I just got a DevTerm, and i started with installing one of rex’s images of rpi os trixie. The only output that i got was a white screen. I wanted to verify if my DevTerm was broken, so i loaded the official rpi os bullseye from clockworkpi onto it, and it booted fine! Then i tried rpi bookworm from rex, but then i got the same results as with trixie. Why am i getting a white screen on all of the images from rex? Am i doing something wrong? In rpi imager i select the raspberry pi 4 and then i just download the img.xz file and load it into rpi imager. I also tried to unpack the img.xz file, but that also doesnt work. @Rex can you please help me? The original clockworkpi os is way too old to download modern programs, and nothing on there is supported anymore.
On my images because they work with both devices you’ll need to flash the image then go into the config.txt in the boot partition and comment out the uConsole stuff and uncomment the DevTerm stuff.
and it won’t boot without those steps i assume? Thank you very much! I will try it this evening and report what happens. And the uconsole stuff is uncommented by default?
Yes my images are all defaulted to work with the uConsole. So all the DevTerm device tree overlays are commented out. Change that and it should work.
Thank you so much! It works now! Is it still possible to use the thermal printer, or is that a lost feature?
I know it worked with the cm4 under bookworm. Not sure about Trixie I sold my DevTerm a long time ago. You’ll need to install the printer stuff for the DevTerm. sudo apt install devterm-thermal*
Then you should be able to add a printer in the GUI.
what do you mean precisely by adding a printer in the GUI? Because with the original os, you could only print by using a command line. So now i am able to add the printer in linux and print normal images on the thermal printer?
Correct, you can use the add remove printers and add the printer and print images screenshots whatever you want. I had to mess around with the sizing though in the print settings but that’s something you’ll be able to work out. Installing those packages should make it possible. But like I said I had it on the cm4 in Bookworm working. The packages and everything should still work fine with Trixie.
