Dear *,
we have setup of host standard PC as RC connected to J721S2 device over PCIe. In a previous project we had Xilinx FPGA connected to PC over PCIe.
There is an option in Xilinx XDMA that DMA descriptors can be fetched dynamically over PCIe. In other words there is no need to manually copy DMA descriptors from host PC (RC) to device memory (EP).
Is it possible to use UDMA with PCIe the same way? Or we have to make two steps. First copy descriptors to device local memory and then in a second step use it to transfer data over PCIe?
Best regards,
Dubravko
