I got my EDGE this weekend. And in the coming days plans to start assembling and testing Armbian for Khadas EDGE.
 
By the way, according to Robert, this model plays well videos up to 4K on Ubuntu from Youtube.

Good news. I'm managed to find a variant of u-boot with which can run Linux from external media on EDGE. This is the important step for creating Armbian and other systems for Khadas EDGE. 
 
 
There are images from Ubuntu to write to eMMC and to run from external media. I tried a quick test image with LXDE, and it works. I recorded the image to an SD card, connected it to Khadas EDGE and when I turned on the power, the system started automatically. You do not need any manipulation with multi-boot, it is already by default, when you disable the SD card , automatically starts the regular Android from eMMC.  I tried the combined version of the launch LE, the system starts, but while the KODI interface does not start, there is something to work on .... 

Managed to get a massive ear bleeding screech out of the audio jack after flipping bits around to enable/disable the microphone inputs folled by toggling rt5651 asrc enable/disable in the alsa mixer.  Trying to hone in now on how to get audio without mic feedback.  On the right track at least.

Copper shims make about 15C difference :-)

It is a research program, one of our professors from TU Muenchen cooperates with the Canadians (who operate the sub sea infrastructure).
The goal of this setup was to measure water quality in North Pacific (more specific, this special site) by deploying some light emitters and light detectors on two strings.
We want to learn about bioluminescence and radioactivity induced light, which both are kind of noise for the measurements intended later.
Let's say it like this: it's dark there, really, you have a perfect stable temperature, and it's easier to get things there (and back again) than going for deep holes in ice.
 
Moreover, we had to learn all necessary things about sub sea technics in a short period of time, including deployment technis (thanks to one guy supporting us, we made the job).
 
The setup is still operational (which I call success), and with some luck we will extend it with a third string next year, including some Odroid C2 based setups and (as we go for real fibre that time instead of good ol' copper lines) some more sophisticated electronics.
 
As soon as our paper is published, I can give more details (while I "just" did the electronics, there will be some more physics included )

Hi guys,
some months ago I implemented an Odroid C2 as readout controller for a scientific instrument.
Lot of people were kind and helped me with some problems with Armbian, especially eMMC and PWM.
 
Today, finally, we managed to have our instrument (two strings with several Odroid C2 and other stuff) deployed.
It is sitting now at 2628m depth in the Pacific Ocean, and will go operational the next days.
 
Here we are... I think I can announce the deepest Odroid so far (cry loud if I'm wrong :) )
In the picture you just can see the Titanium housing with two glass covers attached to the string.
 
Again, thanks for the fish :)

Here's a screen shot of the load presented to Armbian_5.65_Nanopim4_Ubuntu_bionic_default_4.4.162_desktop where I can run the cores at a higher level than on friendlydesktop-bionic-4.4-arm64-20180921. 

Thanks for the tips  The load is from BOINC with tasks from seti@home

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
 

ok 
I did it with armbian's build system, use userspace kernel config 
right now , kind of knowing armbian's build system 
btw
How to add board into armbian system?
I would like see gameshell board in armbian ,armbian is the best linux I've ever seen in linux world
 
it would be great to see gameshell board in armbian
 

 

I received a Drok Model UM25 tester, and started checking the voltage and amperage used.  I noticed that the NanoPi M4 when running at between 98% and 100% on all 6 cores draws a little over 5.1V and between 1.9A to 2.2A,  This is getting close to the maximum of 5A and 2.5A that the cable, (Anker Powerline+ II USB-C to USB-A 2.0 Cable (3ft)), and power supply, (Anker 60W 10-Port USB Wall Charger), are rated.
I shut down the 7 Raspberry PI 3B + devices also on the power supply and watched the NanoPi M4 use over 5.3V and 2.59A then reboot.
I looked up the specs for the NanoPi M4, it needs 5V 3A
The RaspberryPi 3B+ needs 5V 2.5A, (which is where the power supply and cables I am using are rated)
I ordered a 5V 4A power supply and a cable rated for 4A.
Until they arrive I an running the NanoPi M4 at 1.42GHz and 1.80GHz using the following commands
cpufreq-set -c0 -u1.42GHz
cpufreq-set -c1 -u1.42GHz
cpufreq-set -c2 -u1.42GHz
cpufreq-set -c3 -u1.42GHz
cpufreq-set -c4 -u1.80GHz
cpufreq-set -c5 -u1.80GHz
It is now using 5.2V between 1.61A to 1.82A and does not reboot and the temp is showing 53C
 

Where are you from? Odroid`s are easy to get. There`s a European sell point, an American, Korean, Australian. ...

The Tinker Board has got many faults. My first one broke, components just fell of. It`s powerhungry and overheats too quickly what makes the use of a fan needed. It does have good youtube and ok environment.
The Libre Computer Board ROC-RK3328-CC should be ok. I did not try it yet. I should look into getting some of their boards. I don`t know of the youtube playback on that. Could be awful,could be good.

The NanoPi M4 is awesome. It`s future proof with it`s USB3, gigabit ethernet, great wifi on-board, eMMC, 6-cores, .. I`ve never had a board that does everything so well from the start. Check my youtube for that one.
Cheers

Under 20$
the Raspberry Pi Zero W for 10$. It's very slow with only 1 core at 1Ghz. You can watch youtube with kiosk browser. And surf, very slowly.
The Banana Pi M2 Zero for 20$. A lot faster. 4x1.2Ghz. You need a good heatsink for it or it overheats constantly. Not very good video playback.
For 25$ the Rock64. Faster, better, but no wifi on-board.
A raspberry pi 3b+ is 35$ and again a bit better.
For your use case an Odroid C2 is perfect. Good Youtube playback, fast, doesn't overheat, ... That's about 50$

Those or the ones I have, and I can recommend. But for 20$ you will not get much.
You need to know that many sbc's don't have hardware acceleration for video playback in browsers. So expect choppy and low resolution video with most. The Odroid C2 does this best in Linux.
Also if a board only has 512MB ram then you want be able to open many tabs.

