Dear @aymen,

Thank you for contacting us. You should be able to enable the flexcan1 with a change in the device tree according to this article.

 &flexcan1 {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_flexcan1>;
       status = "okay"; 
 };

Best regards

Dear @aymen,

I saw on the community that a very similar issue has arisen once before. You will likely have to alter an iomuxing line. The thread I am talking about is this one.

This is the line you will have to alter:

 &iomuxc {
        pinctrl-names = "default";
-       pinctrl-0 = <&pinctrl_gpio1 &pinctrl_gpio2 &pinctrl_gpio3 &pinctrl_gpio4
+       pinctrl-0 = <&pinctrl_gpio1 &pinctrl_gpio2 &pinctrl_gpio3
                     &pinctrl_gpio5 &pinctrl_lvds_transceiver>;
 
        pinctrl_atmel_adapter: atmeladaptergrp { /* ATMEL MXT TOUCH ADAPTER */

Please let us know how you fare with this approach.

Best regards

Collin

Hello @aymen,

From your logs, it seems that you have edited the imx7s.dtsi file.
Please revert this file back to its original state and edit the imx7-colibri.dtsi file, according to the instructions on CAN (Linux) | Toradex Developer Center.

I have tested the instructions on the page and they work for the Colibri iMX7.

Best Regards,
Bruno
