Just put together my uconsole. I’m having trouble getting picture to the lcd. These are things I’ve tried.
Reseated the lcd ribbon cable
Completely dissembled everything and reseated core module, cm4, cellular module.
Flashed different sd/os image.
Tried just powering it up with usb-c.
Powering it up without cm4, and lte module.
Just powering it on and waiting a while.
I plugged in a mini hdmi and I was able to receive picture to external monitor but it doesn’t fully boot up. Also in the being of loading it does say SD card not detected. Then it’ll get to networking and sort of repeat everything. Not sure what’s going on here. Just figured I’d reach out here before contacting clockworkpi support.
If you hold the device at a slight angle while powered on, you should be able to see a green led glowing around the port inside while looking through the HDMI or Audio opening in the case like you can see in the picture. I was also having issues getting my A06 going after assembly.
I also discovered the button push timing was important.
Hold 3 seconds to power on
Hold 12 seconds to hard shutdown (will see green led go dark)
You have any luck? I haven’t had much time to fool with it but I flashed another SD card this evening without success. Mine also flickers for a split second upon pressing power but that’s it. Starting to suspect I got a lemon.
Yeah I tried a few different power supplies, one being my steam decks . I think the issue is my CM4 has 8gb emmc and it’s trying to boot from it. I forgot that it won’t boot from SD because of this reason.
I’m 90% sure that’s the issue. The problem is the cm4 is trying to boot from eMMc and there’s nothing on it. I’m confident once my CM4 lite arrives it’ll boot up no problem. I’ll report back with that confirmation when I receive it. If you didn’t want to go though the hassle of buying another one you could buy the I/O board and flash the eMMC but then you’re limited in terms of space
Yup, and don’t worry if you don’t have a 4G card, it’s not required. It if you have a 4G model, it will run fine even if the 4G card slot is empty. ~ Cheers!
I too have a dark screen. I tried the hdmi method above and got to a screen for finishing up on the external monitor, now the trackball won’t work. I reflashed the card with Raspberry OS 64-bit on the imager. Even disassembled the uConsol and put it back together. Same results. Booted with batteries and without. I’m out of ideas. If I need a new board, where can I get one. Thanks in advance.
Thanks Rex. It there some site that explains compiling. I am a little unfamiliar with this process. I tried the Ubuntu distros and nothing happens. it seems to loop,’ looking for nvme’ ‘can’t find sd card’ even though one is installed. I fail to understand why the original data that shipped with the uconsol doesn’t work, much less find it. The hdmi method does work to some extent. Thanks again.
on most images during the first boot it will resize the FS and reboot. you should give my Debian Bookworm image a try. everything works as it should, it’s a decent way to test if your hardware is bad.
Rex, again I would like to thank you for your help. After much gnashing of teeth and pulling of hair, I was able to get the Bookworm file, and install it. Everything now works as it should. Have a great day!
I’m curious though .I habe the no core version, because I was gonna get a cm4 later. I was told that I could use the uConsole without a core as long as I flash an sd card with the proper os . Is this true or so I need a cm4lite ?
will try it out once it arrives & update here too
