Other Parts Discussed in Thread: TVP7002

Hi.

5706.loggerSM.log

ezsdk 5.05.02.00

psp : 4.04.00.02

we use a custom-board without tvp7002 and through FPGA display decode/encode.

I received HDMI data through th FPGA, display through HDMI and FPGA.

when played through hdmi in 1080p/720p/480p resolution it work well done.

The problem is that change 'display_id=1(DVO2) ' hang on semaphore pending for scaler component.

please advise what could be the problem.

thank you

Hi aupers,

I think that the display_id parameter was added to display to the LCD present in the DM8148-EVM, is the only place where I have tested it.

Not sure which is the problem in your application but if your goal is to show the same content in both, HDMI and DVO2 you can try to tie the outputs and put you application to display just through HDMI, then the hw will handle the DVO2 display as well, something like:

echo 0 > /sys/devices/platform/vpss/display0/enabled || true
echo 0 > /sys/devices/platform/vpss/display1/enabled || true
echo 0 > /sys/devices/platform/vpss/display2/enabled || true
echo 5 > /sys/devices/platform/vpss/system/tiedvencs || true
echo 2:hdmi,dvo2 > /sys/devices/platform/vpss/graphics0/nodes || true
echo vcompmux:hdmi,dvo2 > /sys/devices/platform/vpss/video0/nodes || true
echo 1 > /sys/devices/platform/vpss/display0/enabled || true
echo 1 > /sys/devices/platform/vpss/display1/enabled || true
echo 1 > /sys/devices/platform/vpss/display2/enabled || true

Another option is to use gstreamer to do it, however we haven't tried capture 480p with the Ridgerun SDK, likely the omx_camera plugins needs some modifications but if you already have a pure OMX based application doing it, it should be pretty straight forward to port the changes to omx_camera.
