I have bases addresses BAR0 = 0xFFC00000, BAR2 = 0xE0000000, and&nbsp; bits settings of register Command/Status (MemorySpaceEnable and I/OSpaceEnable). Inbound window set on CCSR (by default). When reading phys addresses BAR0(0xFFC00000) garbage returns. When reading write data overrides read only registers.
