Channel A and B configuration on DM642 EVM

Started by "Harsha, Manjunatha (IE10)" March 21, 2006
Hi,

I have to configure the channel A and B of Video port1 of DM642 (720MHz)
EVM, for capture.

The Video port1 is connected through TVP5150 Video Decoder on DM642 EVM.

I am using "ntsc.pjt" as a reference project.

I have made following things to configure,

I have enabled DCHNL bit of VPCTL register and DCDIS bit is made 0 in
VPSTAT

register.

capChan2 = FVID_create("/VP1CAPTURE/B/1", IOM_INPUT, &status1,
(Ptr)&EVMDM642_vCapParamsChan2, NULL);

FVID_control(capChan2, VPORT_CMD_EDC_BASE + EDC_CONFIG,

(Ptr)&EVMDM642_vCapParamsTVP5150_1);

FVID_control(capChan2, VPORT_CMD_START, NULL);

FVID_alloc(capChan2, &capFrameBuf2);

Control is not coming out of the "FVID_alloc" API.

So I am not able to configure the video port for channel A and Channel
B.

If you have already did the same on DM642 EVM could you please give me
some reference

things so that I can use it to do the same.

Thanks and Regards

Harsha
