Debugger exits automatically.

[Dsasa.1]

When I try to debug with CubeIDE, the following happens

1. start debugging

2. program is written and debugger is attached successfully (startup sound is heard at the board side)

3. break in HAL_Init() in main()

4. resume (proceed to the next breakpoint)

5. debugger exits and returns to 1, but HAL_Init() will not break thereafter

6. repeat this 3 times to finish debug mode (changes on GUI)

After debugging starts, nothing is done except to restart the HAL_Init() break once at the beginning.

This occurred with CubeIDE 1.9.0. Previously, we were using 1.1.0, where the problem did not occur.

 I am not sure what is causing this problem, partly because I don't really understand what is happening during STM32 debugging. I would like to know the cause and solution.

Thank you in advance for your help.

Execution environment is macOS Monterey.

Hello there!

Could you try to create a new workspace with a new project with STM32CubeIDE 1.9.0 and see if it's the same behavior with the new project?

If the behavior is the same, could you try to switch debug probe to OpenOCD to see if anything changes?

[Dsasa.1]

Sorry, I wrote it wrong...

Sorry for the delay in replying.

> Could you try to create a new workspace with a new project with STM32CubeIDE 1.9.0 and see if it's the same behavior with the new project?

There was no change (same behavior)

> If the behavior is the same, could you try to switch debug probe to OpenOCD to see if anything changes?

I think they behaved almost identically. Couldn't debug it.

It seems to have been rebooted several times. This error message was the last one left.

After this, I restored the settings (debug probe to OpenOCD to ST-LINK) and was able to debug successfully.

I don't know why...

Has the problem been solved?
