你好，这个是什么问题？单片机型号是：CH32V203F6P6

同样是V182版本，两台电脑，一台让我切换到2.6，一台让我切换到2.7

您好，该问题可能是芯片读保护开启了导致的，可关闭读保护后再次调试。MRS V182在安装最新的芯片开发组件（计算机联网后会获取组件更新推送，支持自动下载安装）后即可使用V2. 7版本WCH-Link固件。

现在报的错误：

Error: Hart isn't halted before single step!

Error: unable to step rtos hart

您好，请问一下下载会有问题么，任一程序Debug都会出现该问题还是特定程序会有这问题，若方便可以把出问题程序发我邮箱（lzs@wch.cn）这边测试复现一下，后续问题也可继续通过邮箱和我沟通，这样更方便一些。

程序已经发你邮箱了，麻烦了

您好，已邮件回复你，请注意查收。当使用MounRiver进行仿真的时候，需要注意代码中最好不要包含有FLASH的操作，不要有开启看门狗或低功耗模式操作。
