• 環境變數的設定
  

setenv bootargs mem=36M console=ttyS1
root=/dev/nfs rw nfsroot=192.168.42.50:/home/dean/MyTMP/0.18/aspeed/rootfs ip=192.168.42.45:192.168.42.50:192.168.42.1.255.255.0.0:::eth0:off
格式如下:
ip=ipaddr:tftp_serverip:gatewayip:netmask:::網卡名稱:off

Add netconsole parameters as the below:

netconsole=@192.168.42.45/eth0,@192.168.42.46/

The kernel will throw the data of console to the remote pc

Please execute the command in the remote PC and show the console data

netcat -u -l -p 6666 -v

• u-boot之mkimage的使用方式
  

[root@localhost tftpboot]#mkimage -A arm -O linux -T kernel -C none -a 0x30000 -e 0x30008000 -d zImage zImage.img

參數的意義：
-A :set architecture
-O :set OS
-T :set image type
-C :set compression type
-a :set load address
-e :set entry point
-n :set image name
-d :use image data
-x :set XIP (execute in place)
