We are in urgent need to get VPIF raw capture mode working. As I understand, there are several steps involved in setting those registers correct. However, after we setup those registers, no data is captured even everything is seems setup correct. I am wondering someone can point out the problems or missing steps here:
Steps to setup Channel 0 and Channel 1 in Raw Capture Mode:
1) Disable VPIF_ChCtrl0 and VPIF_ChCtr1,,
2) Setup VPIF_ChCtrl0 and VPIF_ChCtr1
3) Setup SDRAM address to Ch0_TOP_Y_STADR
4) Enable VPIF_INTEN, set VPIF_INTERSET, clear VPIF_INTERCLR
5) No need to setup VSIZE_CFG, HSIZE_CFG
6) Setup VSCLKCH0 to external trig
7) Enable both VPIF_CHCTR0 and VPIF_CHCTR1
those settings should have v_Sync as the interrupt source shown in VPIF_INTEN when changes status.
We see VPIF_INTEN flops, but no data is captured.
We needs some example codes in CCS to make this working. Please help! Thanks.
