Issues when programming STM8 using STVP on Windows 11

[DanielEaston]

I have a Windows 11 machine with the ST toolset (including STVP) installed on it.  I have an ST-LINK V3 connected and the drivers are installed correctly (the device is working correctly reported by Device Manager).  I'm using:

board_name = ST-LINK
port = USB
tool_prog = SWIM
device = STM8AF6266

I can use STVP to flash the main program and the memory but I get an error when I program the option bytes (I don't have the Win 11 machine in front of me at the moment so can't be specific on the error).  I have exactly the same set up on my Win 10 machine and have no issues so my guess is it's a Windows 11 thing.

Does anyone have any experience of this issue?  Is there another tool I can use on Win 11 to programme an STM8?

Any help gratefully received

I can try.

For information, I resolved the above issue.  It wasn't actually specifically related to Windows 11.  I had an STM32 and an STM8 being programmed from a single ST LINK V3 and there was some stray voltage paths that were causing inconsistent behaviour.  It was much more reliable on Windows 10 than 11 though.
