Hello Rupesh,
Thank you for reaching out with your question about enabling HDCP on your iMX8M Plus and ADV7613 setup. Let’s address your concerns step by step.
-
Checking HDCP Encryption:
- To verify if your input stream is HDCP encrypted, you can use a protocol analyzer that inspects HDMI signals. This tool will indicate whether HDCP is active. Additionally, some HDMI sink devices, like the ADV7613, may have status registers or logs that show HDCP status.
-
Enabling HDCP on iMX8M Plus:
- Ensure that the HDMI output on your iMX8M Plus is configured to support HDCP. This typically involves enabling HDCP in the HDMI driver settings. You might need to adjust the device tree or driver configuration files to activate HDCP support.
- Verify that your software stack includes the necessary HDCP libraries and support. This might require a specific version of the Linux kernel or additional software packages.
-
Potential Missed Steps:
- Confirm that all HDMI cables and connections are HDCP compliant, as non-compliant components can disrupt HDCP functionality.
- Make sure the ADV7613 is configured to accept HDCP-encrypted streams, which may involve setting specific registers or configurations.
- Check for any firmware updates for both the iMX8M Plus and the ADV7613 that could address HDCP issues.
By following these steps, you should be able to diagnose and potentially resolve the HDCP issue. If the problem persists, reviewing the documentation for both devices to ensure all configurations are correct might be helpful.
I hope this helps you get HDCP working on your setup!
Best regards,
