Hi, all.

After system boot I tried to load ti81xxvin.ko and got messages :

root@dm816x-evm:~#

syslink kernel driver module,M3 BIOS Firmware binary and VPSS kernel driver module are loaded during system boot, so all prerequisites for loading ti81xxvin.ko has beenmet.

Any propositions?

Thanks.

    Gregory,

    Could you try below when loading vpss.ko

    insmod vpss.ko i2c_mode=1

    Regards,

    Hi,

    You cant run open max and V4L2 capture together. This is because openmax requires I2C to be accessed from media controller and V4L2 capture requires same I2C instance to be accessed from A8 Linux. So you have to select either of them. Further you need to insmod tvp7002.ko before loading ti81xxvin.ko.

    Regards,

    Hardik shah

    Hi, yihe.

    Hi, Hardik.

    Below line from load-hd-firmware.sh script

    modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60,dvo2:1080p-60,hdcomp:1080p-60 i2c_mode=1

    i2c_mode is set to 1.

    Next, I removed /etc/rc5.d/S99-matrix-gui-e. And I load tvp7002.ko before ti81xxvin.ko.

    Problem persists.

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/152894.aspx#554794 - can this post resolve my trouble?

    Hi,

    For V4L2 capture you should not be using load-hd-firmware.sh. You should refer to following userguides. load-hd-firmware.sh is for SDK. SDK doesnt support V4L2 capture and display as of now.

    http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Video_Capture_Driver_User_Guide and http://processors.wiki.ti.com/index.php/DM816X_AM389X_VPSS_Video_Driver_User_Guide_PSP_04.00.01.14

    Hi

    ti81xxvin.ko successfully loaded by using load-hd-v4l2-firmware.sh and dm816x-hdvpss-v4l2.xem3 instead of  load-hd-firmware.sh and dm816x-hdvpss.xem3. This files located at /usr/share/ti/ti-media-controller-utils of  target filesystem, prepared by SDK installer.

    Hi Gregory,

    thank you for your solution. Bash commands tweaking rc to insert ti81xxvin.ko each time system loads

    cp /usr/share/ti/ti-media-controller-utils/load-hd-v4l2-firmware.sh /etc/init.d/
    cd /etc/init.d
    cp load-hd-firmware.sh load-hd-firmware.sh.old
    cp load-hd-v4l2-firmware.sh load-hd-v4l2-firmware.sh.old
    cp load-hd-v4l2-firmware.sh load-hd-firmware.sh

    Does TI provide something more sophisticated then interchanging files?

    Regards,

    Jacek
