Hi,

We have discontinued the Texane debugger as it was less reliable than OpenOCD. You can still download it from github and specify as “custom gdb stub”, but we no longer ship a pre-built one with VisualGDB.

Slow loads could be the case if you are using a VM with USB virtualization, but should normally not happen on physical machines. If you are not using a VM, please try enabling the timing analysis mode in the GDB Session window and then check which command takes most of the time. Perhaps you are programming a large image with OpenOCD and a smaller one with the ST tool?

Hi,

You would need to download Texane ST-Link sources from github and build them.

Then you can actually reuse the definition file that we made when we supported it officially: create a %LOCALAPPDATA%\VisualGDB\EmbeddedDebugPackages\texane folder and copy st-util and st-flash there. Then create a edp.xml file with the following contents:

This will add it to the list of VisualGDB’s debug methods so you won’t need to configure anything manually.
