I am porting a design with Ethernet from VCU118 to VCU128. I was wondering how to proceed about the RESET_B port: will the PHY get a reset during the power cycle, or is it mandatory to control the PHY GEM3_ENET_RESET_B pin?
If reset must be controlled explicitly, is there a reference design to do so on the VCU128, for which the pin is behind the port extender TCA6416A?

Hi @paul.mnt ,
You have mentioned GEM3 reset pin in your post. Just to confirm first if you're talking about MPSoC device or VCU128? GEM3 is the Hard Gigbit ethernet controller inside of the PS on MPSoC.
