My project stop running after migration to STM32CubeIDE v1.17.0

[Engin Lee]

Hi,

My project use STM32H750IBK6 MCU and it works well with STM32CubeIDE v1.16.1.

But it stop running after migration to STM32CubeIDE v1.17.0 with FW H7 V1.12.0.

Any suggestions?

BRs,

Hello @Engin Lee 

Have you selected the option Migrate or Continue on the pop-up you have added to your post.

Yes, it goes without any problem if I select "continue" button..

But it stop running if I select "migrate" button, compile program and then flash.

Hello @Engin Lee 

It works fine on my side: 

Could you please uninstall and reinstall both CubeMX (V6.13.0) and CubeIDE (V1.17.0) and retry.

Best Regards.

Sorry, I mean the compiled code stop working on the machine, not stop compiling.

I tried uninstall and reinstall CubeIDE (V1.17.0) and H7 SDK (V1.12.0), but nothing changed.

I tried disable ARM core D-cache and FreeRTOS tickless option, but without luck.

I didn't find any significant changes in HAL and LL driver which make the system down, could it be possible that I am running code in RAM (0x24000000) where is loaded by bootloader?

Hi @STTwo-32 ,

Today I have a chance to dig this issue again, and finally I find the problem.

In the H7 SDK V1.12.0, something changed in HAL_RNG_Init(), like this difference:

It seems to be a longer time to wait for a random number generated.

And I am using LSI clock source for RNG in my product, if I modify RNG_TIMEOUT_VALUE from 2 to 200 like this:

#define RNG_TIMEOUT_VALUE 200U //before: 2U

Then the program can continue run without blocking.

So could you review about RNG_TIMEOUT_VALUE to a reasonable value for different clock sources?

Thanks,
