The DMA is a shared resource.
If you don't have a clear hand shaking between to access it, you might run in to troubles?!.
Additionally, you might as well having caching issues.
I had caching issues while moving data between from one core to the other using the DDR (but no DMA transfer).
Hope this helps.

I'm trying the solution, but I wonder where the dts file is.
I add usb with changing ./project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi
It is petalinux 2018.2,
how to do "altering the devicetree in the boot partition"?
