Why no Synchronous Trace option for STM32G474RE in CubeMX?

[Anguel]

Hi,

I am trying to set Debug under Sys to "Synch Trace" in latest CubeMX but there is no such option for my STM32G474RE:

 

On other screenshots on the internet I see those options:

 

Any idea why?

Is Synch Trace not available on the 64 pin package???

Thanks,

Anguel

Hi @Anguel​ ,

thanks for your feedback. If I well understand you question, you're wondering why the JTAG and Synchronous Trace (1/2/4 bits) debug modes are not available for the STM32G474RE in CubeMX.

In fact those modes are not available for the LQFP64 package.

Selecting JTAG and Synchronous Trace (1 bit) for example will automatically activate PE2 and PE3 (TRACECK, TRACED0):

 

If you go back the STM32G474 Data Sheet, the TRACECK, TRACED0,TRACED1, TRACED2 and TRACED3 alternate functions could be only assigned to respectively PE2, PE3, PE4, PE5, PE6 and could not be remapped to any other pins :

 

I hope this answers question. If this is the case, please close this topic by choosing Select as Best. This will help other users find that answer faster.

Do not hesitate to raise any feedback or issue.
