Hello!
If you’re encountering issues with a DSI display on the Verdin AM62, here are some steps you can take to troubleshoot and resolve the problem:
-
Device Tree Configuration: Ensure that the DSI node is enabled in your device tree configuration. This is crucial for the display to function correctly. You can do this by setting the status to “okay” in the device tree:
&dss { status = "okay"; }; -
Kernel Configuration: Verify that you are using the correct Linux kernel version. The Verdin AM62 supports Linux kernel version 6.6.53 with the toradex_defconfig. This ensures compatibility with your hardware.

Troubleshooting the tc358768 Bridge:
- Ensure there are no conflicting display overlays enabled in
/boot/overlays.txt. - Enable debug prints in your display driver to trace initialization steps. This can help identify where the process might be failing.
- Use
ftracefor detailed diagnostics of driver loading behavior, which can provide insights into any issues during the driver initialization.
Further troubleshooting tips.
- Ensure there are no conflicting display overlays enabled in
If the issues persist after these steps, double-check that your DSI configuration aligns with the reference design specifications for signal routing and termination.
I hope this helps resolve your display issues. If you have any more questions, feel free to ask!
