I upgraded CubeMX to 4.26.0!
Migrated my existing project to 26.
Generated source code for Atollic TrueStudio 9.0.0
When I compile with Atollic TrueStudio 9.0.0 under Ubuntu
the Post-build step: "arm-atollic-eabi-objcopy.exe ..." failed because program not found.
Updating TrueStudio project setting: C/C++ Build/Setting/Build Steps/Post-build step
Saved the day, however - The windows style program name reappears with every source code generation from CubeMX
