Is there a way to run STM Studio under Linux? Or is there any alternative?

Btw. I'm trying to monitor the variables used in code. STM Studio does this under windows in realtime.

Not sure if ST even considers supporting Linux here.

You could try Wine, or a Windows VM.

Running with windows in a virtual machine, e.g. Virtual Box, would be an option.

For wine, hardware access needs a wine compiled STLinkUSBDriver.dll. Api calls could be redirected to libSTLinkUSBDriver.so, but that would mean that the APi is public documentend. I don't know of any such public document.

BTW, I'm being pragmatic here, and use dual-boot systems at home.

I use to shrink the Windows partitions coming with new PC to a minimum before installing Linux.

Starting up Windows once a month or less, for exactly those reasons. The Windows itself stays isolated (no network/internet connection, no virus scanner etc.).
