hi
i design my tvp5158 board for dm365.i read part of udworks dvr reference design.i find dvo_A[0:7] connect to dm365's CIN[0:7] and dvo_B[0:7] connect to dm365's YIN[0:7].
like this
In my mind,i think it is wrong.it should be that dvo_A[0:7] connect to dm365's YIN[0:7] and dvo_B[0:7] connect to dm365's CIN[0:7] according to dm365 datasheet and tvp5158 datasheet.because
1,Primarily ,dvo_A port outputs muxed video data ,and dvo_B port only is used by 2ch-D1 mode and 16-bit bt.601 mode
2,dm365's YIN[0:7] receive time-multiplexed 8 bit on lower channel and Y data on 16bit mode.
3dm365's CIN[0:7] receive time-multiplexed 8 bit on upper channel and C data on 16bit mode.
i read dm365 datasheet and find YIN and CIN could be swap according to CCDCFG register's YCINSWP bit.So,
my first question is
does tvp5158's dvo_A [0:7] connect to YIN[0:7] of dm365?does mcvip driver should be revised if tvp5158's dvo_A connect to YIN of dm365?
my second question is
i don't want to connect intreq of tvp5158 with dm365's gpio because my dm365 gpios is used up.in this case,should mcvip be revised?in my mind,intreq is not need in mcvip because mcvip don't use interupt mode to receive video data.
Am i right?
could any experts on forum light me? i am appreciated.
thanks
