I have an application that is using Node Red and the Automation Hat on a Pi4B without any issue.
However, I am trying this on a CM4 board with a Compute Module 4 IO Board. The basic python examples somewhat work, when I activate and deactivate the relays. However, the ADC ports (which I am not using) are randomly flashing, and the WARN light stays on. I can’t properly set the lights either.
Any idea where I should investigate next?
Thanks for your help
Here’s a link to the IO board
My module is a CM4001000 (CM4 Lite no wireless, 1GB RAM)
