EEPROM config and the CM5 lite

if you applied the EEPROM changes as outlined in the OP then it should work. you should also get hdmi output no matter what. i’d reseat everything just to be sure.

EEPROM changes again applied with the Geekworm X1500-C1 board.
Build back in uConsole - no success.

Is it normal that on batteries same as when on a charger - even after 10 sec pressing the powerbutton the green light gets only lower but never turns off? Only thing to turn it truely fully off is unplug batteries and cable in my case…

With the CM5 you can’t hard shutdown the device, the power reset pin is different then the cm4 that the adapter board is designed for. So you’ll have to remove the batteries. I’d just run on mains power till you get it booted so it’s easier to reset.

I’m using a CM5 and mine turns off the green light totally when I shutdown. I’m using Trixie.

Shutting down works fine, it’s trying to hard power down when the kernel isn’t running. The cm4 if you hold the power button for 10 seconds the pmu will power down. The cm5 won’t signal the pmu to shut down so there’ll be a dim green light and the pmu will still be drawing power.

Thanks for the feedback!
You at least got some screen up though, i never even got any signal on the built in screen or HDMI.
Personally not 100% sure yet if its maybe the Pi (got the same 16gb model), io board should arrive next week.

Will be following, keep us updated!

got it working: just by flashing again the bootloader via SDcard (Raspberry PI Imager) via a different board: https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#raspberry-pi-boot-eeprom
Now without further changes everything is working - no config change nothing else..

Awesome! That gives me hope that its just a quick update when the IO board arrives.

Glad you got it working!

Rex, do you think it will it be possible to use this adapter with the EMMC cm5?

What adapter? The cm3 to cm4 adapter? If so yes it will work with the emmc cm5. With the emmc cm5 you won’t have to edit the eeprom though.

and you still need a developer board to flash emmc

ok, thank you. I was speaking of this new nvme board, my apologies for lack of clarity.

yes both the new adapter boards coming out will work with the emmc cm5.

Oh yes. I already damaged the mezzanine connector on my cm5 swapping it back and forth so much. Looking forward to just pulling and flashing a drive.

so cm5 with emmc can’t see SD card right? , got ubntu installed display/keyboard works, wi-fi -no any advice?

yes

Doesn’t see anything. Devices are listed i tried also usb wifi dongle but mmcli list is emty and ifconfig shows down and not turning on

default position of antenna is awful and too deep in metal case. try to get close to wifi point and try again or run hotspot on mobile and try connect to it.

if you will see anything – put some foam like 2-3mm between antenna and case (like 2 sides tape),
or try some other external antenna: Replacement wifi antenna - #118 by mex

yep i’m with laptop antenna on foam and had excellent signal on cm4 . usb wi-fi also not working , drive works. possibly drivers ?

if you’ve installed rex’s ubuntu: Ubuntu 24.04 6.12.y for the uConsole and DevTerm

drivers should be in there

and I suppose you did because on vanilla ubuntu you won’t have uconsole’s display drivers :slight_smile:
