Tool/software: TI C/C++ Compiler
Hi sir,
I am using AM5728 custom board(Referred as Beagle board-X15)(ti-processor-sdk-linux-am57xx-evm-06.01.00.08).
we have connections are AM5728_VOUT1---->GS2962--->through BNC one Monitor we have connected.
in U-Boot Mux_data.h all vout pins added properly.
in Linux kernel command prompt occurs and below command executed.
gst-launch-1.0 -v videotestsrc pattern=snow ! video/x-raw,width=1280,height=720 ! autovideosink
not displayed any thing in monitor side
/etc/init.d/weston stop
after also not displayed any thing
(Actually through serial port i am executing those commands)
because of default output is hdmi output.
how to change those things?
Below things i have added in am57xx-beagle-x15-common.dtsi

display0 = &lcd0;
display1 = &lcd1;;
