     102This function initializes the CMA channel to start the transfer of a stream of images from an user chbuf (two buffers) to the frame buffer chbuf (one single buffer). The user buffers must be aligned on a word boundary. The CMA component is configured in IN_ORDER transfer mode (blocking when the expected source or destination buffer is not available).
