Environment:  iMX6, Qnx 6.6

We are developing driver for SPI Slave in iMX6 with DMA using DMA library (libdma-sdma-imx6x.so) provided in BSP. 
Initialization for DMA and SPI is done accordingly. (Peripheral to Memory and vice versa)
During DMA initialization we attached the flag attach_flags=DMA_ATTACH_EVENT_ON_COMPLETE.
We are getting an event when the DMA transfer is completed and works fine as expected.

Now the problem is:
Our project need is to have the driver as library. So we created SPISlave.so and this in turn includes the DMA library 
libdma-sdma-imx6x.so.
Now we are not receiving the event DMA_ATTACH_EVENT_ON_COMPLETE.
Should we do anything more to receive the events if we have the driver as .so?

/************** Readme.txt **********************************/
Supported Attach Flags:
	DMA_ATTACH_EVENT_ON_COMPLETE =	0x00000010,	/* Want an event on transfer completion */
	DMA_ATTACH_EVENT_PER_SEGMENT =	0x00000020,	/* Want an event per fragment transfer completion */”
