Hi!
we are working with ezkit-sc589(with buildroot linux add-in). we connected the endpoint(EP) hardware via PCIe to the ezkit-sc589. the application on the sc589(arm core) has access (both read and write) to the EP registers through the pcie mapped memory.this way everything works correctly.
The EP has a DMA engine. we allocated memory on the host via the dma_alloc_coherent function, and wrote the obtained physical addresses to the corresponding endpoint registers. But EP cant read/write data from/to Root Complex(sc589). The same driver code work correct on the x86 platform with the same linux kernel (4.0) .
what should we additionally configure from the sc589 side so that the endpoint has access to the RootComplex(Sc589) memory over PCI?
