Hi,

i saw this guy adding fans to his cluster board setup.

Since there seem to be 12V pins at J1 (http://files.pine64.org/doc/clusterboard...ematic.pdf) can i just add a PWM and a 12V fan?

Is there a FAQ where these questions are answered?  If so I apologize as I haven't found it.

1. Will you be shipping the Pinebook Pro to Norway or Norwegian distributors?
   
2. Will there be a Nordic variant of the keyboard?
   
3. Can I boot from SSD if I install it using the PCIe x4 to m.2 NVMe-adapter?
   
   

Note: tests (1) to (5) with CPU Fan control set at 127 with open NAS case. SATA card from Pine64.

(1) Creating a 40GB file on SATA drive

WR Red 4TB

WD Black 4TB

HGST He 10TB

[email protected]:~# dd if=/dev/zero of=/mnt/hd1/40gb.txt bs=4096 count=10485760
10485760+0 records in

So the WR Red 4TB is not too surprisingly the slowest, it's also the cheapest and consumes much less power and runs quite "cold" compared to the others (for this last thing, I did not measure it, I just touch the disk). It's 5400rpm vs 7200rpm anyway. Otherwise the HGST basically leaves the WD black in the dust.

(2) Both at the same time (hd1 = WD Black on SATA port 3, hd2 = HGST on SATA port 4)

[email protected]:~# dd if=/dev/zero of=/mnt/hd1/40gb.txt bs=4096 count=10485760
10485760+0 records in
10485760+0 records out
42949672960 bytes (43 GB, 40 GiB) copied, 208.836 s, 206 MB/s

[email protected]:~# dd if=/dev/zero of=/mnt/hd2/40gb.txt bs=4096 count=10485760
10485760+0 records in
10485760+0 records out
42949672960 bytes (43 GB, 40 GiB) copied, 255.631 s, 168 MB/s

So, if you write on both drives at the same time port 2 comes... well, second.

(3) Copying each file other one after one (hd1 = HGST on SATA port 3, hd2 = WD Black on SATA port 4)

[email protected]:~# time cp /mnt/hd1/40gb.txt /mnt/hd2/40gb-1.txt

real    3m56.745s
user    0m0.368s
sys    2m49.948s

[email protected]:/var/log# time cp /mnt/hd2/40gb.txt /mnt/hd1/40gb-1.txt

real    3m40.534s
user    0m0.392s
sys    2m45.976s

(4) NAS case (still open), testing power consumption (n.nnA) and temperature (nnC), no disks attached:

- Average 1.06A when system is idle with CPU Fan control set at 127 (a little bit noisy)
- Average 1.12A when system is idle with CPU Fan control set at 255 (very noisy)

(5) NAS case (still open)

- With one WD Red 4TG plugged-in, writing 40GB file (zeroes): 1.28 to 1.41A
- Burst to 2.2A at boot for less than a second with two WD Red 4TB
- With two WD Red 4TB, writing 40GB file (zeroes) on both: 1.45 to 1.68A, CPU temp max: 45C, Disk a: 30C and 180MB/sec, Disk B: 30C and 171MB/sec
- Same plus stressing CPU (sqrt) on 4 cores: 1.57 to 1.80, CPU temp max: 51C
- Same plus two additional SSD attached via unpowered USB 3 (SSD not connected to SATA): 1.90A to 2.12A, CPU temp max: 55C (I believe the 55C was reached because I did not wait too much after the previous test).

Note: the test below is now with the NAS case closed. CPU Fan control still set at 127. Case Fan 80mm set at 2/3 speed. Room temperature 24C.

- Idle CPU at 34C
- Idle disks at 29C

(6) Writing 40GB file (zeroes) on both disks.
- 1.64A to 1.89A, CPU temp max: 45C, both disks at 30C. Note: the slightly extra load in amps is from the case FAN and the mini-card controller I added.

CONCLUSION: so far, so very good, extra room in power with the 12v 5A PSU.

