ZYNQ7020 USB + DMA

I want to implement USB transmission on the arm side without operating system, and write the data accepted by USB to DDR3 through DMA. How can I achieve this?

Hi Refer to https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842117/Zynq+Standalone+USB+device+driver

we only have USB baremetal driver for device mode, no host mode.

Don't forget to "Accept as solution" or "Kudo" if it helps. Thanks!

@chaoz  Hello, I did not find out how to directly write the data received by USB to DDR3 by DMA, instead of writing to the cache array first and then writing to DDR3 with DMA
