes

Erasing Nand... writing to Nand... Done

[Smdk2410 #] Reset

After the restart, the system will enter the transplanted Linux system, and all the burning and writing work will be completed.
