M.2 PCIE is it powered on?

I’m having issues with the RK3399 even recognising that there is a PCIE bus let alone getting it to work

It appears from the following that the voltage regulator is not configured to feed the pcie:

[    0.263224] vcc_lcd: no parameters
[    0.263337] reg-fixed-voltage vcc-lcd-regulator: vcc_lcd supplying 0uV

but some of the other bits are configured to provide power. I’ve been looking at the device tree files, but I’m a bit stuck as to what is missing - I don’t really know what the gpio parameters are, and the only thing I can think of doing is setting it to be always on by setting it’s voltage parameter to 3300000 in the dts like it is for vcc3v3_sys

any ideas?

Same issue here. Two Firefly RK3399’s, brand new, ordered and received about a month apart. Wondering about some physical board mis-configuration/installation or removal of 0-Ohm options/etc. Here is a dmesg | grep pci output:

Hi everybody,

did you manage to get the PCIe on the NGFF working?
I myself also have an RF3399 with the intent to use it as a storage server by using this PCIe 2.0 to 4x SATA adapter
https://www.delock.com/produkte/G_62850/merkmale.html
Unfortunately it didn’t work right from the start (same messages as you see). So there is obviously stuff to do with the device tree but after measuring the PCIE_3V3 signal I found that the supply voltage from U15 is there.
The main issue seems so be differrent:
M.2 has 4 config pins
config_0 : Pin 21
config_1 : Pin 69
config_2 : Pin 75
config_3 : Pin 1
as described here http://pinoutguide.com/HD/M.2_NGFF_connector_pinout.shtml
If you look at the schematic you can get the impression that config_0 is not connected and the others are connected to GND (with the caveat that the Pin numbers in the schematic does not match the official pin numbers, e.g. config_0 is numbered 13 instead of 21).
This would mean the board will only be able to accept WWAN-SIC (if config_0 is left open) or SATA (if config_0 is tied to GND on the m.2 card).

http://www.computex.biz/PhotoPool2/201406/201406251407499629.pdf

Unfortunately for me my PCIe > SATA adapter pulls config_1 to PCIE_3V3 (which leads to high current consumption and is also not correct).

So I have some questions to the Firefly Team:

  • Can you provide a schematic with correct config pin numbers
  • Why did you connect all this config pins to GND instead of pull them up to PCIE_3V3 and route them to GPIO as proposed here https://mindchasers.com/dev/m2-connectors ?
  • Is config_1 (pin69) actually connected to GND (without a 0 Ohm bridge)
    • If so, can you provide a board layout with this line highlighted so I can (hopefully) scratch it off?

Best regards,
Mathias

FWIW, had the same -110 error with M.2 SATA card (ASM106x chipset) on NanoPC-T4 (RK3399) with 4.4.x from FriendlyARM and from Rockchip, but problem went away on mainline 5.8.5. Details here: https://discuss.96boards.org/t/pcie-link-failure-with-pcie-device-card/9643/7?u=redfish
