Hello All,
Tarakesh and Iain helped me with compiling the VC3 demo (thank you) here...
http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/116501.aspx#415486
Then I was pulled off onto another task but am now back onto the VC3 port task. When I run the demo, there are errors with the IPC. I searched and saw in another posting Tarakesh asked what the uboot parameters were. So I am being proactive and giving them up front.

So the error has to do with the IPC init process failing. I am going to look deeper, but if someone has already run into this issue and has a clue for me to investigate, then your help would be greatly appreciated. Thanks and have a good day.
