point gray flycapture camera is not working with beaglebone black

hi all,
i have developed point gray flycapture camera preview application in qt5.
it is working in ubuntu. but it is not working on beaglebone black giving error that :
grab loop has an error : Isochronous image transfer is not started.
since the camera preview application from its sdk is working fine (developed on glade) along with the error.

what should i do?

thanks!!
