You can calibrate the controller by:
- charge the device to 100%
- activate the calibrate function
echo 1 | sudo tee /sys/class/power_supply/axp20x-battery/calibrate
- drain the device to power off.
- charge the device to 100%

So if I just want to update my existing OS I just download the kernel package? I have the CM4 so I bet I need the CMr kernel?
If you’re running an older version of this distro, it’s possible but I’m not supporting it. If you downloaded this distro in the last 3 months then you should be able to just update to the newest kernel.
Time for a fresh install! thanks Rex. Buying you some coffee.

just flashed this to give it a spin, and everything seems to be behaving except something is weird with the keyboard layout. most of it is correct, but a few keys seem to be weird (the \ | key is typing # and ~, shift+3 is making a GBP sign instead of #, etc). ive got the default en-us and 105 key options selected from raspbi-config that it chose by default, not sure if theres a better option in there? didnt see one specifically for the uconsole keyboard anyway

Go back though raspi-config and reset the keyboard. The raspberry pi os defaults to GB keyboard.

Not sure if you’re still interested in hearing how the 6.12 kernel is working on a CM4, but I just updated my DevTerm this afternoon and it’s running well.
Thanks again for your work on this!

Hi, I’m new to Raspberry Pi systems. I finally picked up my CM5 and got to assemble my uconsole over the weekend. I flashed the main image on a brand new SanDisk. Eventually I was finally able to boot from the SD after a number of blank screens with the backlight on (I barely know what I did, but it happened all of the sudden. It also took me a couple of tries to realize I should have been running without the batteries in to make cutting power easier).
My question is: How exactly do I update the eeprom? Because I tried, it seemed like it was working, but the changes weren’t being saved. I must be missing something about the process. If it’s important, running sudo did not ask for a password before running.
vcgencmd version output that the firmware is dated September 2024.
sudo rpi-eeprom-update output that there was an update available. I ran it again adding -a as the output said to. It output that it was successful.
I ran sudo rpi-eeprom-config -e and typed the changes as listed in the post, did ^S to save and ^X to close out.
Running the first command a second time did not change the output and still tells me the version is from September. eeprom update still tells me there is an update available. eeprom config didn’t actually save the changes.
I went digging in the file system. I have 2 folders for boot firmware, 2711 and 2712 (which I understand to be the latest version). I tried to move 2711 to the home folder, but I got an error that I didn’t have the permissions for that.
After that, I shutdown from the software hoping that it would just change things. And unfortunately it’s back to blank screen with the backlight. So I need to try to cast that spell to make it boot again. Now I’ll be able to prepare for the next time it boots up again.

If you’re seeing the backlight your sd card is most likely booting fine, you’re just encountering the panel failure problem the best way is to reboot. If you get a black screen just wait a bit then hit the power button once hit the down arrow key and hit enter (blind rebooting)
2711 and 2712 are kernels, 2711 is for the CM4&5 and 2712 is just for the CM5 but with a 16k page size. Just leave them alone, by default the CM5 will use the 2712 kernel but if you want to use wine of some other stuff you’ll need to switch back to the 2711 4k kernel on the CM5.

Ok, I’ll give the blind reboot a try next time. Thanks!

I have a uConsole with a CM5 module and I got the standard bookworm image to work, but I don’t have wifi. Any suggestions?
Are you using the stock antenna? If so is it attached to the chassis? Is the antenna connected to the Clockwork main board or the CM5?
Hey Rex, we need to sudo raspi-config to expand the OS on th SD card.
yes. 20 character post minimum.
Stock antenna, attached to chassis (sticking out the top) and connected to the mainboard. It’s a CM5008000. It appears to see the device (lo) if I ifconfig, but no networks ever show up, even if my phone is doing a hotspot next to it.

Your cm5 does not have Wi-Fi, and the cm5 is not wired to access the main boards Wi-Fi. You’ll either have to get a Wi-Fi cm5 or use a USB adapter.

Installed and working great. Thanks Rex. 
Running the lite version with KDE.
I get one item fail during boot.
Looked into it and found the following info:
It’s not causing any issues but just bugs me seeing that red item during boot.
Line 21 is the only line in that file not commented out. Not sure what smartmontools is looking for or if I need it??

Smartmontools is looking for a (P)ATA, Serial ATA, SCSI/SAS or NVMe hard drive. It checks the S.M.A.R.T. data of drives. It failed because you don’t have any in the uConsole, it’s fine.
