LS1043A 开发板 OpenWrt 极简复盘笔记

编译与固件提取

  • menuconfig：Target: NXP Layerscape -> Subtarget: ARMv8… -> Profile: SD Card Boot
  • 镜像选择：仅勾选 [*] ext4，其余全取消。
  • LuCI/中文：勾选 luci 与 luci-i18n-base-zh-cn。
  • 提取产物：缓存目录捞出 Image、fsl-nh03-sdk.dtb、root.ext4。

TinyLinux 刷写 eMMC

刷写根系统

  • dd if=/media/openwrt/root.ext4 of=/dev/mmcblk0p2 bs=4M status=progress && sync# 拷贝内核与设备树
  • mkdir -p /mnt/mmc1 && mount /dev/mmcblk0p1 /mnt/mmc1/
  • cp /media/openwrt/Image /media/openwrt/fsl-nh03-sdk.dtb /mnt/mmc1/
  • sync && umount /mnt/mmc1/

U-Boot 固化启动参数

拦截启动进入 U-Boot 执行：

  • setenv bootcmd "mmc dev 0; ext4load mmc 0:1 0xa0000000 Image; ext4load mmc 0:1 0xb0000000 fsl-nh03-sdk.dtb; booti 0xa0000000 - 0xb0000000"
  • setenv bootargs "console=ttyS0,115200 earlycon=uart8250,mmio,0x21c0500 root=/dev/mmcblk0p2 rw rootwait"
  • saveenv && boot

基础网络与 ttyd 配置（主路由模式）

配置 LAN 口静态 IP

  • uci set network.lan.proto='static'
  • uci set network.lan.ipaddr='192.168.2.1'
  • uci set network.lan.netmask='255.255.255.0'
  • uci delete dhcp.lan.ignore # 开启 DHCP
  • uci commit network && uci commit dhcp# ttyd 允许 WAN 口访问
  • uci set ttyd.@ttyd[0].interface=''
  • uci set ttyd.@ttyd[0].listen='0.0.0.0'
  • uci commit ttyd# 重启服务
  • /etc/init.d/network restart && /etc/init.d/ttyd restart

Sing-Box 代理与 TUN 转发

基础运行配置

  • uci set sing-box.main.enabled='1'
  • uci set sing-box.main.user='root'
  • uci commit sing-box# 创建并放行 TUN 接口
  • uci set network.singbox_tun=interface

  • uci set network.singbox_tun.proto='unmanaged'
  • uci add_list firewall.@zone[0].network='singbox_tun'
  • uci set firewall.@zone[0].forward='ACCEPT'# 关闭 DNS 重绑定保护 (对接 5353 转发)
  • uci set dhcp.@dnsmasq[0].rebind_protection='0'# 提交并重启
  • uci commit network && uci commit firewall && uci commit dhcp
  • sysctl -w net.ipv4.conf.all.rp_filter=0

  • /etc/init.d/network restart && /etc/init.d/firewall restart && /etc/init.d/dnsmasq restart && /etc/init.d/sing-box restart

设备树 (DTS/DTB) 互转命令

反编译 DTB -> DTS

  • dtc -I dtb -O dts -o /tmp/myboard.dts /mnt/fsl-nh03-sdk.dtb# 编译 DTS -> DTB
  • dtc -I dts -O dtb -o /mnt/fsl-nh03-sdk.dtb /tmp/myboard.dts
