Mounriver不能进入单步调试模式？

使用Mounriver生成的默认工程CH32V103C8T6，官方的开发板，下载程序可以运行，打开串口能够收到信息。

在Mounriver的debug模式下，点击debug菜单，报错，不能进入调试代码状态，信息如下：

Mounriver软件和WCH-LINK 都是最新版本，请问可能是什么原因？我怎样才能够单步调试？

我还没有换，从立创商城买了批号401939B40，不知道能否解决问题

我手头上的 CH32V103R-R1-1V1感觉也是这样的问题，芯片型号是 CH32V103R8T6 批次号为:401926B03,是不是换一片最新的芯片就解决问题了?

看芯片都能看出版本批次来？

谢谢，这个批号401925A28，立创商城在售的片子是新版本的吧，采购时捎带一片，换换试试。

您好，你这芯片可能是较老版本的芯片，可联系我们销售申请一下新版本的样片。

换这个CH32V103R-R0-1V2的小板子，下载，单步仿真正常，说明是CH32V103C-R1-1V0的问题，硬件如果出问题了吧，download又正常，莫名其妙？

使用CH32V307-EVT-R1，进行调试，首先提示必须升级WCH-linker固件，没有问题，升级后，CH32V307，可以单步调试

将CH32V307-EVT-R1的wch-linker，外接CH32V103-R1-1.40，下载程序没有问题，信息如下：

可以选择调试，依然进行不下去，信息如下：

看提示信息，似乎是wch-link选择了jtag，且jtag的速度配置的不合适，mounriver里面找不到配置wch接口和速度地方，wch-linker只有swd接口吧，怎么还有jtag的事？

Mounriver不能进入单步调试模式？
