更换内核
[scode type="blue"]
- 更新于2021-10-17
我发现最新的5.10内核会导致垃圾路由（比如小米路由3硬改16M flash版）无法正确生成.bin刷机包，取消所有插件以及主题后仍然超出0.19M左右，故尝试更换内核并记录
注释配置文件
内核文件：lede/include/kernel-version.mk
LINUX_VERSION-5.4 = .150
# LINUX_VERSION-5.10 = .70
#注释5.10，启用5.4
LINUX_KERNEL_HASH-5.4.150 = f424a9bbb05007f04c17f96a2e4f041a8001554a9060d2c291606e8a97c62aa2
# LINUX_KERNEL_HASH-5.10.70 = 75736c33711d7f298889ee4981b18774882045323e5c46af9ad3b022082db232
#注释5.10，启用5.4
注释后建议执行
make distclean
# 清除所有相关的东西，包括下载的软件包，配置文件，feed内容等
重新拉取软件包
cd lede/package
git clone https://github.com/kenzok8/openwrt-packages.git
git clone https://github.com/kenzok8/small.git
# 添加插件
cd lede
./scripts/feeds update -a
./scripts/feeds install -a
# 更新插件包

故障内容如下:
- 2.4Ghz 获取IP过慢，且5Ghz无法正常驱动
- 启动过程中黄灯未常亮，而是蓝灯闪烁启动
- 固件网页设置中，无法正常识别到5Ghz无线网卡，且一网卡驱动不上，修改时显示为2.4Ghz无线网卡，怀疑是驱动混乱
