STM32CubeIDE: .ioc File Not Generated and Toolchain Not Set (Target IDE is Empty), Even After Updating

[SM7389]

Hello ST Community,

I’m facing a persistent issue while creating a new STM32 project using STM32CubeIDE, and I need some technical support.

Problem Description: version 1.19

• When I create a new project, the .ioc file is not generated.

• The "Target IDE / Toolchain" field shows as empty (not STM32CubeIDE).

• Because of this, the project does not build or open properly in the IDE.

• I have selected the correct microcontroller, like STM32F103C8T6, but the problem still occurs.

Steps I followed:

1. Opened STM32CubeIDE

2. File → New → STM32 Project

3. Selected correct MCU

4. Gave a valid project name

5. But the project doesn’t target STM32CubeIDE and no .ioc file is created

What I tried:

• I updated STM32CubeIDE to the latest version, but the issue still exists.

• I tried restarting the IDE and creating the project multiple times

• I checked toolchain settings, but nothing seems to be fixing it

What I need help with:

• Why is STM32CubeIDE not generating the .ioc file or setting itself as the target toolchain?

• Is there any way to fix or convert an existing project to include .ioc and select STM32CubeIDE?

• Is this a known bug or some misconfiguration?

Thanks in advance for any help.

Best regards,
Sachin Mewada
