方法一

uboot设置

在ubootline执行以下命令：

• 只要用 双引号 " " → 不管加不加括号，U-Boot 都能解析变量！

• 只要用 单引号 ' ' → 不管加不加括号，U-Boot 全都不解析！

  setenv bootargs "mem=32m console=ttyAMA0,115200 clk_ignore_unused root=ubi0:ubifs rootfstype=ubifs rw ubi.mtd=3 mtdparts=nand:512k(boot),512k(env),4M(kernel),32M(rootfs)"

  设置eth0

  setenv serverip 192.168.18.200
  setenv ethaddr 00:15:00:01:41:27
  setenv ipaddr 192.168.18.100
  setenv netmask 255.255.255.0
  setenv gatewayip 192.168.18.1

  方式一

  setenv bootargs "{bootargs} ip={ipaddr}:{serverip}:{gatewayip}:{netmask}:{board_name}:eth0:off"
  saveenv
  reset

  方式二

  setenv bootargs "mem=32m console=ttyAMA0,115200 clk_ignore_unused root=ubi0:ubifs rootfstype=ubifs rw ubi.mtd=3 mtdparts=nand:512k(boot),512k(env),4M(kernel),32M(rootfs) ip=ipaddr:serverip:gatewayip:netmask:$board_name:eth0:off"
  saveenv
  reset
