Hi,

I found Android P SDK on Wiki.
Who was already downloaded and build it?

https://wiki.pine64.org/index.php/ROCKPr...ndroid_SDK

If someone tried it, i want to know how to build and burn to sd card.

Hello

I would like to connect a fan to the rockpro64 board, but I don't know the exact type of the board connector. Does anybody know which connector is compatible?

Hi, this is my first time to post my small project here with clusterboard.
I try to build a small weather HPC in my home, which can collect data and run weather model to forecast the next 48hr forecast.
Hope you like it~

Greetings all,
I am a new user of a Pinebook 11.6" 1080P. I am experiencing an issue where the wifi interface stops working after some amount time - about one hour. After that, it shows no networks available and persists in that state until the system is rebooted. I am running wpa_supplicant from systemd with the default options; Network Manager is disabled. Currently I am running Armbian_5.86_Pinebook-a64_Ubuntu_bionic_next_4.19.38_desktop -  but I think I also experienced this issue with Armbian_5.86_Pinebook-a64_Debian_stretch_next_4.19.38 and maybe even with the stock KDE system. Has anyone dealt with an issue like this? Is there a kernel module I could try reloading or some way to reset the network interface so I don't have to reboot the computer to get back online?
Thanks!
Charles

I am trying to connect either to the wifi router outside my vintage metal skinned camper or a Windows 10 desktop with a ethernet connection for internet and a wifi usb adapter on it running the mobile hotspot.   I am having authentication failure with this encryption. Anyone else have this or a solution?  I tried adding to the wpa_supplicant as found on a guide i googled and nothing. any help? the wifi usb is good, it just is not authenticating in this encryption....

Hi,

I'm looking at purchasing a Pine H64 and using Armbian for a project that mostly requires network (around 128kb/s up and 128kb/s down) and storage (90% append-only write).  However, I'm concerned about the following at https://www.armbian.com/pine-h64/ :

--- CUT ---
- USB3 sometimes doesn’t detect high-speed devices properly
- random MAC
- limited 3rd party hardware support
--- CUT ---

For the network, I'd like to use the integrated wifi, but need a fixed MAC (for port-forwarding).

For storage, I'm looking at using a Toshiba HDTB410XK3AA Canvio Basics 1TB connected directly via USB3.  Does anyone know if this might be an issue (e.g. power and/or compatibility-wise)?

I still haven't decided about SD/eMMC for boot/root (but would like to use u-boot).

Does anyone know if the issues mentioned above have been resolved?

Regards,
sysop

Does anyone have the size limit of the upcoming pinebook tablet? I hate that my current android won't see over 32GB

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

root@rkpro64:~# dd if=/dev/zero of=/mnt/hd1/40gb.txt bs=4096 count=10485760

10485760+0 records out

HGST He 10TB

root@rkpro64:~# dd if=/dev/zero of=/mnt/hd1/40gb.txt bs=4096 count=10485760
10485760+0 records in
10485760+0 records out

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)

root@rkpro64:~# 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

root@rkpro64:~# 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)

root@rkpro64:~# time cp /mnt/hd1/40gb.txt /mnt/hd2/40gb-1.txt

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

root@rkpro64:/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.
