st8 Discovery gdi-error [40201]: can't access configuration database

Hi,

I'm trying to use the ST Visual Develop with the Cosmic st8 32k compiler.  I install everything and build the project.  That all works fine.  When I try to connect to the Discovery board with the debugger using Swim ST-link, I receive the following error:Starting debug session... -> Emulator reset (usb://usb)...  ** Connection error (usb://usb): gdi-error [40201]: can't access configuration database -> Failed to connect target.I have tried uninstalling and re-installing everything including the drivers.  I've tried other target settings.  The only one that works is the simulator.When I connect the Discovery board, my computer sees it as an external HD.  I get the pop-up window and can look at the links stored on the board.  I'm using Windows 7 64bit.I should also add that after the above error message a windows 7 pop-up appears saying that gdb7 has stopped working and a red LED glows on the board.Any help would be appreciated.Regards,Marc #stm8-discovery #i-also-get-same-error-so-please

Hi there. I am facing same issue. Did you find any fix?

Thanks a lo0ot. This worked for me. Only one thread on google which is talking about this issue.

Running 'ST Toolset.msi' did not work for me (both as normal user and admin) but I found my solution here:

https://community.st.com/s/question/0D50X00009XkXhpSAF/stlink-v2-configuration-database

It says:

You will need to open a command prompt in administrator mode. For those that don't know you will find it at

Windows/Start button->All Programs->Accessories->

Right click on 'Command prompt' and select 'run as administrator'

First type this one

Regsvr32 /u "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL"

And then this one

Regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL"

This unloads and then reloads the DAO DLL which fixes the problem nicely. It also assumes you have a standard install of Windows so if you put DAO350.DLL somewhere else then you will have to change the paths.

You might also have to cd \windows\system32 before anything to use regsvr32 but mine defaults to there

I tried the STtoolset.msi repair - not fixed

Did an uninstall / reinstall - fixed it.
