STM32CubeIDE version 2.1.0 won't generate IOC project file

Geoff104 · ‎2026-03-06

Hi,

I have recently upodated STM32CubeIDE and have found that starting a new project doesn't generate a *.ioc file. I found a forum thread dated 7/2025 to a similar issue in versions 1.17-1.19 but the suggested work around menu options don't appear to be in v2.1.0. Any ideas?

this is really annoying as I've got a 'journey to complet'e but I'm wasting my time getting the 'car to start'....

This is intentional, and documented here and here.
