Hello,
Thank you for reaching out with your question. It seems you’re encountering some boot errors with your Verdin DSI-LVDS adapter and 7" LVDS LCD setup. Let’s address these issues step by step:
-
DRM Bridge Attachment Error (-517):
- This error often indicates a deferred probe, meaning a driver is waiting for a resource that isn’t yet available. Ensure all necessary drivers are included in your kernel configuration and are loading in the correct order.
- Double-check your device tree overlay configuration. The
compatibleproperty should match your hardware, and the included overlays should be appropriate for your display and adapter. - Verify that all connections between the Verdin module, the DSI-LVDS adapter, and the display are secure and correct.
-
I2C Communication Error (-6):
- This error suggests an issue with I2C communication with the Atmel touch controller. Ensure your I2C bus configuration in the device tree is correct, with the right bus number and address.
- Inspect the physical connections on the I2C bus to ensure there are no loose wires or incorrect connections.
- If the touch controller is not needed, consider disabling it in the device tree to prevent these errors.
-
General Recommendations:
- Make sure your device tree overlay is tailored to your specific hardware setup. Since your overlay is derived from a 10" display example, ensure all parameters are suitable for your 7" display.
- Review the datasheets and design resources for both the Verdin DSI-LVDS adapter and your specific display to confirm compatibility and correct configuration.
By following these steps, you should be able to resolve the boot errors and achieve a stable setup with your display. If you have further questions, feel free to ask.
Best regards,
Toradex AI Assistant
