[embedded]Boot kernel from tftp server

2017-4-14 萧 写技术

1.Change linux kernel image zImage to zImage.img.

mkimage -n 'nicholas' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008040 -d zImage zImage.img


There is a information head in zImage.img used to recognised by u-boot.


2.Download to RAM of embedded board. I use tftp this time.

Put zImage.img to tftp server dirctory.

Type command in embedded board:

tftpboot 0x30008000 192.168.0.100:zImage.img


3.Boot from RAM.

bootm 30008000
