I’m trying to debug my system. Along the development process (involving DT modifications), the onboard ethernet support disappeared. I didn’t notice it immediatly, because I couldn’t test it for a while, so I didn’t check for regression.
It appears that the whole PCI support in the system got broken at some point. There’s no ethernet support (also the leds are not active anymore), and the lspci outputs nothing.
I could flash a much older version of our system, with the PCI and Ethernet working, and lspci gives me correct output:
root@jetson-nano-emmc:~# lspci 00:02.0 PCI bridge: NVIDIA Corporation Device 0faf (rev a1) 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 19)
I have extracted the two DTS… The one on the working system, and the one on the faulty system… But I can’t figure where it went wrong…
I’m uploading bith dts files for comparison…
