I am using ADV7612-7511 evaluation kit. I want to connect ADV7511 chip as an independent component and control from my Linux PC. How can I do that?
Thanks in advance,
If you don't want the ADV7612, then you must provide the source data on the video bus-- those are the jumpers I was referring to. You can remove them and disconnect the ADV7612 from the video bus and plug your own source in.
I can't speak to connecting to a Linux PC but you can pull the jumpers on the video bus to disconnect the ADV7612 from the ADV7511 and then plug in whatever you want. There are other jumpers for I2C that you can connect to, but you should be sure the Blackfin on the board isn't doing anything or you will have bus contention. If the Eval board is the "P" version, then it won't be, but otherwise you'll need to type "stoprep" into the terminal to get it to leave the I2C bus alone.
Where is the video coming from?
Which jumper on video bus you are saying? Is the 7612_CSn(29th pin of J3 header)? If I am disconnecting the ADV7612 from ADV7511, then where can I give the HDMI source?
How can I distinguish between a "P" version and the other?
Perhaps I'm not understanding what you are asking. You said you wanted to connect the ADV7511 as an independent component so I assumed you meant that you didn't want ADV7612. What exactly are you trying to do?
There should be a sticker on the board with the part number-- it'll end in P if it is the version without keys.
Thanks for your reply.
Your previous understanding was correct. I don't want ADV7612. As I understood from the block diagram of the EVAL-ADV7612-7511, the HDMI source is given to ADV7612 and its output is taken to ADV7511 as its input HDMI source.
If I am disabling the ADV7612 chip, then from where ADV7511 chip gets its input HDMI?
I disabled the autoboot to the Video processing software and removed all video configuration jumpers. Now I am able to control the ADV7511 chip from my Linux PC. Thanks for your support.
As you said I have checked the sticker on the board to see whether it is HDCP enabled. I couldn't see 'P' on the sticker. So, I assume that it is HDCP enabled. How can I verify it?
The part number on the ADV7612 itself will either be -5 or -5P. How did you purchase it?
