When the board is a PCIe endpoint, the u-boot pci command responds with “No such bus”. I changed the software by referring to the URL of Enabling ESPRESSObin board as PCIe Endpoint.
PCIe links up, but configuration read/write times out. At this time, the memory of PCIe BAR0/BAR1 can be accessed from the PC(RootComplex).
Eventually I want to access the PC’s memory(RootComplex) from EndPoint, is that possible?
