Hello,

Please validate your RCW configuration ( According to the SERDES configuration you selected), you can also try to test the pcie device under u-boot to se if the device is recognized with the pci commands.

Your Linux complains that it cannot assign the amount of memory the peripheral connected to the PCIe wants, please share complete log file in .txt format.
