Will have to build a new Dev kernel and see if my M2 drive is recognised.I've built the current branch which is 5.4.20. You could go dev which I believe is 5.5.x.

I've build 20.02. It's working fine (still powering via 12V).
Which version kernel does that use?

Would be neat if the SBC could appear as a USB ethernet gadget. you can connect a raspberry pi 4 to an iPad pro via USB C like this. Would be good to do in Armbian as well.Plan to clean up this a bit later, but I thought for now I'd lay the topic down for the forum to address.
Topic:
USB 3.1 Type-C (thunderbolt 3) as a multi port usb HUB
Regards: (newer phones, laptops, sbc, routers etc?)
Armbian / u-boot capable devices that currently can be powered by a type-c 3.1
Reason: ? Any thoughts on what someone would like to do with one of these? Reply with thoughts please!
My thoughts: Armbian / and or Openwrt + the 8in1 adapters = OTG FTW
Use Armbian core or friendlylywrt to plug n play managed "smart" scripts.
Diy, router / switch managed
or one script make an unmanaged transparent bridge with / tap
o /SPAN / aka mirror port....
Holy shit its a freakin HUB!
I think its a basically a raspberry pi zero sized board with the chip/mod for passive networking via type-c host controller.
With some freaking amazing chips. Heres the standard chips I found on my 8in1

Heres the one I bought, but I almost bet the inside are exactly the same.. for the 8in1s ( you can find much better prices than this. mine was $20 for some daily deal)

They have been really quiet, they still have 2 or 3 boards they were going to launch last year that never launched on Indiegogo or Kickstarter. Maybe because of problems/negative feedback from the renegade elite, and long delays on la frite as well?
If only firefly/loverpi/libre were of any help. I'll post it on their forum and hope for the best.

Mine booted with 5.5rc2 but had a crash when starting openSSH with 5.5rc3, and rc4+, not sure if it's because I didn't make clean. make dtbs-install copies the dtb files to /boot/dtbs/(kernel version/rockchipIf you're building 5.4.y, try tag:v5.4.6 instead. I couldn't get latest master to boot properly on this board.
My installed uboot seems to expect the dtb to be /boot/dtb/rockchip. Now it won't power on at all, I assume it's because I pulled the power lead out at the wrong time so I'm building a new image file to flash onto the SDcard.
I haven't used make dtbs-install before so don't know if that's new behaviour or not.

Nice, will give it a goNo, just classic kernel make, native on the board.

I think you have to add one to your cart and start the checkout process to calculate shipping

The libre.computer website purchase page has links to LoveRPI.com and Amazon USA, which website are you looking at?Maybe I was looking bad, but I did not find the information, how much is the delivery of this model in Russia, if you order on the official website of Libre Computer ?

Great, thanks for the info. Will try 5.5 when it's released.The M.2 M-Key (PCIe) slot on the mezzanine board is supported from mainline kernel 5.5-rc1 on and works with NVME SSDs.

Yes it's a neat board with the Poe mezzanine M2 SSD and single Poe cable.
I confirm that booting in POE circumvents the USB-C issues I had... My final spot for this thing will be in a cabinet powered by POE as well

I'm booting with it powered by Poe though, it has another converter on the mezzanine I think. Which then feeds the board?
As stated, the 12V rail (feeds the mezzanine) is run by a buck/boost converter with no mainline driver, so it sits at 5V instead of 12. (4.67 volts, in my case). The board would always boot with a large enough "dumb" supply, but a USB- power delivery supply would default to ~400 mA and fail.
No idea how it is wired so that quite probably goes to buck boost converter on board as well.
The Poe switch says it's drawing about 70mA at 50+ volts DC, the switch can power at 24v or 48v.

I have it running with the poe mezzanine, with an Armbian image built with the docker ubuntu method and it seems to be running okay. When I did an apt-get upgrade it downgraded the kernel to 5.3, so I rebuilt a current 5.4 kernel image with the docker ubuntu method and with both kernels there is no pci express as the m.2. ssd is not being recognised.
I tried again with custom kernel config but Rockchip pcie is already being compiled but I can't find any kernel messages about pci express.
The only difference is with the 5.3 kernel and 5.4 kernel I can see is a green led comes on the mezzanine when 5.4 is running.
Is the mezzanine pci express?
