Question

This really takes the cake since it has the SoC on the bottom where you can't even put a heatsink.

 

Same with your ROC-RK3399-PC (Renegade Elite): https://libre.computer/products/boards/roc-rk3399-pc/

 

How do you plan to solve heat dissipation there? And do I get it right that the USB-C in the upper left corner is meant as a generic 12V input?

@piter75 Are you planning to send the ATF "switch power domains on before reset" patch upstream to https://review.trustedfirmware.org/ ? It fixes the issue with mainline ATF + Linux where Linux will hang after rebooting; I have tested the patch with my own custom build of Debian and it now reboots 100% successfully. It would be really useful for all mainline distros if it was applied to mainline ATF.

Sorry for offtop, but I have some question about this SBC and Mezzanine extention before ordering:

 

1) Can I use power port on Mezzanine extention for powering main board?

2) USB WiFi is working, or I need to dance around with drivers/kernels etc?

3) Any body use 2 cams?

 

And finaly. I can't understand - Armbian allready released for this board, or not?

 

Thx!

Most of important ones are supported out of the box with best driver found, recommended ones you can find on download pages. If you get exotics, you will have to dance. With Armbian SDK, this is easy.

Mezzanine is powered by the mainboard's USB-C through its connection on the board's GPIO. Otherwise, the mezzanine does offer an m.2 key slot for a wifi module. Sadly, Libre/loverpi is jerking around backers of the board and not delivering missing parts like the wifi module and emmc, so I wouldn't rely on them for these parts.

I build yesterday for this board, and tried it today with no luck.
I have the standard PSU that was delivered with it.
I can boot Android on a SDCard, and Firefly's Linux on eMMC, but not Armbian for the time being.
I haven't plugged UART yet, so I don't know what's going on.

Does this bring some light to power supply?

I'm not sure I got what you meant.
I know there are some troubles with the power units for this board, but as I use the power adapter that was supplied with my board, I thought I would be good to go.
My board can boot Android on the SDCard and Linux on the eMMC with this power adapter.
Would you mean that Armbian would take too much current when starting, so that the board shuts off by itself?

Well... the troubles are not with the power units per se but with the combination of issues in mainline kernel for this board:

  • lack of support for MP8859 buck-boost converter which means it always provides 5V instead of switching to 12V
  • possible misconfiguration of FUSB302B PD chip driver used in roc-rk3399-pc

If I understand the patch correctly, Markus made some modifications to the power curve of fusb302 PD chip to switch usb-c voltage to 15V when more power is needed.

This should workaround power issues when powering from usb-c with pd compliant power units.

Interesting. I don't recall it being picky with the power supply when I tried the images from Firefly.

There is special driver work done in their kernel to cover an unsupported I2C buck/boost converter that provides the 12V rail on this board, and for reasons I'm digging into, the fusb302 driver is a complete mess after they moved it out of staging, it has a lot of odd behaviors and a completely new set of requirements for the device tree.  I temporarily ran it back to the staging driver for our mainline expert builds (limited improvement), but am working on the proper driver.

So far what I'm seeing is dt slop (on all boards using this chip)

1) lack of a connector node, which, when added, brings along

  • lack of port nodes for the connector
  • IRQ errors (related how?  no idea)

2) lack of "op-sink-milliwatt" property

 

Once op-sink-milliwatt is added it will boot, which leads me to believe the chip is receiving commands from the driver, however probe fails with "failed to register tcpm error -22"  I haven't gotten past that, so 5V only, no mode switching.  And I am not immediately inclined to write a driver for the dc-dc converter.  ;-)

 

My current device tree entry:

&i2c7 {
	i2c-scl-rising-time-ns = <600>;
	i2c-scl-falling-time-ns = <20>;
	status = "okay";

	fusb0: usb-typec@22 {
		compatible = "fcs,fusb302";
		reg = <0x22>;
		interrupt-parent = <&gpio1>;
		interrupts = <2 IRQ_TYPE_LEVEL_LOW>;
		pinctrl-names = "default";
		pinctrl-0 = <&fusb0_int>;
		vbus-supply = <&vcc_vbus_typec0>;

		usbc_con2: connector {
			compatible = "usb-c-connector";
			label = "USB-C-0";
			power-role = "dual";
			sink-pdos = <PDO_FIXED(5000, 3000, PDO_FIXED_USB_COMM)
					PDO_VAR(5000, 15000, 3000)
					PDO_PPS_APDO(5000, 15000, 3000)>;
				
			op-sink-microwatt = <25000000>;
			ports {
				#address-cells = <1>;
				#size-cells = <0>;

				port@0 {
					reg = <0>;
					usb_con_hs0: endpoint {
						remote-endpoint = <&u2phy0_otg>;
					};
				};
				port@1 {
					reg = <1>;
					usb_con_ss0: endpoint {
						remote-endpoint = <&tcphy0_usb3>;
					};
				};
				port@2 {
					reg = <2>;
					usb_con_sbu0: endpoint {
					remote-endpoint = <&tcphy0_dp>;
					};
				};
			}; 
		};
	};
};

 

[edit]  I want to be clear all the port definitions could be nonsense, the documentation is a bit thin on all sides of this.  One thing I'd like to consider is the interrupt type, even though the fusb302 specified it's interrupt pin is active low...

 

@Neil Armstrong, in case you have some insight into this.

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?

Yes, it's PCI-E and it is working on the firefly images.

 

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.

I'm booting with it powered by Poe though, it has another converter on the mezzanine I think. Which then feeds the board?

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 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

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.

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 ?
 
The libre.computer website purchase page has links to LoveRPI.com and Amazon USA, which website are you looking at?
