, configuration mechanism #1 is the only option to access the PCI configuration space. The RW software can read the mcfg base address: Figure 1 At the same time, we can also see the value of b0d2f0's register: Figure 2 then, based on the base address f8000000 and b0d2f0, according to The PCIe cofigration space address specification, we can get the address f8010000. We can read it through Dumphys to change the physical address value: The value read in Figure 3 is 07 04 90 00, which corresponds t
