Hi,

I have new DM368 EVM and created the SD card with DVSDK 4_02_00_06 and put the card and power on . I can see the boot steps on UART teraterm, on LCD Linux logo and then TI logo able see but Matrix Gui is not all coming. On teratem, able to login as root and can see all the files.

Please let me know if any issue on the SDK or hardware.

Waiting for your valauble feedback.

Regards,

Vageesh K M

    hi,

    Finally MAtrix Gui coming on LCD after connecting the camera module to EVM (but nowhere its mentioned that this is compulsory) but still examples of Encode/Decode not working.

    Expecting some issues in the bootargs as i am connecting external TV to composite port and clicking the Decode example, its showing the start demo screen on TV but coming out after clicking start demo button.

    Please share the correct bootargs to be set for this setup. here mentioned the default boot.cmd from sd card created with mksdboot.sh script.

    mmc rescan 0
    setenv bootargs 'console=ttyS0,115200n8  root=/dev/mmcblk0p2 rw ip=off mem=60M video=davincifb:vid0=OFF:vid1=OFF:osd0=480x272x16,4050K dm365_imp.oper_mode=0 vpfe_capture.interface=1 davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=480x272 rootwait'
    fatload mmc 0 80700000 uImage
    bootm 80700000

    Thanks,
