STVP无法连接到MCU

嗨，


我正在使用STM8S-Discovery板和STVD软件的编程器调试STM8S105x6的软件。

一切顺利，直到突然在进入调试模式时弹出错误：'**连接错误（u***：// u***）：游泳错误[30006]：通信初始化错误：芯片没有回答'。 STVP也无法连接到MCU。

我已经尝试过其他板子（以前有过工作）。我已经将SWIM电线直接焊接到威廉希尔官方网站 板上。没有任何结果。

当我第一次更换程序员时，问题仍然存在。但是有了第三个程序员，问题就解决了。

但过了一会儿，问题就出现了。

这个程序员似乎还可以，因为我可以在demoboard本身上编程MCU。

我不知道可能是什么问题。

关于董事会的更多信息：

*连接了SWIM的GND，复位和数据线。 VCC未连接
*复位引脚具有10nF的上限和10K的VCC（我试图去掉两者）
* VCC = 5V1

谁知道什么是错的???

问候，
约翰

Hi,


I am debugging software for an STM8S105x6, using the programmer from the STM8S-Discovery board and STVD software.

All went fine, until suddenly an error popped up while entering debug mode: '** Connection error (u***://u***): swim error [30006]: comm init error: chip does not answer'. Also STVP cannot connect to the MCU.

I've tried to other boards (that have worked before). I've directly soldered the SWIM wires to the board. Without any result.

When i changed the programmer a first time, the problem remained. But with a third programmer, the problem was solved.

But after a while the problem came back.

This programmer still seems to be ok, because i can program the MCU on the demoboard itself.

I have no clue what can be the problem.

Some more info about the board:

  * GND, reset and dataline for SWIM are connected. VCC is not connected
  * The reset pin has a 10nF cap to gnd and 10K to the VCC (i have tried to remove both)
  * VCC = 5V1

Anyone an idea what is wrong???

Johan
