FA SOM-RK3399V2


Recommended Posts

Is there any way/plans to support the FrindlyArm RK3399 SOM in Armbian? Does anyone know the hardware well enough to know if another firmware could be loaded on it? It seems to be a very nice module, and the dev board has just about everything one might want on it.

 

On a side note, possibly derailing my own topic, is there any plans to add any of the VPU patches for the RK3399 and associated software? It seems like support for that is getting pretty close, and it would be great if some of the patches that are floating around could get include in the official distro. I'm about to dive in an try getting at least accelerated ffmpeg working on my M4V2 and/or neo4, but have been hoping that it would get into the standard distro first. :-)

Armbian is a community driven open source project. Do you like to contribute your code?

Well, what do you know, it works!

 

At the very least, ethernet, wifi, and hdmi work. I don't know what else to test on it ATM. I plan to try an NVME drive, but that's still in the mail, and I'm curious if USB-C display will work.

 

One thing that interested me about this board/module was it's advertised ability to work with just a USB-C cable. It could be a really interesting board in that respect.

This is great news. If you can simply try further features of the board and report if they work or not with the m4v2 image. If somebody finds time initial support for this board can be added by simply copy paste.

It appears that the USB ports are not working. Is there something in the device tree that enables them, or enables the power for them? It doesn't seem like anything happens when I insert a card, but I don't see anything in the schematic that would control power to them, other than the over current protection chip.

This may also be "human error", but the USB-C is not working, at least not the same as with the FA image. With the FA image, I can plug a USB C "hub" with HDMI, ethernet, USB, etc, and it powers up during boot and works as expected, which is very nice. With the armbian image it does power up at all.

 

I believe the M4V2 only uses USB C for power, so I don't think think it has an equivalent of this, and I don't know where to look for how to enable it. Might there be a kernel configuration? The schematic shows a vbus detection line, power control, and some sort of interface IC (FUSB302MPX).

Is it with legacy or current/dev?

Legacy should probably work as it is based on FA kernel code directly and DTS differences between the two boards are minimal.

With current/dev it might be a whole different story though...

Maybe @piter75 finds time to add this board as CSC

I can do that in the "mean time" ;-)

Are there any RK3399 boards where USB-C works with Armbian mainline?

AFAIK it is non functional yet...

 

Did you test your RK3399V2 SOM for stability in mainline?

M4V2 has some known stability issues that I currently attribute (maybe wrongly) to memory / design used.

RK3399V2 SOM uses the same RAM chips and I wonder if it shares the same issues.

Is there s stress test that I could run?

For me it usually takes no more than few hours of memtester (apt install memtester) running to see first failures with M4V2 in mainline.

 

You can run it this way as root (for 4GB board). For 2GB the value of memory reservation for testing should be lower.

memtester 3280M 2>&1 | tee memtester.log
