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...

I actually just added two FIFOs (my data is 32 bits wide, the internal FIFO on the SGDMA couldn't cope - it was only storing two words, and then writing), which solved the problem. I used one for data (4096 bits deep) and one as a clock bridge (my ADC is clocked to 25MHz, and my DMA and SDRAM run at 100MHz).
