Hello, I am working on a project using the stm32mp135d and would like to use its PoE feature.
Other than being mentioned, and some tidbits in the schematic I can’t find much documentation on how I should expect the PoE to perform. When I plug a PoE injected ethernet cable into ethernet port 0 (the outer one), I read 12v and GND on the jumper pins close to the the RJ-45 port closer to the inside of the board (sorry I can’t post a picture).
However, the board does not boot up. The other two pins appear to be floating, which aligns with what I see in the schematic.
So what am I supposed to do here to get PoE to work? I have tried jumping VC1 to VC2 and VC3 to VC4 and still the board never powers on or even draws current.
