hi !
SDK = ezsdk502(latest)
base board = ti8168
using FBDev sample application to test HDCOMP and SDVENC output.

root@dm816x-evm:/home/video-test#
note : it is ok .output from on-chip-hdmi is ok
in order to test HD-DAC (hdcomp)
root@dm816x-evm:/home/video-test# ./saFbdevDisplay-hdcomp
note : changed
static char display_dev_name[30] = {"/dev/fb0"};
to
static char display_dev_name[30] = {"/dev/fb1"};
but it is not ok ,"NO SINGNAL INPUT" is displayed on the screen connected to ti8168 through HD-DAC interface
in order to test SD-DAC (composite&s-video)
root@dm816x-evm:/home/video-test# ./saFbdevDisplay-sdcomp
note : changed
static char display_dev_name[30] = {"/dev/fb0"};
to
static char display_dev_name[30] = {"/dev/fb2"};
but it is not ok ,"NO SINGNAL INPUT" is displayed on the screen connected to ti8168 through SD-DAC interface
i am sure all the devices are ok
why why why why????????????????????????????????????????
second > try
1.power off base board then power on
2. run the omtb demo
root@dm816x-evm:/usr/share/ti/ti-omtb# ./omtb_dm816xbm_a8host.xv5T decode_scale_display.oms
note : i changed the below in oder to watch video from HD-DAC(HDCOMP) interface
omx setp 0 vfdc OMX_TI_IndexParamVFDCDriverInstId nDrvInstID 1
omx setp 0 dc OMX_TI_IndexParamVFDCDriverInstId nDrvInstID 1
now it is ok
3. in order stop the demo i reboot the board (CTRL + C can not stop it )
4.now how is amazing i operate all the frist steps all are ok
ON-CHIP-HDMI HD-DAC SD-DAC all worked
5. then i power off then power on the board
HD-DAC SD-DAC can not work no picture/video output
why why why why why ???????????????????????????????????????
third > what i want to do is test HD-DAC SD-DAC interface
