dm365 EVM TV interface does not output

Other Parts Discussed in Thread: TMS320DM365

Dear all:

             I run dvsdk_dm365-evm_4_02_00_06_setuplinux in the board DM36X EVM (REV F), I run demo encode、decode in the directory dvsdk-demos_4_02_00_01 by  pal capture, TVOUT interface ouput normal, but i run  demo video_loopback_resize in the directory dmai_2_20_00_15(I added video_loopback_resize_dm365.cfg file),TVOUT interface does not output.boot args set as below:                 

setenv bootargs console=ttyS0,115200n8 rw mem=54M video=davincifb:vid0=OFF:vid1=OFF:osd0=720x576x16,4050K dm365_imp.oper_mode=1 davinci_capture.device_type=1 vpfe_capture.cont_bufsize=6291456 davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=pal root=/dev/nfs nfsroot=192.168.2.182:/home/gjpan/targetfs ip=192.168.2.193

                          run param list as below:

#define DEFAULT_ARGS { VideoStd_D1_PAL, 0, TRUE, TRUE, FALSE, FALSE, 0, 0, \
    0, 0, -1, -1, -1, -1 , Display_Output_COMPOSITE, Capture_Input_COMPOSITE}

                           demo video_loopback_resize can run normally ,but TVOUT interface does not output . I run demo video_display in the same directory ,does not output too.  who can tell me why ?

 

  • when you run the above apps, what do you see on display device?

  • Hi ,nagabhushana,

                    Many thanks for your reply,TVOUT interface always displays as below until stop running video_loopback_resize_dm365-
    nor.x470MV.

    In the passing case, can you provide a screen-shot?

  • Hi,nagabhushana:
     
                Thanks,TVOUT can output by cat /dev/zero > /dev/fb0,fb1
  • excellent! glad to know that.
