HDVICP2 in AM3874

Adrian Cox

Other Parts Discussed in Thread: AM3874

Does the AM3874 have the HDVICP2 processor? The feature is missing from the list at http://www.ti.com/product/am3874, but is described as present in sprugz7b (pages 132, 136, 228, 443).

(I'm asking because my u-boot code freezes on AM3874 while waiting for the relevant PLL to lock).

Adrian,

AM3874 does not have HDVICP2 processor. References to it will be removed from our TRM. Sorry for the mistake and thanks for catching it.

Thanks for that. The TRM also shows (Figure 2.6, section 2.10.1.17 and section 2.10.1.37) the DSP and HDVICP PLLs as being present in the AM3874. Is this actually the case?

I've tried using a DM8148 u-boot image on the AM3874, and it locks waiting for PLL initialisation, so I suspect the TRM is also wrong here.

Those PLLs still exist in the device.

However, since you are not using the corresponding IP, you don't need to configure those PLLs.

Thanks - I'll post a second question about our problems with that code, then.
