I am new to the zynq platform and am trying to read from the DDR memory from PL. I do not need to do any writes, just reads. I have been sifting through the forums looking for a solution, and while there are several similar threads, I am still a little confused. I would greatly appreciate an explanation of how this can be done. I am using a ZYBO board, if that matters. Thank you.

You can use the CDMA. There is example driver code that you can use to help you here:

what do you mean stricty from the PL side? Do you mean you dont want to use the processor to configure the DMA?
This is why I suggested the CDMA. It doesnt need the processor. The CDMA is also in the PL too (ie a soft IP)

Yes I mean I can't use the processor to configure the DMA. The example you pointed me to however is C code. I've instantiated a CDMA block, and am unsure exactly how to go about connecting everything up.
