TDA4VM: TDA4 RVP camera integration issue with SDK 7.03

Hi,

I have the following issue when integrating SDK 7.03 onto RVP:

Basically I only managed to get camera streaming working for channel #0. It doesn't work for channel #1,#2, etc. I don't know if it is a sensor aliasing issue or something else. I noticed that the UDMA tied to these channels is not receiving the frame completion event, which caused the openVX capture node to wait forever..

Also using the auto-detect, all cameras get detected correctly so it is weird that only channel #0 get streaming video.
The issue can be reproduced with single camera capture application as well. If I select a port number other than port #0, the camera is automatically detected but later the capture process waits forever. 
The issue appeared in SDK 7.03, SDK 7.02 runs fine.
regards,
Victor
