Oh, yup. That's my issue! Thank you. Where did you find that little snippet of documentation?its only valid after you bring the pcie controller onlineThis would suggest to me that the memory address is not valid in a bare metal environment...Does something need to be configured to create that mapping?that option will leave it configured, so you can skip a stepBy default, the PCIe X4 interface is reset before loading the kernel so that the PCIe RC is in a clean state. For bare metal / bringup you can add pciex4_reset=0 to config.txt because writing a bare metal PCIe RC driver probably isn't everyone's cup of tea
