-
ROCK3 Model A的默认波特率为1500000(1.5Mbps)，检查FT232 USB转UART串口模块是否支持 1.5Mbps 波特率,我们这里使用的是FT232 USB转UART串口模块。

-
将type A双公口USB3.0线一端连接电脑USB端口，另一端连接ROCK3 Model A的OTG接口（Rock 3A上方的USB3.0接口）
-
先给ROCK3 Model A接通电源，然后保留左边“1”处排针上的跳线帽，拔掉右边“2”处两个焊点的排针和跳线帽。

RKDevTool工具烧录
打开瑞芯微刷机工具RKDevTool，此时会看到设备处于“maskrom 模式
双击第二行“Parameter”，将名字改为“image”
勾选第一行“Loader”和第二行“image”，在①处选择放置rk356x_spl_loader_ddr1056-固件位置，在②处选择放置镜像Radxa的路径。
点击执行，就可以看到右边写入内容了， 显示下载完成就写入成功了，同时也会显示没有发现设备，拔掉“1”处跳线帽，拔掉电源,重新开机，ROCK3 Model A开机成功后，会看到板载的绿灯常亮，蓝灯闪烁。
