Hi ,
I'm using DMAI example video_display to test BT601 output interface .
Below command line I'm using :
./video_display_dm368.x470MV -y14 -O lcd
It failed when open devices , I saw errors on dmesg:
...
Start of logicpd_encoder_setmode ...
Invalid id ...
...
so I modified below codes :
vid_encoder_types.h , changed definition of VID_ENC_STD_640x480 from "640x480" to "VGA"
and ,
package/ti/sdo/dmai/linux/display.c , changed Display_Attrs_DM365_VID_DEFAULT :
Display_Output_COMPOSITE --> Display_Output_LCD
ColorSpace_YUV420PSEMI --> ColorSpace_UYVY
After above , I ran test command again , however nothing was captured on VCLK/GIO79 or VSYNC/GIO83 .
Can someone point out what else should be done to see waves on VCLK/GIO79 and VSYNC/GIO83 as my first step of BT601 output debug ?
BTW , I'm using ti_dvsdk_dm368-evm_4_02_00_06 and dmai_2_20_00_15 .
BR ,
Paul
