Entering in free run mode when I switch between 2 video souces

Hi,

I saw in the manual (Rev C) page 192 "Internal parameters, e.g. the threshold for entering free-run mode, can be overwritten by
internal parameters. Contact ADI for further details, if required."

  Also, please check the register mentioned below in order to switch into and out of free-run mode. This threshold register is described on page 193 of the document at ADV7181C_Manual_RevC.pdf

Thanks,

Poornima

Thanks for your quick answer. I saw in register 0xB3 there are also reserved bits.

Hi,

The default threshold value is set in register 0xB3. The threshold can be enabled or adjusted as required by using 'CP_F_RUN_TH' register.

Thanks,

Poornima

Hi, I tried several values as default value b100 and max value b001. But I have the same issue. I didn't see how to disabled it. Is it in "reserved bits"?

Hi,

 Could you please try by disabling the freerun by configuring the 'Disable SDP freerun mode and Bypassing the CP'.

Thanks,

Poornima

Hi,

I am working with CP not SDP. Is it possible to disable freerun in CP?

Bruno

Hi,

  Please bypass the CP for disabling the freerun.

Thanks,

Poornima

Hi,

To be sure to undersand your answer, I need to set (value 1) the bit [0] in register 0xC9. Can you confirme?

Regards

Bruno

Hi,

  Yes, Please check and let us know whether CP module get bypassed.

Thanks,

Poornima

Hi Poornima, sorry for the delay but I had an issue on my board.
I need to order an evaluation board to continue my investigations.
I will send you news when I will receive it.
Regards

Hi Poornima, I am working now on the Evaluation board from ADI (EVAL-ADV7181CLQEBZ) to solve my issue. I tested your answer : to set bit 0 in register 0xC9 but I have the same issue.
Do do have an other idea?
Regards

Hi,

  Apologies for the delayed response.

  Please use below register for disabling the free run and let us know the result.

Thanks,

Poornima

HI,

We have the same issue.
But we use the Component Processor, not the Standard Processor.

Hi,

  Please evaluate the same in our eval board by configuring the above suggested freerun registers and let us know about it.

Thanks,

Poornima
