have you tried with a monitor conected to the hdmi port to see what is on the screen, sometimes it needs a key press to move on that will not come up on the built in screen at that point.
the one next to the RTC battery socket is not used.

I didn’t think so, but I wasn’t sure, so thanks for the clarification on that.
Just wanted to gather opinions:
What does everyone think is the best OS for Uconsole running the AIO and upgrade setup? Bookworm? Trixie? Any other nominees? I like bookworm with how I run it now, with a CM5 and the full expansion kit from HG.
I see a lot of good things about Trixie. Haven’t tried it yet. I’ve had some issues getting certain things to run on bookworm, particularly pentesting tools. Does Trixie face the same issues?
Bookworm is a dead end. Development on it has stopped. It’s very good but you won’t see any great new things running on it. Trixie is in active development so if you want an open upgrade path, Trixie is for you.

So i installed the upgrade kit tonight, installed an NVME SSD and formatted it then created some files on it just to insure it worked all the while having my SD Card in. No problem uconsole CM5 worked fine. Then from the SD Card I downloaded a current Trixie Image and used the following command from where I had the image on the SD Card: sudo dd if=2025-12-04-raspios-trixie-arm64-full.img of=/dev/nvme0n1 bs=4M conv=fsync status=progress No issue the image copied over I checked the disk space on the NVMS and yup it used some disk space. Now here is where i ran against a brick wall. I powered off the console then removed the SD card (I had previously modified the config.txt file) but the screen remains black now nothing not even a brief flash of anything. Is there something I didnt do in order to now boot from the NVME? The only inclination I have that something is “on” is the power light does light up when I press it. Thats it… any suggestions?
OK after sitting here thinking I believe i know what I did, while i modified ALL the necessary files on the system while the SD Card was in I did not modify anything on the NVME. So i am going to put it back the way it was and modify what I need to on the NVME side and see where I stand afterwards!
i was about to ask which config.txt you edited haha. i think that will do the trick for you!
OK this is turning into a time consuming nightmare.. Flashed the newest Trixie OS to a new SD Card. According to chatgpt i didnt have to modify any files just put it in the uconsole and boot. WELL that didnt work. Power Light on no screen activity and no backlight.. Using chatgpt guidance its now having me go down the use rpiboot to flash firmware but i cant get rpiboot to recognize my CM5 (installed in the uconsole) using a usb-c cable (known good data cable). HELP oh world of the uconsole geeks im in need of help! Also im doing this from a Ubuntu 25.04 machine. On the new upgrade kit CM5 host board there are 2 micro micro switches one labeled 1:nRPIBOOT and the second labeled 2:EEPROM_nWP does the RPI BOOT switch need to be on or off and which way is on/off?
On the new upgrade kit CM5 host board there are 2 micro micro switches one labeled 1:nRPIBOOT and the second labeled 2:EEPROM_nWP does the RPI BOOT switch need to be on or off and which way is on/off? To the right or to the left?
So i shall await someones response from this post as all my free questions for the day have been used up on ChatGPT
Yes and yes!
(i’m so sorry i couldn’t resist)
Right on. You’re not the only one. Here’s my predicament and what I discovered…
I have a Uconsole with a CM4, running bookworm. Runs great.
I got the CM5 with EMMC and the HG upgrade kit with NVME and all that, AIO board too.
I used my CM4 to flash the CM5 EMMC. Rpi boot should see the EMMC, both those switches should be flipped to the ON position. Then run that, then imager.
I too am having issues with the newest Trixie not working properly. It was, then I updated it, then went to reboot and I get a black screen with no responses when I try to power down. Had to pull batteries.
Reflashed the EMMC the same way as I said before, with the Uconsole with the CM5 removed and had the CM4 in there with Bookworm.
Idk what the issue is, but even after reflash, Trixie is not functioning at all. Lights are all on, but black screen of nothing, even after reflash.

I got it working! Thought I hasd the latest bookworm, but alas… reading really IS fundamental! Downloaded and installed that and was off to the races. Literally… that nvme smokes the sd card on speed.
Thanks to all who assisted. Solid community!

I like the trixie build as it has the new bookshelf app
have you ever considered having two 2230 size m.2 ports instead of the one that can go up to 2280?
In a bit of a pickle here fellas… need help…
So, just getting it out of the way, with the CM4 in, the Uconsole works perfectly fine.
When I reflash the CM5, boot takes a while. But happens upon initial setup. I do location and login settings and all that and reboot and it sometimes works, sometimes doesn’t. That’s with NVME removed. When I insert NVME with power off, nothing happens when I go to boot again. This is going on consistently after about 7 re-flashes. I’ve tried Trixie and bookworm. I don’t recall hot mounting the NVME ever. It’s a high end Crucial NVME. But the NVME wasn’t even in the boot order before the EMMC after new re-flash. I adjusted boot order after I got it to work like twice and boot by itself, then after I prioritize NVME, it no longer works. Same issue as before. Black screen and unresponsive.
Is this a PCIE controller issue? Nothing seems wrong with the CM5 itself. It’s just taking a while to boot initially off the EMMC.
Need help bad here. Thanks!
i made this comment 7 days ago which might be your issue too. just found dtparam=pciex1=off in my config.txt just changed it to just dtparam=pciex1 and it now sees the drive on my nvme hat so am just going to try the socket on the battery board again to see if that works now that the config.txt file has been changed, one to look out for as i used a trixie build from this group for the cm5 so others might also have it set to off.
you have to make this change on the nvme drives boot partition.

Okay! I’ll give it a shot. Is that a fix for the total absence of booting? Cause I usually can’t even get it to boot of the EMMC…
are you removing the m.2 drive completly when trying to boot from emmc?
There are two more on the bottom of the AC1200 Wi-Fi card. The product page needs to be upgraded.
