## 下载依赖的软件包
|
||||||
|
|
||||||
|
在软件包无需变更的情况下只须执行一次
|
||||||
|
```
|
||||||
|
source ~/.env/env.sh
|
||||||
|
pkgs --update
|
||||||
|
```
|
||||||
|
|
||||||
|
## 将根文件系统编译进内核
|
||||||
|
|
||||||
|
为了方便测试，这里将根文件系统制作成CROMFS格式转换成C代码编译进内核。
|
||||||
|
|
||||||
|
1. 在 https://github.com/RT-Thread/userapps 页面下载riscv64预编译镜像
|
||||||
|
2. 解压后将其中的ext4.img挂载到一个目录中
|
||||||
|
```
|
||||||
|
sudo mount ext4.img dir
|
||||||
|
```
|
||||||
|
3. 删除其中一些不必要的文件以减小内核体积
|
||||||
|
```
|
||||||
|
du -ha # 查看文件大小
|
||||||
|
sudo rm -rf dir/www dir/usr/share/fonts dir/tc
|
||||||
|
|
||||||
|
```
|
||||||
|
4. 生成cromfs文件
|
||||||
|
工具位于 https://github.com/RT-Thread/userapps/tree/main/tools/cromfs
|
||||||
|
```
|
||||||
|
sudo ./cromfs-tool-x64 dir crom.img ./ # 将生成的cromfs_data.c放入applications目录
|
||||||
|
```
|
||||||
|
|
||||||
|
## 编译
|
||||||
|
|
||||||
|
```
|
||||||
|
export RTT_EXEC_PATH=/mnt/e/tools/riscv64gc/bin # 你自己的编译器路径
|
||||||
|
|
||||||
|
scons -j8
|
||||||
|
```
