    DMA debugging


      I have an analog front end working, feeding a DMA transfer into a filter block.  I never see a DMA request coming out of the filter block.


      I have pins attached to the SAR EOC which is also died to the DMA DRQ, and to the filter DMA_REQ_A.


      I have activity on the SAR EOC, but nothing on the DMA_REQ_A pin.


      The peripherals are started, and I used the DMA wizard to generate the code for the DMA.


      How can I figure out if it's the DMA that's not happening, or the filter?
