Hello @tarekmhnds,

As you are using the Ixora Carrier Board, you do not need the apalis-imx8_mezzanine_can_overlay.dtbo. This overlay is intended to be used with the Apalis Development Board and the Apalis iMX8 Mezzanine.

The reason that the CAN interfaces do not show up is that the default device tree which is loaded is the one for the Apalis Evaluation board.
To see both CANs on the Ixora Carrier Board, you need to select the correct device tree for it.

Therefore, please do the following:

  • Remove the apalis-imx8_mezzanine_can_overlay.dtbo overlay from your overlays.txt file.
  • Set the correct device tree for the Ixora Carrier Board:
sudo fw_setenv fdtfile imx8qm-apalis-v1.1-ixora-v1.2.dtb
  • Reboot the board:
sudo reboot now

Now, both CAN interfaces should show up as be usable from the system.

Best Regards,
Bruno
