Picade not working on Pi 5 but does on Pi 4, seems starved for power

Hello, I understand that picade isn’t officially supported.
[Edit, officially supported on Pi 5 rather]

I’ve done my best to follow instructions to get it working on my Pi 5 by starting with these instructions:
https://www.reddit.com/r/RetroPie/comments/187ix5n/raspberry_pi_5_and_retropie_installation/

Then following these instructions:

The issue is appears to be something related to how the Pi 5 is handling power.

The Pi LED will start flashing green then go out, then appear to restart and repeat this.

Not a blinking sort of way but a “help me I don’t have enough power” sort of way.

Giving the screen it’s own USB power source doesn’t help this.

I can pop the picade hat off and stick it on a pi 4 and everything just works which leads me to believe this is a configuration issue.

I’ve done the “usb_max_current_enable=1” thing and it didn’t do the trick.

Are there any triaging suggestions you can give me?

Or am I better waiting for an official version to be made available.

Thank you!

Hi Thats Strange, it worked for me. Do you get a Video Signal ?

I connected the lcd to the usb c port of the pi itself via usb a to usb c adapter

So all the usb Ports from the pi are free.
I don’t Know if thats make a difference, but my Setup Works Fine That way

Hey, thanks for taking the time getting back to me.

I thought about maybe reducing the parameters and removed the picade hat all togehter and the behaviour’s still happening so clearly I’ve done something wrong to configure it for the Pi 5.

Probably an HDMI detection setting or something.

The power starved thing must just be it indicating “I don’t know which display device to use”.

I’ll play around some more and try to get the display coming up properly without the Picade hat as a starting point then go from there.
