I am trying to get debugging work on an STM8S-Blue board using PlatformIO and an STLink-V2 clone on a Windows 11 PC. I am using the official spl-blink example. The code compiles and I am able to upload it to the board. The code runs perfectly.
What I can’t get working is the debugging. The debugging fails with the following message, in the Debug Console tab.

I have been reading about similar errors reported here, as well as in GitHub. Is this some issue with SDCC?
