I blink some leds from M7 and I see they don’t blink anymore.
I have rpmsg communication in place and I see that Torizon OS doesn’t receive any answer anymore.
The issue happens only on ETH0 (the one with the PHY on the SoM). ETH1 (with PHY on my carrier board) works.
I’m going to do other tests with the Yavia and a “standard” Torizon OS build to see what happens.
The GPIO bank is a hot topic and I’ve already had an answer from @rudhi.tx here.
I know that Toradex did a great job with the SoMs and Torizon OS and I appreciate it really much. But it’s clear that the interaction between the cores has been under-estimated both from the hardware and the software point of view.
I need a set of GPIO pins on M7 (and I think that if a user involves M7 it has real-time needs, and probably GPIO pins is one of the most common real-time needs) and so I need a clear answer on which GPIO pins are used by Torizon OS. In this way I can refactor my carrier board and use other pins on M7, but I need one final answer.
