I'm trying to power on a RPi 4 using the RUN pin. The RPi is runing LibreELEC (Leia) 9.2 ALPHA1. I tried shutting down the RPi from LibreELEC's GUI, then grounding the RUN pin for a second by connecting it to the pin next to it, but nothing happens, the RPi doesn't boot. Previous models of the board could be powered on this way, did something change?
I should add that the board correctly resets when it's powered on. I just can't power it on when it's in a halted state, which I expect from a reset pin.
When looking at the schematics, I don't think I'm doing anything wrong.
