Other Parts Discussed in Thread: SN65DSI86, TEST2
We are validating our DP monitor with the SN65DSI86 EVM by configuring for Test Pattern output but nothing is being displayed on the monitor.
Below is the process we are performing:
1. TEST2 is high(SW2-7 is OFF).
2. HPD pulled high to 1.8V.
3. Using Aardvard executed "ASSR Disable" script then "Test Pattern" script(see scripts below).
How do we configure the SN65DSI86 for stand-alone Test pattern generator for 1080p60?
Stand-alone meaning that there is no DSI connection. i.e., no DSI clock.
Thanks,
Tim
