Thanks from the kernel log and noticed that your kernel command line

This code wont work. It uses hsrd coded vcan adapter and no physical interface.

From the guthub readme:

Hardcoded to use the vcan0 virtual CAN device.

What does

dmesg | grep -E '(serial|piControl|pibridge)'

print in case of failure and after a successful reset?

The ConCan has just a power LED. The other LEDs are not populated (it's a standard enclosure for our extension modules thus all 6 leds are cut out).

How did you try to use the CAN interface?

The other sos report also contains

enable_uart=1

in /boot/firmware/config.txt?

Codesys sp21 isn't supported yet. We will release a beta version of the library with sp21 support in the next days.

Bwfore bookworm the kernel header package is called raspberrypi-kernel-headers.

The device is available as can0. You can list the connection parameters with the same tools you would use for an ethernet adapter (eg. ip link show, ...)
