We typically suggest that customers evaluate the ADV8005 using the software driver rather than scripts. However, our software driver does not currently support providing input signals on JT6 unless an identical signal is provided on the ADV7842 HDMI input.
If you want, I can send you a script which configures the ADV8005 to receive video on the TTL interface and output over HDMI. Please let me know the details of the input signal (resolution, frame rate, color space) and the output signal (resolution, frame rate, color space).
