I setup my Picade today and really enjoyed the process. Found the written instructions on the website to be very good - thank you.
However, I’m now having problems with the initial setup on a Raspberry Pi 4 with 8GB.
My MicroHDMI cable was plugged into the MicroHDMI port furthest from the USB A connectors as suggested in the instructions. On first boot, I was getting a ‘No Signal’ error on the screen before and after uncommenting the hdmi_force_hotplug=1 line from /boot/config.txt.
The only thing that fired up the screen was to switch the MicroHDMI cable to the other MicroHDMI port. The system booted and I could see the Retropie logo. I was able to go through the various setup routines, enabled wifi etc. Everything was fine until I installed the Picade HAT software using curl https://get.pimoroni.com/picadehat | bash. After the next reboot, although I could see the initial boot sequence, when Emulation Station started, it failed to show on screen. All I could do was hit F4 once it was loaded and I was dropped out to a Raspberry Pi command prompt (which I could see on screen).
There’s another thread here the describes a very similar situation and fixed it by switching to the other MicroHDMI port (the one I started in). I’ve done that and I am no longer getting a ‘No signal’ error on the screen. The Raspberry Pi is booting and loading Emulation Station but I can’t see anything on screen (the screen is backlit but not displaying anything). Eventually when it’s fully booted, I can drop to a command prompt by pressing F4 and reboot or shutdown from there even though I can’t see the anything on the screen.
I hope that’s clear and would be grateful for any assistance to get properly up and running.
