Toybrik RK3588 npu内核0.8.2升级到0.9.3

一、准备工作

（1）获源代码、rootfs.img和npu所需内核

（2）在Ubuntu22.04的x86系统搭建编译环境

官方Ubuntu系统安装依赖

sudo apt -y install python lz4 coreutils qemu qemu-user-static python3 \ device-tree-compiler clang bison flex lld libssl-dev bc genext2fs git make

结果：一直报错

自己的安装依赖步骤

1、安装lz4

git clone https://github.com/lz4/lz4.git cd lz4 make sudo make install

2、安装qemu-user-static

sudo apt-get remove qemu-user-static sudo apt-get install qemu-user-static

或者

sudo apt-get install qemu-user-static sudo apt install qemu-user-binfmt sudo update-binfmts

3、安装device-tree-compiler

git clone git://git.kernel.org/pub/scm/utils/dtc/dtc.git cd dtc make

或者

sudo apt-get install device-tree-compiler

二、根据官方文档进行编译

参考

https://t.rock-chips.com/wiki/CN/tb-rk3588x/02-2Linux%E5%BC%80%E5%8F%91.html#id2

./edge set #执行如下命令编译生成内核镜像，保存在OUT_DIR目录： ./edge build -k

三、烧录镜像

替换images中的recovery.img、boot_linux.img、resource.img、misc.img文件，然后进行烧录。

四、烧录完成
