  Network problems (actually bad power supply)
Posted by: Unkn0wn - 08-26-2019, 03:00 PM - Forum: Clusterboard - Replies (14)

But different from the problems I've read so far.

Using the latest version of Armbian Buster all the modules boot and are accessible. However after a couple of hours the modules become unreachable one by one. After ~1 week only 2 of the 7 modules are resolve-able over the network. All modules have a static IP natively, however I have tried with DHCP and a static IP on the gateway. Here a network ping to a "off-line" module:


Code:
C:\WINDOWS\system32>ping 10.10.10.70

Pinging 10.10.10.70 with 32 bytes of data:
Reply from 169.254.1.1: Destination host unreachable.
Reply from 169.254.1.1: Destination host unreachable.
Reply from 169.254.1.1: Destination host unreachable.
Reply from 169.254.1.1: Destination host unreachable.

Ping statistics for 10.10.10.70:
   Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

C:\WINDOWS\system32>

I do not know whether the system is actually running. What kind of serial interface should I be using to debug this?
The extra software I am running on the modules is docker (18.06.3~ce~3-0~debian), containerd.io (latest) and kubernetes (1.15.2).


p.s.
the software date on some of the modules jumps randomly to october 2119 on the command date, but the hardware clock shows the correct time (hwclock). This is resolved after a reboot and is unkown whether this has something to do with the network, I just thought it was important enough to mention.

EDIT: After having physical access I think I've found the issue. I believe it is twofold:
1. Misconfigured switch and gateway. Couldn't prove this one, but I believe it caused a part of the issues I had.
2. Faulty PSU. I use the 5v 15A PSU from the Pine64 store, and on top of making poor contact between the AC cord and the adapter, it is faulty and not able to sustain all modules under a full load. I've asked for a replacement unit.

EDIT2: Ordered a ATX PSU, will see if that goes better.

EDIT3: With an ATX power supply the modules are working perfectly, even under heavy load and for sustained amounts of time. However I still have the time drifting issues.


  RockPro 64 V2.1 Boot problem only DDR Version ... message
Posted by: nutilius - 08-26-2019, 09:36 AM - Forum: General Discussion on ROCKPRO64 - Replies (5)

Hi !

I have problem with starting any opsys from SD card.

When I try to boot, after switch the poer I see only message:

DDR Version 1.19 20190305
In

and nothing more

Previously I used different OSes (Armbian and NetBSD), but now I couldn't even go to u-boot (without sd-card I got nothing).
Any suggestions ?

My board is RockPro64 V2.1 2018-07-02

Exclamation Expired coupons + similar issues
Posted by: Luke - 08-26-2019, 09:18 AM - Forum: General Discussion on Pinebook Pro - No Replies

If your Pinebook Pro coupon expired by accident, or you encountered some other pre-order issue, please email pinebook@pine64.org NOW. You have until Friday this week to sort it out. Requests to reissue coupons after Friday August 30 won't be honored.


  Public preorders are now open!
Posted by: fire219 - 08-25-2019, 10:43 AM - Forum: General Discussion on Pinebook Pro - Replies (9)

As of noon (12:00) UTC August 25th, the forum preorder phase has ended. A total of 884 users went through that system for the one month it was in operation.

It is now possible for everyone (even non-forum users) to preorder a Pinebook Pro. To do so, simply complete the order through the Pine64 store at this page. Do not order using the "Community Edition" item on the store. That is the 128GB option used for the forum preorder system, for those who have not yet had the chance to complete their order.


  What time will PBP orders be opened up to the public?
Posted by: msquared - 08-25-2019, 07:55 AM - Forum: General Discussion on Pinebook Pro - Replies (7)

I assumed that orders would be open to the public at midday UTC (same time that community-only orders were opened up on July 25th).  Am I wrong?  I ask because I can't seem to order a PBP yet.


  PBP benchmarks
Posted by: CJMax - 08-25-2019, 03:27 AM - Forum: General Discussion on Pinebook Pro - Replies (27)

Would it be possible to get some benchmark results of the Pinebook Pro? I found a RK3399 results on geekbench, I suppose the Pinebook Pro will have comparable results? 

These are the results I found:
https://browser.geekbench.com/v4/cpu/sea...3&q=RK3399

I'd love to play around with the PBP but I'm just not sure it would be powerful enough for my daily office work (quite some browser tabs, libre office sometimes with large files, remote desktop via x2go and vnc, VPN...), so any benchmark numbers would be greatly appreciated. I've seen the youtube videos showing 4k video playback and 3D, but those are not really the things I'm after.


Photo UMPC Version Idea: PINEPALM PRO
Posted by: Secular_Squirrel - 08-25-2019, 01:20 AM - Forum: General Discussion on Pinebook Pro - Replies (27)

[Image: hsdBAVY.jpg]


First of all, this product doesn't actually exist.......... however if there is demand for it it may just be able to become real!

I am making this post to ask the question of "Would you buy it?", however since not everyone is a fan of UMPC units, I must ask the additional question of "Do you like pocketable UMPCs with a clamshell form factor and keyboard?"

This image is a mock-up intended to convey what is intended to be represented, voltage listed is likely off, mock up was done in a hurry and without much homework being done so please keep that in mind!


Currently there are several products on the market that resemble this device, some have yet to be released, also there have been quite a few more in the past. The list below is mixed and totally not in any order. The Gemini PDA and Cosmo Communicator stick out for having a low profile mechanical keyboard, some of the items on this list are a little dated. I owned an Openpandora at one time, but it broke on me and I was never able top get it repaired, I used it mainly for mobile word-processing and it did the job very well and at one time or another have looked into getting the other units on this list for that same purpose. If you go through this list and check what these badboys are selling for (Some of them you can't even find being sold used anymore), you'd find that this theoretical "PINEPALM" unit selling for the same $199 price tag as the 14" Pinebook Pro Linux Laptop would actually allow it to compete with the below items as a budget option for a full qwerty clamshell all in one UMPC.

GPD Pocket 2
Dragonbox Pyra
GPD Micro PC
Viliv N5
Gemini PDA
Cosmo Communicator
UMID Mbook
Fujitsu Lifebook U1010

  Rockchip RK3399 PCIe lanes only 2.5GTb/s?
Posted by: Arwen - 08-24-2019, 05:02 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (2)

Okay, I may be wrong, (it's rare, but happens :-). From my reading, it appears that the PCIe lane speed is 2.5GTb/s, (aka PCIe 1.x speed), verses 5GTb/s in 2.x. (That said, the chip seems to support the protocol updates in PCIe 2.1.)

So, anyone else read it that way?

Here is a reference;

http://opensource.rock-chips.com/images/...170420.pdf
Page 89

Quote:Signal data channel data rate maximum up to 2.5GTb/s, with 8b/10b form, the maximum data rate up to 250MB/s

Next line adds the following, (which implies all 4 lanes working together);
Quote:Work in full-duplex mode, maximum data rate up to 10GTb/s, which is 1GB/s

All that means, (if I've read that right), is any NVME drive will be limited by this change. Probably not an issue for 4 lane NVME drives. Though 2 lane NVME drives, (like that nice low power Western Digital Blue), might suffer a little. This will not stop me from using a NVME drive, though I might make more effort to find a 4 lane device that has reasonable power usage.

Also, (my original reason for the research), it appears that the 4 x PCIe lanes can not be bi-furcated into 2 x 2 PCIe lanes. All 4 must work together, as either 1/2/4 lanes. (So it DOES support 2 lane PCIe devices, like the afore mentions WD Blue NVME drive.)


  Expired coupon code :-(
Posted by: frank-zappa - 08-24-2019, 04:50 PM - Forum: General Discussion on Pinebook Pro - Replies (3)

I was away from my email when the coupon code arrived.
By the time I got round to entering the code it had expired. I tried to apply for another code at https://pine64.org/PBPCoupon/index.html and was told 


"Login was successful.

Sorry, you have already entered the preorder queue."


Is there any way I can get a new code? 


  12V 3A power supply and NVMe - PCIe
Posted by: kaylios - 08-24-2019, 01:45 PM - Forum: RockPro64 Hardware and Accessories - Replies (3)

Is the 12V 3A power supply enough if I use the PCI-e X4 to M.2/NGFF NVMe SSD interfce card ?
Even if I add things like USB keyboard, USB to ethernet and hdmi screen ?
Or should I buy the 5A one ?

thank you guy
