AM3874 HDVICP2 module behaviour

Other Parts Discussed in Thread: AM3874

Hi,

I would like to know DHVICP2 module behaviour.

Please see the below.

This is a part of log file of AM3874/DM8148 booting Android OS.

As you see from the above list, there is different behaviour between of DM8148 and AM3874. In DM8148 log, IVDH0 (HDVICP2 module)  process is going well, and this system boot up without no problem. But in AM3874 log, IVDH0 process is not going well,  this system can not boot up. The difference of both system is only device!

DM8148 system is used DM8148ES device. AM3874 system is used AM3874 production device. I think HDVICP2 module is not inculded in AM3874 or its module is disabled. But it seems that some data is returuned from AM3874. But its returned data is not same as DM8148ES device.

Is HDVICP2 module of AM3874 really disabled?

Please let me know.

I appreciate your quick reply.

Best regards,

Michi

    Michi-san,

    AM3874 device does not have HDVICP2 module/subsystem.

    I have checked:

    1. AM3874 datasheet - no HDVICP2

    2. AM3874 TRM - no HDVICP2 chapter

    3. AM3874 official product page - http://www.ti.com/product/am3874 - no Video Acceleration (HDVICP)

    4. E2E forum, see the below threads:
