i am trying to access PCI address space in imx8mmevk board using md command,

the u-boot hangs after typing this command,

i was expecting to see the device id and vendor id as this is PCI base address

 

u-boot # md  0x33800000

is it not possible to see the PCI address space using read command from u-boot.

I checked the uboot source code, it seems uboot doesn't enable pcie, you can use memtool in the kernel when board boot up to read the register

the uboot patch you gave me seems to be incompatible with my BSP 

i.MX Linux Yocto Project BSP 6.1.22_2.0.0 Release
