## 1. 介绍
### 产品细节
https://www.rock-chips.com/a/cn/product/RK35xilie/index.html
### 支持列表
| 驱动 | 支持情况 | Earlycon |
| ------ | ---- | ---- |
| RK3576 | 支持 | earlycon=uart8250,mmio32,0x2ad40000 |
| RK3588 | 支持 | earlycon=uart8250,mmio32,0xfeb50000 |

## 2. 编译
使用RT-Thread Smart 专用工具链进行编译:
```plaintext
wget https://github.com/RT-Thread/rt-thread/releases/download/v5.2.0/aarch64-linux-musleabi_for_x86_64-pc-linux-gnu_242520-979be38cba.tar.bz2
sudo tar -xf aarch64-linux-musleabi_for_x86_64-pc-linux-gnu_242520-979be38cba.tar.bz2 -C /opt
```
将工具链下载后,解压至/opt目录。并设置环境变量
```shell
环境变量配置为：
export RTT_CC="gcc"
export RTT_EXEC_PATH="/opt/aarch64-linux-musleabi_for_x86_64-pc-linux-gnu/bin/"
export RTT_CC_PREFIX="aarch64-linux-musleabi-"
export PATH="$RTT_EXEC_PATH:$PATH"
```
进入`rt-thread/bsp/rockchip/rk3500`目录下输入:
```plaintext
scons --menuconfig
```
选择并拉取zlib软件包
执行一下命令拉取软件包并编译
```shell
source ~/.env/tools/scripts/pkgs --update
scons
```
## 3. 运行
RK3500 根据不同的板卡有不同的内核安装方法，建议安装到 SD 卡中，这里以Orange Pi Compute Module 4举例说明：
连接开发板串口：
1. 打开串口工具，选择对应串口，设置波特率为1500000
2. 将上述生成好的rtthread.bin放置sd卡中
3. 开发板上电，键盘点击`ctrl + c`进入uboot命令行模式
4. 输入下述指令运行smart系统
```shell
fatload mmc 1:1 0x480000 rtthread.bin;booti 0x480000 - 0x8300000
```
```plaintext
