PCIe

[Der Geist der Maschine]

The Pinebook Pro supports PCIe, doesn't it. Lspci shows nothing. I would have expected a root-port or so.

Dmesg:

Are above errors expected? Do you also get them?

It's possible that the Pinebook Pro NVME uses a custom PCIe driver for RockChip CPUs.

A better comparison would be to check the ROCKPro64 which uses the same CPU chip, and has more general purpose PCIe slot. They support SATA cards in addition to a PCIe to NVME card.

But, I would think "lspci" should show something valid.

Same problem here. Nothing in lspci and lsblk. Tried to do it in the default Debian and the newer Ubuntu. Modprobe shows that nvme module is loaded. I thought I somehow damaged the cable or something else during the installation, but, since there is another person having the same issue, I would want to know if it's software to blame.
