Hi,
We have DM8148 based customized board. Second is AM3505 based board. We are giving video output of DM8148 to AM3505 as video input. AM3505 requires 8bit BT656 video with embedded sync in UYVY pixel format (720x480 (NTSC)). In hardware we are using VOUT0_G_Y_YC2 to VOUT0_G_Y_YC9 for video output at DM8148. We are using ezsdk_dm814x-evm_5_05_01_04. In software we are using dispaly id 1. In software we configured display for (720 x 480(NTSC)) resolution. We made below configurations.
echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 27027,1440/24/128/128,480/5/41/5,0 > /sys/devices/platform/vpss/display1/timings
echo 1 > /sys/devices/platform/vpss/display1/enabled
echo 0 > /sys/devices/platform/vpss/display1/enabled
echo single,yuv422spuv > /sys/devices/platform/vpss/display1/output
echo 1 > /sys/devices/platform/vpss/display1/enabled
With this settings we are able to get video on AM3505 board but we are not getting proper result. From output it seems that Cr is missing becasue we see the reddish image. For above configurations correct me if I am wrong.
For echo single,yuv422spuv > /sys/devices/platform/vpss/display1/output configuration why we can not configure display1 for UYVY interleaved format.
On DM8148 based board we have design VIDEO SOURCE->DECODER -->FPGA-->DM8148-->FPGA--->AM3505.
To simulate we generate pattern from FPGA with 8bit embedded sync in UYVY format and give it to AM3505 and it display it properly. So path from FPGA-->AM3505 is clear. And we are able to capture-->encode-->dump video and then play it so it plays properly. So there is no problem in capturing so VIDEO SOURCE->DECODER -->FPGA-->DM8148 path is also clear. We are not able to give proper format from DM8148-->FPGA. In short we required 8 bit NTSC resolution on display id1 in UYVY format. Can anyone please help us regarding this.
