Yes, you can boot off USB.
You need to either have a U-Boot image on the SD card or on the eMMC.
From there, if the system partition is not found on the SD Card or the eMMC, it will try to look for it on the USB drives that are connected.
 
My system is booting from a USB drive at the moment - the U-Boot is installed on the eMMC (I erased the partition table afterwards, but the bootloader is still there).
If you zero out the eMMC, you loose the bootloader and you need to boot from an SD card. I belive that once we can install the bootloader to the SPI chip you would be able to boot directly from the USB.
 
As @TRS-80 mentioned on the post above - the tool to use for moving your current system from the SD Card to either a USB or eMMC is "nad-sata-isntall".
Today, there was a new post on the wiki page for the Helios64 about the process.
 

Definitely nerd porn.    Thanks for sharing pics and progress, Igor.

Today I had the pleasure of benchmarking an ARM64 server.
This server has been made available for Armbian to test native ARM64 image building.
I knew nothing about the server. Nobody told me any details.
So everything was an adventure for me to find out. I got SSH access, so my research began.

A lscpu informed me it had 32-cores all clocked at 3.3Ghz. 
 
cat /proc/cpuinfo confirmed these 32-cores
 
Checking on what kernel we're on. Ubuntu Focal 5.4.0-52-generic. 
And how much memory. 128GB RAM.

So first thing I wanted to know, how does one core perform with 7-zip benchmark?
The record I had seen until now was from the A73 cores from the Odroid N2+ clocked at 2.4Ghz. 2504MIPS decompression.
So :
taskset -c 31 7z b
 
This beats the Odroid N2+ its A73 cores clocked at 2.4Ghz. 2763 vs 2504MIPS decompression. 
This also tells me these cores do not perform as good per clock as a high performance core. 
While doing the single core benchmark I checked the sensors to know the wattage and temperature.
 
CPU power is about 20W for a single core tasks. 
Without a load the CPU consumes between 10W-15W. So in total it consumes a bit more than 20W in idle.
Temperature never went under 49C even after +5 minutes in idle. 
 
Of course, the next thing to do is an all-core 7zip benchmark. 
This gives an amazing result. Way higher than anything I had ever seen on ARM.
 
85975MIPS decompression. This is amazing.
Best I had seen was 11000MIPS of the Odroid N2+. So this server does 8 x better than the N2+. 
Tho, I must say. 7zip does bad with unequal clusers. The N2+ has a great difference in cluster frequencies. So it performs worse then expected here. 

The wattage went a lot higher, up to 110W. And the temperature rose quickly up to 75C in seconds.
 
To test the internet connection I downloaded an Armbian image multiple times. Sometimes it was as low as 3MB/s. 
Highest average speed I've seen was 12.5MB/s
 
Next test. BMW Blender render benchmark. 
Here the fastest I had ever seen was by the Khadas VIM3. That did it in 42m51s.
I haven't done this yet with the N2+ in Armbian. In Odroid's Ubuntu it was a little slower. I expect it to be a little faster than the VIM3 in Armbian Bionic. 
This is a tile based test. So every core gets its own task, until all tiles are done. 

Well, this ARM64 server did this in 8m27s. 
5 x faster compared to the Khadas VIM3. 

For this the wattage didn't go over 85W. But the temperature did rise to 83C. So it started to throttle. 

@lanefu already had done SBC-Bench on it when it was free. So this I didn't have to do myself.
http://ix.io/2Dcc
Here we see a lot. For example the CPUMiner did : 81.0kH/s 
The Odroid N2+                                                         : 14 kH/s         5.7 x less 
RK3399 does a maximum of                                     : 10.23kH/s     8 x less
Odroid C2 clocked at 1.75Ghz                                   : 4.65kH/s       17 x less

So this server clearly can move a lot of bits around. 
Now, what is this server? Ask google if nobody else tells me. "32 core ARM server 3.3Ghz"
First answer : https://www.theregister.com/2018/09/18/ampere_shipping/
That looks like it is this CPU. But still I can't find the exact name. 
2nd answer : https://www.servethehome.com/ampere-32-core-64-bit-arm-chip-x-gene-3-ip/
So this is the Ampere 32-core 64-bit from X-Gene 3 IP.

Here the wikichip : https://en.wikichip.org/wiki/apm/x-gene/apm883832-x3?fbclid=IwAR0ljCQ61DY8Zwh_VyZd0fQH43dmPUTJA-CGLiQKYqU2fWwszFm1CPjH6Zo

This supports up to 1TB RAM. 8 channels @ 2666Mhz. With a maximum memory bandwidth of 158.95 GiB/s.
42 lanes of PCIe Gen 3, with 8 controllers
– x16 or two x8/x4
– x16 or two x8/x4
– x8 or two x4
– Two x1

4 x SATA Gen 3 ports, 2 x USB2. And a TDP of 125W TDP.

