Although I recommend the use of libgpiod, for direct hardware access you may find the RP1 support in pinctrl (https://github.com/raspberrypi/utils) useful as a starting point.

I don't think enabling PCie at runtime is supported. I wouldn't be surprised (can't check right now) if the firmware has to turn on some clocks etc.

There's a ticket open with Synaptics for this issue. I'll report back with any questions or findings.

Can you do what @porst17 did and add `brcmfmac.debug=0x100000` to `/boot/cmdline.txt` (keeping it all in one line) and reboot? Any firmware crash should then generate a log like the one...

Thanks for that, @WLBQE. I've passed it on.

I've received two test firmwares from Synaptics, numbered 1 and 2. There was no accompanying information, so I don't know if they might be a fixes or whether they are...

@Smyl3 I understand - enjoy the lack of crashes. @porst17 Thank you - that's sounding promising.

Thanks - I'll feed back your findings. Did you try `test1`? Did anybody else try the new firmwares?

Thanks again. Until we are able to reproduce the issue we are relying on people like you.
