ADV7842 detects TMDS clock and that it's locked, but measured frequency is always 0.

Category: Software
Product Number: ADV7842
Software Version: -

Reading data from the IO register 0x6A and HDMI register 0x04 indicates that the TMDS clock is detected and locked, but reading from HDMI registers 0x51 and 0x52 always returns 0.

Any suggestions?


Added other register
