Hello,

To address the issue with your 10.1" LVDS display on the Verdin iMX8MP with the Mallow carrier board, please consider the following steps:

1. Verify Overlay Application: Ensure that the overlay verdin-imx8mp-panel-cap-touch-10inch-lvds_overlay.dtbo is correctly applied. You can confirm this by checking the directory /proc/device-tree/chosen/overlays. If the overlay file is listed and its value is 0, it indicates successful application.

2. Check Display Connections: Double-check all physical connections between the display and the Mallow carrier board. Ensure that the LVDS cables are securely connected.

3. Test with Weston: After applying the overlay, test the display using the Weston Wayland Compositor. Run the Weston container on your module to see if the display initializes correctly. This can help confirm if the system recognizes the display.

4. Review Display Timings: If the display remains black, review the display’s datasheet to ensure that the timing settings in the overlay match the display’s requirements. Adjust the overlay if necessary to match the horizontal and vertical sync timings.

By following these steps, you should be able to troubleshoot and resolve the issue with your display setup. If the problem persists, further investigation into the software configuration may be needed.

Best regards,

I did this with an Apalis iMX6 and a Ixora Carrier Board and it worked. But I don’t find an example for the Mallow carrier board. Regarding to Toradex sales it should work out of the box. Thanks

If I run the application from Uboot (run m4boot) all seems well, I see “hello world” p…

Hi, @khalil.fourati!

You informed us via email that another Mallow carrier board worked just fine with the display, right?

So I think we can mark this topic as solved, since the issue was hardware-related.