FriendlyArm also has got some interesting cheap boards.

I review sbc's on their desktop capabilities. Of all those I've got a video, except the C2.

Works in firefox. Even in Armbian. I don't know how. But it does. But Firefox does suck for surfing.
For that I use Vivaldi. There 1/3 lost frames in 1080p Youtube. Chromium 2/3 lost frames. Firefox 0 frames lost. All video works perfect. I even use it as video player on the NanoPi M4.
For me the NanoPi M4 is the perfect 2nd desktop pc. It's very fast. It's got an amazing heatsink. It's stable, haven't had 1 crash with it in hundreds of hours use. I've tried many different sbc's on there desktop capabillity's. The Odroid C2 was the best until the NanoPi M4.
Tinker board does ok in video, but many things don't work. I've tried it again this week, and it even got worse. I need 3 different OS'es to be able to do everything.
To my knowledge not many others than the C2, tinker, rasp and RK3399 have HW acc in Linux. The Raspberry sucks to work with.

LMAO, clowns and scientists shouldn't have an iPhone.
Background, to reduce the footprint, the quatz is replaced by an MEMS timing oscillators instead of a quartz. If this thingie gets now flushed with Helium, the MEMS micro-mechanics doesn't work properly anymore and the iPhone crashes.. Only solution:
 
 
Edit: might be interesting what happens when you flush your iPhone with Argon.. (heavier than air) Someone has one spare? I can test it..

I`ve got exactly the same adapter and it works immediatly here.
Armbian Bionic kernel 4.4.162-rockchip.
Are you using the volume control? Here it finds the adapter and puts the sound thru the moment I connect.

Well, that is in a sense what is done now with "board families". All the boards in the same family share the kernel and most filesystem tweaks, and differ only in the device tree and some adjustments for specific hardware. But it is only possible when all the boards share the same SoC or a very close one. With completely different SoC's, that is not possible, each one needs a different kernel. Notice that all different boxes supported by balbes150's images have some Amlogic Meson SoC, and that is why they can use the same image with minor tweaks.

People of firefox don't care about Linux on ARM devices. It's been broken for a long time on armhf. Even on arm64 it crashes constantly.
This is a fork of Chromium. But better optimised for ARM. I don't know how, but on most arm devices the video playback is a lot better than Chromium. This without using hardware acceleration.

For example, on my NanoPi M4 I get 2/3 lost frames 1080p. While on Vivaldi it's only 1/3 lost frames.
I use it to surf on most devices since it's fast and stable.
Greetings.
 

It's quite cool. Not really multitasking. But instead of using delay what stops everything you check if the time has passed long enough to start a task. So you can do other tasks during that waiting time.
But when a task is busy you can't start another task. That 2nd task will start when the 1st task is done.

Very simple but effective. Why didn't anybody come up with this earlier?

I assume it comes with SPI, so.. testing a small display on breadboard is easy.. And my famous balance example.. normally I need the measured weights when I write lab journal on my normal computer.. so, display is not really needed on the balance.. it still has one.. I just need it stored.. It somehow replaces the god old paper..  okay I'm working on a RFID implementation as well.. but that's just to have some sort of an inventory system but that's future..
 
as soon as you integrate area under signals a regular python makes things a way easier.. python has cool modules for such funny stuff. Indeed a bunch of this stuff could be achieved with ESPs but you must be somehow a masochist to do it.

I don't think so, IMO the nanopi duo was somehow 'useless' due to crappy wifi. So without a carrier board you didn't had a sane solution to drive it headless. AP6212 will fix this mostly. Having a board which is breadboard capable by default makes it quite easy to set up some testing. And once your small 'pet project' works as expected you can even solder it to something like this:

or you etch your custom pcb for a few bucks (it's a way cheaper than it was in the past). Those RPi compatible headers always need an adapter or a custom made adapter or PCB to get it usable for such tasks. Still wonder why breadboard like hats aren't default for all those boards. IMO something like this:

should be in every boardmakers store by default (with the default size for their RPi a like boards). Sell them for 5 bucks each and you'll sell a bunch of them.
Don't get me wrong, the ESP32 is a great board (especially some of the drawbacks on the ESP8266 were properly solved, e.g 512kb ram is a great enhancement for micro-python on it). It's even possible now to have somehow a 'nice' web-interface on it. Storing data on the SPI 'somehow' works but it's not as convenient as on a 'average Armbian board'. My ESPs mostly cache data only for a short time and then send them over mqtt to a linux machine where you've great frameworks for handling those data.. most of it would be possible with an ESP as well (there's not much fancy numbers crushing) but I'm simply to lazy to program such stuff in micro-python or 'C++' (aka arduino for ESPs). As soon as you want a more enhanced web-interface you're soon getting to the ESPs limits (e.g. user authentication, graphs, getting out logs - everything is possible, but it needs a lot of work to achieve). Storing on SD-Cards on ESPs is somehow archaic.. It works but my I like to pull data from my stuff without rejecting the SD-Card and doing this on ESPs is IMO hacky.

To summarize, it's a BPi-M2-Zero with different pinheader...
