SGDMA Interrupt

Hi, I'm having a major issue with the SGDMA component - the callback function that I've defined does not run. I'm not sure whether my code is flawed and I'm not calling the ISR function correct...

This is in burst mode. In continuous mode, the first 32 bit word of data coming from my trigger component keeps getting rewritten. As far as I can tell, this is because the avstream_ready bit toggles for each word the SGDMA writes to memory (which resets my trigger device) - is there any way to keep this bit constant?
