Jetson Nano doesn't show up Mini PCIe device when checked with lspci -v

Mar 04, 2024

Hello,


I am having a module called MT7915AN(Mediatek) which is wifi module connected to Jetson Nano board with M.2 key E using M.2 key to Mini PCIe adapter. When I checked it with the lspci -v command it doesn’t show up the device is connected. I have attached the dmesg log there it shows pcie - 0 link is down, retrying and end up with ignoring. Also attached pci log (dmesg | grep pcie). I am using barrel jack power supply of 5V 4A. The module MT7915AN requires 3.3V voltage and 3.5A current.

1.Is Jetson nano carrier board is able to provide this much of current when USB keyboard, mouse and hdmi are attached?

2.Do I need to modify dts and dtsi to add node/subnode?


Thank you in advance.
