stm32N6570-DK cube ltdc and debug error

[Omerza]

Hi,

I am using the STM32CubeIDE project for the STM32N6570-DK kit.

After enabling the LTDC RGB888 interface, I received a warning (yellow) related to the DEBUG configuration.

I am using “DEBUG Trace Asynchronous SW,” and the message indicates that the DEBUG is partly disabled due to a conflict with LTDC.

Could you please explain the reason for this conflict? As far as I can see, there are no shared pins between the interfaces.

Could this issue affect functionality in any way? Also, how can this warning be resolved or removed?

Thanks,
Omer

You haven't said what version of CubeIDE you're using, but it seems to be an older one - with CubeMX integrated?

Latest versions of CubeIDE (since v2.0.0) have CubeMX entirely separate:

I am using STM32CubeMX.

Version 6.17.0

Hover the mouse over the yellow thing, it should show something explaining the conflict. The yellow color by itself does not mean "too bad". No the warning cannot be removed.

The SWO pin is optional, try another debug mode without SWO pin, if possible.

Attached a snap with the message. Conflict with LTDC.

I try debug at serial wire mode it is not include SWO pin. Only 2 pins but still the same message. Those debug pins are not used in LTDC or other function.

same when I tried JTAG with with Trace Synchro (1 bit). or 2 or 4 bits.

Now I see that even when it is under disable mode it shows this message.

Well, if you are sure that PA13,14 do not actually conflict with LTDC  - just ignore this and go forward.
