# 切换6.1来编译rockchip rk356x设备
1. 执行命令来切换6.1内核`sed -i 's/5.4/6.1/g' ./target/linux/rockchip/Makefile`
2. 删除源码部分文件夹
```bash
rm -rf package/kernel/mac80211 
rm -rf package/kernel/rtl8821cu
rm -rf package/network/services/hostapd
```
3.下载openwrt官网部分文件
```bash
svn export https://github.com/openwrt/openwrt/trunk/package/kernel/mac80211 package/kernel/mac80211
svn export https://github.com/openwrt/openwrt/trunk/package/network/services/hostapd package/network/services/hostapd
```
4. 将在target/linux/rockchip/image/armv8.mk这个文件夹里，去掉注释#，如下：
```patch

5. 然后参考下载源代码，更新 feeds 并选择配置等等，即可编译你需要的固件了
