Hi, I’m trying to use the Nano DevKit with PCIe switch. According to other posts, I saw that I need to add the following entry in the PCIe nodes pci@1,0 & pci@2,0 nvidia,disable-clock-request; (basically, where ever you find ‘nvidia,num-lanes’ entry, add the above one in the same node) This sh…

It is valid for all DevKit versions Look for the file “tegra210-porg-pcie.dtsi” and make modifications in this. Yes. It is valid for the production module as well BTW, this solution is about dealing with PCIe devices that don’t pull the CLKREQ# signal low but expect the REFCLK to be available.
