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?
Solved! Go to Solution.

The DMA was broken. For now I'm polling and leaving the DMA for another day.

Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
