自编译适用于树莓派4B的Openwrt镜像

自编译 Openwrt 镜像

前提准备

1. 查询树莓派的官方固件支持情况。

https://openwrt.org/toh/hwdata/raspberry_pi_foundation/raspberry_pi_foundation_raspberry_pi_4_b

得到CPU型号为 Broadcom BCM2711

2. 下载对应的 `image-builder`

https://downloads.openwrt.org/releases/21.02.1/targets/bcm27xx/bcm2711/

3. 解压压缩包并查看构建帮助

5. 开始构建镜像

考虑到可能是因为驱动问题导致网络不稳定，所以在这里加入了 kmod-rtl8187 kmod-rtl8192c-common kmod-rtl8192cu kmod-rtlwifi kmod-rtlwifi-usb kmod-usb-net-rtl8150 kmod-usb-net-rtl8152 这些内核模块，目前外置USB网卡也稳定运行、效果不错。
