【昉·星光 2 高性能RISC-V单板计算机体验】在昉·星光2上安装配置新编译的OpenWRT

本文是《【昉·星光 2 高性能RISC-V单板计算机体验】在昉·星光2上编译OpenWRT》的下篇，主要介绍如何基于编好的IMG文件烧入昉·星光 2 高性能RISC-V单板计算机并配置成一台真正可用的OpenWRT。

一、烧写固件

首先执行openwrt-jh71x0-generic-visionfive2-v1.3b-ext4-sdcard.img.gz将压缩文件解压缩成img文件。

root@EliteDesk:~/wigyori/bin/targets/jh71x0/generic$ gunzip openwrt-jh71x0-generic-visionfive2-v1.3b-ext4-sdcard.img.gz
root@EliteDesk:~/wigyori/bin/targets/jh71x0/generic$ ls
config.buildinfo                       openwrt-jh71x0-generic-visionfive2-v1.3b-ext4-sdcard.img  profiles.json
feeds.buildinfo                        openwrt-jh71x0-generic-visionfive2-v1.3b.manifest         sha256sums
openwrt-jh71x0-generic-rootfs.cpio.gz  packages                                                  version.buildinfo

插入tf卡并找到tf卡的设备名，本次设备名是/dev/sdb，如下：

Disk /dev/sdb: 14.86 GiB, 15931539456 bytes, 31116288 sectors
Disk model: SD Card Reader
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 1EAB41CC-D75A-47CC-804D-CEB8295E2A38

Device      Start     End Sectors  Size Type
/dev/sdb1    4096    8191    4096    2M HiFive Unleashed BBL
/dev/sdb2    8192   16383    8192    4M HiFive Unleashed FSBL
/dev/sdb3   16384  221183  204800  100M EFI System
/dev/sdb4  221184 8189918 7968735  3.8G Linux filesystem

最后执行命令sudo dd if=openwrt-jh71x0-generic-visionfive2-v1.3b-ext4-sdcard.img of=/dev/sdb bs=1M oflagirect将img写入tf卡。

root@EliteDesk:~/wigyori/bin/targets/jh71x0/generic$ sudo dd if=openwrt-jh71x0-generic-visionfive2-v1.3b-ext4-sdcard.img of=/dev/sdb bs=1M oflagirect
197+1 records in
197+1 records out
206587685 bytes (207 MB, 197 MiB) copied, 13.3596 s, 15.5 MB/s

二、上电启动

连接好串口线，上电启动。

可以看出，之前编译内核选择的MT7601U驱动已经注册上。

[    7.768106] kmodloader: loading kernel modules from /etc/modules.d/*
[    7.797958] Loading modules backported from Linux version v6.1.24-0-g0102425ac76b
[    7.805455] Backport generated by backports.git v5.15.92-1-44-gd6ea70fafd36
[    8.095998] urngd: v1.0.2 started.

[    9.089881] kmodloader: done loading kernel modules from /etc/modules.d/*

最后熟悉的欢迎界面。

看看系统版本。

三、配置系统

基本思路是把eth1配置成WAN口，eth0配置成LAN口，直接修改/etc/config/network文件成如下内容（其中WAN6可以删除，没啥用途）：

root@OpenWrt:/# cat /etc/config/network

config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd59:7202:60eb::/48'

config device
        option type 'bridge'
        option name 'br-lan'
        list ports 'eth0'

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option ipaddr '192.168.2.1'
        option netmask '255.255.255.0'

config interface 'wan'
        option device 'eth1'
        option proto 'dhcp'

config interface 'wan6'
        option device 'eth1'
        option proto 'dhcpv6'
