Had similar problems with voltage sag with the LTE modem. Still testing with some new batteries picked up from DigiKey, but sitting at about 50% currently with no shut off.
Actually using Rex’s version of OS this issue was resolved in my case. I was having the same issue in the stock OS and I was suspecting my batteries as well. But now it shows correct battery capacity and shuts down only at 1 or 2%. Otherwise in stock OS uconsole was shutting down between 75-80%

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%

Thank you, I appreciate it!
@Rex Thanks for your efforts regarding the OS on the uConsole!
Do you have any plans on adding your build steps on GitHub?
It would be nice to be able to build the packages/kernels/images without reinventing the wheel. As well as it would open up for easier contributions from your peers!

The kernel is up on GitHub, the userland files for the hardware is in the mega link along with kernel packages. For the Debian images I’m using pi-gen to build them, I just put my repo in and tell it to use my kernel instead of raspberry pi’s kernel. Also just removed a few apps and added a couple. There’s not much to post on GitHub for that.
If you wanna do one just clone the pi-gen repo and build a stock image to see how it does it. It mainly just uses apt to pull all the packages. Change out any apps you want in the scripts and add my repo if you wish for the kernel and userland software.
Pi-gen is real easy, especially compared to yocto. If you run into any problems just send me a DM and I’ll be glad to help.

I just wanted to thank you for all you have done, @Rex! Your work and images have made my uConsole what I had imagined all along, and I also really like your taste in desktop design! I tried installing the Lite version and then installing KDE, but I just could not get iBus working to my liking, so I think I will actually just stick with your setup. Thank you!

@Rex, amazing work. I appriciate your efforts and would like to donate some SATs (Bitcoin) to you, if you would like. Value for value.
Since this morning, I use the last updated lite image and learnt about how Linux and OS works on it. The LTE module works perfectly, and I’m able to use my uConsole as imagined back then when ordered it!
Thanks again, you made it possible for the noobs among us (including me).
P.S. Pop!_OS image works as is (checked via HDMI cable), just kernel tweak is needed. Many users would like it. Pop!_OS maintain privacy and dedicated for STEM students. I’m sure the community would appriciate a flashable image, somewhen, if you ever have a time for this.

One thing I noticed now, @Rex, is that each time I turn on my uConsole I have to uconsole-4g enable.
Could I somehow set it pementatly on, even after powering off? Could you tweak the image to set it on permentatly if once turned on (and off by default at first)?

Ya that will be no problem, I’ll whip up a systemd script to enable on boot for you.

Hello! First of all - thanks for your amazing job, the image is much better than the stock one
But I just meet the DNS issue on 4g only connection.
WiFi only - works great
WiFi + 4g - routes via 4g and DNS works
Only 4g - internet works, I can ping some ip address such as 1.1.1.1, but domain name resolution won’t work.
Do some one have similar issue and\or knows how to fix it?
If I remember correctly, his distro comes with the systemd service to toggle the module. Just systemctl enable the relevant service.
If not, I’m sure he has the .deb for that.

sorry for the beginner question, but where can I find the add / remove software menu?
If I may ask, are you formerly a Windows user? In Linux, typically, adding and/or removing software is done through the terminal, which is Unix (Mac and Linux) -speak for the Windows/MS-DOS Command Prompt.
You’ll want to enter the following for a graphical view of software to add/remove: sudo apt install synaptic. Consider also looking up on how to setup Flatpak.
Better yet, instead of asking here, just do a Google search.

Eh, the thing about Linux is there’s a thousand ways to do anything. I think it’s okay to ask if anyone has a specific recommendation for how to accomplish something.
Synaptic is really powerful and it’s great if you want to remove software, but it can be difficult for new users to discover software there. For installing apps that otherwise can be a bit involved to set up, I’ve been impressed with PiApps.

Thanks for doing this! The update made it possible or at least more easy to use some software I had been hoping to. This is a shot in the dark, but has anyone gotten this release to work with the uPico expansion board (I asked there too, haha)? I suspect something must have changed with device support that confuses the utility meant to manage the board. Thanks!

Has anyone else had issue with the Y axis on the trackball with this image? Immediately lose -y functionality. Cursor stuck at the top of the desktop. Also the screen brightness fn buttons do not seem to be mapped yet. I would love to find a way to make them work. Big fan of this build, so far.
There is a post up in the thread about the mapping the brightness controls. As for the trackball that would be a hardware issue. Have you had this issue with a different image?