Other remarks:
- The U.FL MHF4 plugs are a hassle, once you start to put all the pieces into places they have the tendency to disconnect. You basically have to connect them last which a big pain in the neck when you have big fingers.
- I'll test again the temps with the case fan at half and 1/3 the power.
- I'll receive the Marvell 88SE9230 4-port card from Aliexpress in about a month (just to play with 2 HD + 2 SSD). For HyperDuo it will be a challenge because I did not find a software to configure it on Linux yet (but there is a driver) and there is no BIOS so no config via the BIOS either. Still Googling. Anyway, I think this card will end up in a PC.

Hi all,
has someone tried to extend the cable of the 13MP camera?
I just need 5 cm more but in the current configuration I cannot find any way to make it work.
Could you advice a cable and a female-female adapter? Would it work?
Thanks

I just got a Rock64Pro and I installed DietPi (running MATE as the UI) on it.  Boots up just fine, but the video is standard HD (1920x1080).  I went into Control Centre and 4K resolution isn't even listed in the Resolution drop down.  Anyone have any suggestions on how I can get/enable 4K resolution?  

The monitor is 4K, and Rock64 running DietPi operates in 4K mode.  I'm using the Rock64Pro version of DietPi.

Thanks,

Richard

Here's an update.  I was able to find an article online which provided me with the following commands to switch to 4K mode:

    xrandr --newmode "3840x2160" 338.75 3840 4080 4488 5136 2160 2163 2168 2200 -hsync +vsync
    xrandr --addmode HDMI-1 "3840x2160"
    xrandr --output HDMI-1 --mode "3840x2160"

When executed in Terminal, the system will switch to 4K resolution.  And under Armbian Ubuntu, if I add those lines to ~/.profile, Ubuntu boots to 4K resolution.  When I tried adding those lines to ~/.profile under DietPi (with MATE as the UI), it doesn't work.  

I'm guessing that with DietPi/MATE, I need to add those lines to a different file.  Does anyone know which file I need to edit?

Hi,

Rock64 boards are supplied inside the cool plastic boxes. Where can I buy such boxes?

Hello, 

I need help configuring eDP port, when the LCD is connected it actually powers on, but the secreen is black. Any Idea how to fix it or at least from where should i start ? Thank you

Hello,
It's been a month since the last post in this forum and while i have my project "working" there is a ton of functionality that I thought i could get out of this board assuming an ASOP ROM with root access would be on the way.    Is this planned? I got two boards hoping that the RockPro64 could be the foundation of my projects but, not out of impatience just lack of being sure that this is still active, am thinking about moving to another arm board with more active development.  In any case: just a delay or is this not planned for the immediate future?
Thanks for your response

Hi,
Just got my Rock64Pro and installed Ubuntu 18.04 Bionic    LXDE Desktop aarch64  from SD card

All seemed to go well, but there is no "Top Menu" So i cannot find a way of accessing network settings, for example to setup wifi using a dongle.

previously using Debian on RPI.

Any ideas

Max

Hi Everyone,
I am new to Single Board Computers and Arm Architecture. I have been using GNU/Linux on my X86 as my main desktop Pc for a few years. This is my current configuration of my pc: Distro: Release Linux Mint 17.2 Rafaela 64-bit - Kernel Linux 3.16.0-38-generic x86_64 - Desktop Manager : MATE 1.10.2 - Hardware: Memory: 8:00 Gb - Processor: Intel® Core™2 Quad CPU Q6600 @ 2.40GHz × 4 This pc is connected to the cheap display via HDMI (A 40 in Westinghouse led TV) With these configurations I have everything I need for work, play and fun.
I would appreciated very much if anyone can help me with these ?:-)
What is the differences between the Rock64 vs RockPro64 ?
Is there any option for booting to the system with different OS like Grub loader?
Is the 1 Gb of Ram + add on Dac be good for Volumio?
Thanking in advance an Rock On:-)
Cheers,
Phamo
