DS90UB949-Q1EVM: HDMI Status Monitor

Part Number: DS90UB949-Q1EVM
Other Parts Discussed in Thread: ALP

Hello, TI team:

I get a DS90UB949-Q1-EVM now and I want to check the HDMI input status before I get DS90UB948-Q1-EVM, and I have following problem:

1. I link the DS90UB949-Q1-EVM by ALP:1.57.0010 and it works well, for example read/write registers.

2. Now, I connect a HDMI source from laptop and clock rate around 74MHz (1280x720), origianally, I expect I can observe some HDMI information, for example. Fig-1 & Fig-2.

    Linked video source : No & HDMI Freq. : Not Stable. (I measure this waveform and it is good.)

3. I just want to confirm: The HDMI monitoring flag will work normally after linking success between Serializer and De-serializer?!
