The project is a TouchGFX demo running on the STM32H735G-DK.
Building works (vscode+plugin+cmake+clang). Flashing works with STM32CubeProgrammer.
Debug/flashing doesn't work with STM32Cube plugin, it does work with cortex-debug plugin with a custom launch.json file. Since that is incompatible with the plugin it will require using VSCode profiles and switch between them constantly.
If I try to debug using the plugin I get this:

I suspect this is because it doesn't load the flash loader for external flash. I don't know how to add this.
