Got it! How I can achive it with a "user patch"?

Meanwhile I adopted linux-current-rockchip64.config in build/config and build the system with comedi drivers included. Hope it will work. My be the way I couse is not optimal but that's what I could figure out so far. Any help still appreciated. Thomas

The most resent build 24.5.0-trunk.93 does not have comedi drivers included. I tried to build them with the armbian build system, but it is exclude there. How I can change that so that I can include these drivers. I have a bunch of data aquisition system relying on this drivers that I ran with a rockpi 4c+ Any hint appreciate, Thomas

after uninstallation and re-installation of kernel headers things work now! Thank YOu!

I installed the image, then sudo update -> upgrade, then armbian-config->install headers -> ls -l /usr/src/linux-headers-5.15.93.... so, do I have to reboot and then install the headers from within armbina-config?

armbian-config -> wrong kernel (old 5.15.93!) current ist 6.1.50!! (uname -a)

I got it working in Armbian_23.8.1_Rockpi-4cplus_jammy_current_6.1.50_i3-wm_desktop.img.xz but not yet in bookworm

Thank's. I am going to try.

I use Armbian_23.8.1_Rockpi-4cplus_bookworm_current_6.1.50_xfce_desktop and need the current headers but could not find them sudo apt search linux-headers do not show them. I need them for the procedure described here https://github.com/glasgowneuro/comedi_raspberry_pi_bullseye/tree/main in order to install missing kernel drivers (comedi usbdux-sigma) Can anyone help please!

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

Where can I get the kernel headers for rpi4b for 5.15.92-bcm2711? sudo armbian-config does not get it

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

tried the same procedure with armbian bullseye current version and tried to compile the files form raspberry pi (Bernd Porr) this is the result root@rockpi-4cplus:/home/ts/usbdux# ls -l /usr/src/ insgesamt 4 drwxr-xr-x 24 root root 4096 8.

no sudo apt install linux-firmware-free is not available on the system
