SDK源码解压与恢复
::: tip
这里注意要 mkdir sdk 目录里解开压缩包
:::
tar xvzf rv1126b-linux-xxx.tgz为什么呢？
因为他解开后是git，你看不到，在.git目录下。所以，你到sdk目录下解开压缩包从git中恢复完整源码
git reset --hard 安装必要的 库

配置内核
./build.sh kconfig进入配置菜单选择你要的内容
编译内核
./build.sh kernel 复制结果
kernel-6.1/arch/arm64/boot/dts/rockchip/pro-rv1126b.dtbkernel-6.1/boot.img其中dtb文件路径 编译的提示里有。
把两个文件复制到 U盘里
注意 要用fat格式的U盘
启动Uboot 按Ctrl +C
在命令使用u盘
usb start等到找到u盘fatload usb 0 0x81000000 boot.imgfatload usb 0 0x48300000 pro-rv1126b.dtbboot_fit 0x81000000这样就可以启动内核了。
