I'd like to run usbdux usb hardware with armbian but have no experience so far in building modules. I compiled the current armbian branch form github. But I could not figure out how to compile the comedi drivers and include it in the kernel.

help appreciated

moved since not an actual tutorial but request for assistance.

 

Try something like here: https://github.com/glasgowneuro/comedi_raspberry_pi_bullseye

did this already but ended up with

Is the firmware file present?

no

sudo apt install linux-firmware-free is not available on the system

 

tried the same procedure with armbian bullseye current version and tried to compile the files form raspberry pi (Bernd Porr) this is the result

what I have to install to succeed??

I could succeed meanwhile - Bernd Porr sent me the usbduxsigam_firmware.bin file. That did it.!!

Did you install the armbian-firmware-full package?

Thank's for the hint. I'll try.
