I didn’t upgrade 4g firmware so mine shown as ttyUSB2
. And I had to restart ModemManager in order to get 4g module showing up
To report back: updating the old installation to the newer kernel and firmware worked, and it’s running on a CM5:
Regarding the screen I found something to look into, as it depends on the CPU frequency if it will work on boot or not. If the minimal frequency is set to 600MHz the screen will turn on but always stay blank, if it is set to 1000MHz or above it will work. The PC is working fine with 600MHz, only the screen isn’t.
I had the CM4 running with a 100MHz minimum without issues, but I’m not sure if the CM5 even boots with that, or if initial_turbo is even working and it just takes forever.
Now we just have to get the sound working somehow.
Does it reliably boot every time for you? The screen currently fails to start about 20% of the time.
I’m runnung my CPU at 2900 and GPU at 1000.
Yes it boots every time, but only if I have the arm_freq_min above 600. But the screen only works if arm_freq_min is above 1000 or so. The screen never works with very low cpu speeds, but it almost always works with higher ones, I tested it quite a few times to make sure. So something must influence that.
My max cpu speed is at 3000 without issues, also under full load, and it stays nice and cool.
I also changed the governor settings so it throttles down better if there is not much going on. With the CM4 it was at around 200MHz most of the time. But the CM5 doesn’t boot with super low clock speeds for some reason, I haven’t looked into why that would be yet.
I tried setting the arm_freq_min=1000
and it seems to have no effect on the screen failure rate. It failed to display a image on 1 of 10 cold boots. arm_freq_min=1500
is the default.
What do you have for the overclock listed in config.txt I’ve only got it to be stable at 2800.
Yes, at 1000 it works, but at 600 the screen wouldn’t work anymore, at least when I tested those two values. I can try again now that I have set everything up fully.
For the 3 GHz I had the same over_voltage_delta as you at 50000, that’s all it needed. But now I’m running it slower again, it’s still much faster than a CM4 at 2.1 GHz.
try shutting down and booting 10 times and let me know if you get any screen fails.
Well, that’s interesting: Now that the uConsole is nice and warm from using it I set all clock speeds to the default and did 10 shutdowns and boots to test the screen. The screen only worked twice out of 10.
I have done 10 more, and it worked 50% of the time. So still very inconsistent.
It averages about 20% fail rate.
Maybe there are slight differences in the modules or screens, but it barely works 50% of the time for me now.
That’s weird, have you gotten any power supply warnings yet overclocking? I’ve got 1 so far but that was running a benchmark.
Hi I’d like to do the compiling myself. Do you or anyone else happen to have a updated 001-patch file? Im stuck there as the original one doesn’t work with 6.6y kernal.
Here you go, I just made a patch for you that’ll work with 6.6.y.
6.6.y kernel patch
i cannot get this to work i did image and nothing coming on the screen green light is on
What device are you using?
If it’s a DevTerm you need to edit the config.txt to work with the DevTerm, instructions in the config.txt.
If you’re using the uConsole is it CM4 or 5? If CM4 did it work with the official distro?
Soon to be new uConsole owner I wanted to put my best foot forward and say Thanks for your service and the work you are doing on this as well. I myself am a retired Air Force vet trying to stay on the cutting edge of these things so I appreciate all your hard work. - Brian-
Been running your image on my uconsole with its cm5 all weekend, and besides temps its seems fairly usable, kind of a handwarmer. I have to do this reboot a few times and full power down then reboot to get it to boot. If you can`t get it working try rebooting it a few times before you give up!
Hi everyone!
I would like to ask a question about compiling a kernel module with Linux kernel 6.6.y provided for this distribution (which I installed updated recently).
In order to compile, in this case, a Realtek driver, the guide advises me to use DKMS, but it requires the kernel headers (or source code) for compiling. No default repo contain compatible headers and I tried giving to DKMS the kernel source folder but without success (the main problem is that DKMS tries to find kernel headers in /var/lib folder, skipping given --kernelsource argument, and it doesn’t find them).
Did any of you perform a kernel module compilation with this kernel? Thanks in advance!
the kernel headers are already included they’re located here /usr/scr/KERNEL_VERSION
