There was a problem hiding this comment. This whole thing needs to be cleaned up, the nodelabel should come from a board/SoC overlay. There was a problem hiding this comment. Yes! I agree with you. For this scope, I propose to do this cleanup in a dedicated PR. There was a problem hiding this comment. Once again, #81458 would help on this (to avoid multiple overlays). There was a problem hiding this comment. I will propose a PR later incorporating these suggestions. There was a problem hiding this comment.

What is the point? it's the same IP as stm32h735g_disco and stm32l496g_disco...

Yes, I understand what you mean, but I think it is valid for
integration_platforms, notplatform_allow. Without specifying this board, Twister will not run this test on the NUCLEO_H753ZI.Uh oh!

Exactly my point, we don't need it to, it has no added value.

Context of this change is to use
nucleo_h753zias "H7" champion on the test bench, so we need to it to be present everywhere.Cleaning up the number of boards present in these files is a good point, but we need to think about it more widely and it's likely a point for testing working group.

@erwango I don't think it's a great strategy to add a board like this everywhere without looking at the specifics of each sample/test.
As a starting point #94585
