@Rex were you aware that floppy drives are compatible with your build?

No, but it doesn’t surprise me that’s it’s in the kernel still. That floppy drive is almost as big as the uConsole.

Hi @Rex
I think i might have found an issue with the audio when trying to drive sound over a set of USB headphones from the USB A port.
This is when using a CM5
The sound is extremely quiet even when cranked to max volume, is this expected?
Thanks 
EDIT: I was able to use fn+shift+vol keys to increase the volume but to listen at normal volume there is a large ammount of distortion in the audio as if increasing the volume is only setting an overdrive.

The max output on the stock USB lanes on the uConsole is 6w. What are your headphones rated for? If they are 10-15w then you wont be able to get the max volume out of them.

Thank you so much Rex! I have just upgrade kernel to newest one v6.12.21. Everything runs so smooth! The only thing is still a problem on my uConsole CM5Lite is the Orange Led does not light up when charging. I got it lighting up when in kernel 6.12.17 even when I shut the machine down. I don’t know what special I installed into firmware, until then the orange led does not light up anymore even I re-install kernel .17 above. Much appreciated, Rex!

Are we safe to update or should we avoid doing so to avoid breaking things?
default updates via sudo apt update && sudo apt upgrade are safe
if you somehow overwrite custom kernel – it will die as uconsole requires custom kernel. but it generally out of normal usage.

You can update normally and you’ll receive my kernel updates just like a normal RPi OS install.
If I can’t boot from SD card, how am I supposed to change the eeprom settings in raspi-config on my CM5 Lite?
You can boot the CM5 in a IO board to make the changes, or try a few different SD cards to find one that works. Smaller are more likely to work and you only have to use that SD to make the change. The EEPROM changes will stay with the module so you can switch back to a bigger SD.
I was able to get it booting off an SD card after using the bootloader update utility image from RPi imager to get the latest version

That’s good to know.
Hi Rex,
I have a quick question i wanted to ask, I use a CM5 Uconsole and ive ran into an issue when charging.
When I have a low battery level if i start charging device whenever I open an application it will take itself off charge for some reason, once i get above 50% it will be fine.
When this happens i can hear a squealing noise which i think is coming from the voltage regulator
I use x2 fogstar 4000mah batteries.
Could there be any reason for this? How can I get around the issue or is it just a byproduct of using the higher power draw of the CM5?
Thanks in advance

I tried to compile the latest kernel from Rex’s github repo on my ubuntu 24.04
here is the steps:
export CROSS_COMPILE=aarch64-linux-gnu-
export DTS_SUBDIR=broadcom
export IMAGE=Image.gz
export KERNEL=kernel8
make O=build bcm2711_defconfig
scripts/config --file build/.config --set-val CONFIG_WERROR y
make O=build -j 2 $IMAGE modules dtbs
but met an error

What are these error?
Here’s how I cross compile it
git clone --depth=1 https://github.com/ak-rex/ClockworkPi-linux
cd ClockworkPi-linux

I had the same issues but managed to fix with an older and smaller sized card.
Once it booted and i can verify that via a second screen i was able to finish the firmware update.
Also note that in case it fails there’s a fallback img from the RPi foundation that reverts the firmware version.
I think there might be a way to use that directly to have it force flash the newest good version.

Yeah, I have a smaller Samsung Evo card being delivered today that will hopefully work better. Was looking at my unused cards are realized I only have Sandisk Ultras
wait… i know i’m an idiot… but can I just order a CM5 and put it in my uConsole (when i get it) or my DevTerm (with CM4 board) ???
