STM8L-Discovery Debugging

Hello,

I use the ST Visual Develop IDE together with the Cosmic Compiler and the STM8L-Discovery.

Everything seems to work fine, besides the debug function.

When I try to start debugging I get the following error message:

''Connection error (usb://usb): swim error [30200]: st-link connection error''

I found discussions of Linux users about this topic, but I use Windows...

Any idea how I get this to work?

Thanks in advance.

Hi, after playing with the toolset dll, i've found out the following: first i took a copy of the stvp folder. installed 4.3 and replaces all stlinkusbdriver.dll (v4.2.2.0) with the old version (v4.0.1.2). Stangly the new V4.2.2.0 is only 64Kb while the old one is 380Kb in size. So it is possible that some other conflics arrive with this change...
