 ## 注意事项
 
-波特率默认为 1.5M，需要使用 [Downloader](https://github.com/BLUETRUM/Downloader) 下载 `.dcf` 到芯片
+波特率默认为 1.5M，需要使用 [Downloader](https://github.com/BLUETRUM/Downloader) 下载 `.dcf` 到芯片，需要编译后自动下载，需要在 `Downloader` 中的下载的下拉窗中选择 `自动`；目前暂时屏蔽 uart1 打印
+
+使用 `romfs` 时，需要自己生成 `romfs.c` 进行替换，操作参考[使用 RomFS](https://www.rt-thread.org/document/site/tutorial/qemu-network/filesystems/filesystems/#romfs)
 
 编译报错的时候，如果出现重复定义的报错，可能需要在 `cconfig.h` 中手动添加以下配置
