Having some issues with my Pi4, I'm running it headless right now, but it's getting the link up for the ethernet, starting up the external drive and then nothing... I can't ping or SSH into the device and my router doesn't have a ARP entry for it..The SoC is hot to the touch, so it's not in a a halted state.
The last things I did before I rebooted it and it got stuck in this was enabling the VNC server via raspi-config, and increased the GPU memory to 256mb.
To debug whether i'd done something to the OS, I switched out the Pi4 to a Pi2, same SD card/Hard drive, ethernet etc.. This device boots fine, and i'm able to SSH into it, etc.
Have I possibly somehow killed my Pi4 already? I've left it a good 20 minutes just to make sure it's not decided to do a fsck or something, still nothing.
If you need anymore info, let me know. Can't see or identify anything that could be causing a fault apart from the hardware of the Pi4
