Hi,

I tried to run saLoopBack example. But, when I try to stop load-hd-firmware.sh, I have this :

And then, when I run saLoopBack, I have this:

root@dm814x-evm:/usr/share/ti/ti-psp-examples# ./saLoopBack
Driver Name: ti81xxvin
Driver bus info: TI81xx Platform
Driver is capable of doing capture
VPSS_DCTRL: venc 1 already stop
saLoopBack:
 Mode set is 0
Setting DV Preset failed

Is there a step I did not do before?

thanks in advence !

    Hello,

    Please try:
    cd /usr/share/ti/ti-media-controller-utils/

    /etc/init.d/matrix-gui-e stop
    /etc/init.d/pvr-init stop
    ./load-hd-firmware.sh stop
    ./load-hd-v4l2-firmware.sh start
    ./saLoopBack

    hi Margarita and thank you for your replay.
    I already tried these but had the result mentioned above

    Hello,

    Regarding this error:

    " Mode set is 0

    Setting DV Preset failed"

    Please check IO expansion board is connected properly, because setting/querying of DV preset fails means its not able to detect the input source.

    Please check this wiki page also:

    "Capture source must be connected to the component input of IO EXPANSION board before run the sample application, otherwise the sample application reports error."

    Hi Margarita,

    I check component input of IO EXPANSION board, everything is OK but I have the same result above. I use composite video input of expension borad and want to display DVD output to LCD.

    In the boot stage, I have following error :
