Did you get around to do this for DAC as well? I've looked at Github, but not found it.
I fail to get the DAC irq:s to trigger. I'm using fmcomms2 on a zedboard with no-os driver.
From the register map (Base (common to all cores) [Analog Devices Wiki]) my conclusion was that I should clear
IRQ_MASK register and FLAGS (disable cyclic mode) and that I should interrupts when I queued the next DMA transfer.
Is there anything else I need to do to get the sot and eot IRQ:s from axi_dmac?
