Linux/AM5728: PCIe link establishment problems

Part Number: AM5728

Tool/software: Linux

Hi All,

I am using AM7528 GP EVM with Linux_SDK_03_02.

With this, the link doesn't come up during kernel boot:

[ 0.603117] PCI host bridge /ocp/axi@0/pcie_rc@51000000 ranges:
[ 0.603128] No bus range found for /ocp/axi@0/pcie_rc@51000000, using [bus 00-ff]
[ 0.603160] IO 0x20003000..0x20012fff -> 0x00000000
[ 0.603180] MEM 0x20013000..0x2fffffff -> 0x20013000

[ 0.816328] dra7-pcie 51000000.pcie_rc: link is not up

Can anyone tell me why it is showing 'No bus range found ' and 'link is not up'?

Thanks & Regards

Srikanta
