DMA Locked Core

I'm looking at the dma_intr example project for the UltraZed board.  It seemed like a good way to learn how to configure the Zynq for DMA and it probably would be except that the Zynq processing core is locked.  That makes it a little difficult to see how to set up the core to perform DMA.  Considering that it's a free example, I didn't expect a ton of documentation explaining every aspect of the design but why try to obfuscate an important part of the project?

And another thing, since the

And another thing, since the core is locked and the output products are not up to date, I cannot update the core or synthesize the project.  Kind of limits the usefulness of the example.

Hi there,

Hi there,

can you be more specific on which example you are referring to?

I am unfamiliar with a reference design called dma_intr. Where did you get the example from?

Thanks!
