Rock PI 4

Recommended Posts

Hi all,

 

a new RK3399 board appeared, it is called RockPi4

 

I have two of these beasts here already, and they works nicely - I like the small details about it (nice eMMC fixture, all heat plates on the bottom side for simple cooling, and an M.2 PICe slot for my second network card :)

Do you see any chance to get Armbian working on that beast, and if so, what can *I* do (with my limited experience in kernel programming)?

Debian is working on it already, in case you need more specific information please let me know.

 

Any help is appreciated.

 

So far, Michael

@mboehmer It's a sexy board. Looks like the perfect RPi 4B. But I bet the real RPi 4B want be this powerful and cool.
I also hope Armbian can support this board, I think it will depend on how many are sold, and how many people ask for it. So good thing you've asked for it.

I hope to get a RockPi4 too to review. Good luck with it.

Hi Igor,

 

yes... I know. I have patches prepared for Uboot 2018/Odroid C2, Tony takes already a look on.

I'm not a kernel programmer, but willing to test - needing a starting point, i.e. someone to include the RockPi4 into the Armbian development tool.

So, instead of pointing me to the general "contribute" page, what would be the best "first step" for me?

 

Michael

Project needs various help. Dealing with "boring"  bash scripting perhaps? Writing docs, maintaining some board, ... there is plenty of things. Read that page again.

Hi Igor,

 

I'm a VHDL programmer mostly, with C on microcontrollers. Bash is out of my reach - too complicated...

Honestly, if I can contribute by different means, I will do (and will read that page again, as suggested).

Are you sure that there is really no FPGA to be programmed? :)

 

So far, Michael

:lol: Armbian on Zinq !

Zinq = Xilinx = NoGo.

I started with Xilinx FPGAs, but use only Lattice ones nowadays. There are company policies which I don't support at all.

Maybe a Mico32?

So, to get back to facts, build is running, may take a while.

Just compared the RockPI4 with the NanoPC-T4. Seems a good choice for starting, bioth RK808D and RT8211E are the same.

Audio circuit is different, the RockPI uses an ES8316 instead of ALC5651.

Wifi/BT is at least similar, on the RockPI there is an AP6256, compared to the AP6356 on the T4.

IR is missing.

 

Update: NanoPC T4 image compilation succeeded, but fails booting. It starts the BL31, but hangs after two NOTICE lines.

BL31 version of original image is different to the one used in NanoPC T4 image.

I can post both boot logs, if anyone is interested (good ol' FT232AM works with 1.5MBaud, while Prolific fails :) )

It is maybe the same issue I'm facing for RockPro64 where I'm not able yet to have a working U-Boot ...

In the mean time, as a temporarily workaround, I'm overwriting the u-boot sectors of freshly built image with the ayufan one.

LPDDR4
64bit dual channel LPDDR4@3200Mb/s, 1GB/2GB/4GB optioal

 

as far as I know, all boards which work with upstream u-boot are DDR not LPDDR based...

At least they implement PD properly.. Hopefully they deliver a proper heat-sink for it.

 

Did you ever diff'd ayufans u-boot against upstream? :lol:

RockPi4 sales start officially today. I got two preproduction run boards, one was clearly not yet optimized in soldering :)

Accoridng to revision printing on silk screen it's the final version being sold.

One issue only so far: the M.2 adaptor is from a different board, but works electrically.

Could you share the link to purchase?

I'll have to get my house in order (Mess-on 64) and Rocktastrophe), this board does look interesting, although that M.2 seems awkward, and the typical "both sides must be smart" statement for the USB-C PD.  There will be a lot of low-information users having problems with this board.
