    What DVSDK version and platform(DM355, DM365, DM6446...) are you using?  Also, where are you getting capture_example application from?  I do not believe this is part of DVSDK.  If you got this from a third party, then is you kernel also from that third party?

    Hi Juan:

    The platform is DM6446, the sensor data are come from FPGA,

    kernel is: linux-2.6.18_pro500, come from: REL_LSP_02_00_00_090.tar.gz

    the capture_example is also come from REL_LSP_02_00_00_090.tar.gz :

    PSP_02_00_00_090/examples/dm644x/ccdc
    [root@VM ccdc]# ls
    capture_example.c  capture_example.h  Makefile

    Thanks.
