Hello.
I have 2 devices with a CM4 module and a custom PCB. One CM4 Lite, the other with eMMC. (If there is a difference)
I am using GPIO4 to control the DE signal of the RS485 chip via Node Red.
Everything works properly on the eMMC module. The second one returns "nrgpio python command not running".
OneWire is disabled. Python 3.11. Standard OS. Node Red installed by script.
The problem only affects GPIO4.
Unfortunately, I haven't found any solution at the moment. I would appreciate your help.