For me this is just an awesome thing to behold. I use ARM for almost everything.
The NanoPi M4V2 is my main desktop computer.
It isn't as powerful as my PC, but does the task for 10 x less power consumption, while being completely silent.

But when I need a big CPU, it isn't enough.
Even the more powerful Odroid N2+ isn't powerful enough to render long, +20minutes 1440p video's for example for my Youtube channel.
So then i need to use my x86/amd64 PC. 

Today I have seen and tasted the future. 
While this doesn't use the most modern Cortex/clusters. And it is only 16nm.
So there is still a lot of room for improvements in performance and lower power consumption. 

ARM for desktop is possible, and ARM servers for big datacenters is possible(AWS). I have seen the future, I loved every second of it. 

Here benchmarks compared to my SBCs

 

Greetings, NicoD

This software is provided you in "as is" manner.  If you want better functioning, you will need to support the project with more then nothing. We also don't like "customers" that:
 
- complains and waste our time.
- contribute nothing to project and software development,
- doesn't respect free support - dealing with your problems on our private cost,

Sorry for beeing direct.
 
 
Read this - it will explain you how things. Board is similar but the difference is that your board vendor is actually helping us a bit, while our resources have limits.

Good news! I got to compile a highly optimized ffmpeg binary from a current git, with XU4 tweaks, that is able to encode two simultaneous 1080p@25, as long as the source bitrate is not excessive.
 
You can download and give it a try from here. It is completely static, so you can install it on any distro. It will install the binary in "/opt/ffmpeg-xu4/bin/ffmpeg", and a symlink "/usr/local/bin/ffmpeg-xu4". Therefore, it can be installed along the system ffmpeg without conflicts.

TL;DR: Odroid XU4/HC1/MC1

Sorry, I didn't see this post before. I have a jellyfin server on a Odroid HC1, working like a charm since long ago. HW transcoding can do 1080p with no problem. I have special ffmpeg packages for Armbian buster, in case you want them.

After all the harm that corporation has done to open standards and free software? Not funny.

We added acronyms to the forums. Commonly used abbreviation like SoC are now marked and their meaning can be highlighted by simply moving the cursor over it.
If you do have ideas for missing acronyms feel free to comment here:
 

So far, this is the closest thing to what I have been looking for. If it only supported ECC (or that was perhaps made available as an option) it would be really interesting for ZFS. Pity.
 
If anyone has found a small SBC (not gigantic 1+U data center thing) that is ARM based with ECC memory, please let me know.
 
EDIT: Apologies, I just now saw this:
 
 
When and if that actually comes to market, and is well supported in Armbian, you will have a customer!
 
Please do not include anything stupid like non-free, proprietary firmware that would preclude the use of such nice hardware in freedom.
 
If you can manage all of the above, you will not only have a customer, but a very vocal proponent!

@Jijo,
 
I found the post that @NicoD mentioned above, in literally seconds looking around the TV Boxes forum, and I don't even own a TV Box nor trying to get one working, etc. Please look around, search, read on your own for some time before you make posts looking to be spoon fed.
 
In defense of the first 2 posts, the development of the above did not really begin until 2019-12-03 as can be seen by the post date.
 
At any rate, since this thread is not really providing anything useful (other than @NicoD redirect above, you should probably thank him BTW) I am locking it so people don't continue to post in here.

A few months later, and I have a little more time, so decided to volunteer to help tidy up the forums.
 
I never directly received a reply to this question, but someone must have heard me because I was just looking today at the Donate page, and now I see (in addition to monthly PayPal option from before):
Bitcoin address Amazon wish list (for purchasing hardware) Contact form (for setting up bank transfer, invoice option for companies, etc.) I for one was happy to see additional options and just thought I would share what I discovered.
 
You like Having Nice Things(tm)? Consider supporting Armbian today! 

Recently we been finding some very clever spammers who register, make some post(s) that sound at least somewhat on topic, and then come back days or even weeks (!) later and edit them in order to insert spam links. Some examples:
 

 
Some times they put them alongside otherwise legitimate links:
 

 
Other times, they sneak them into quotes or lists, etc.:
 

 
Now, above examples have red background from being deleted (which is not how they will look to you normally) but you get the point.
 
There is no way for us currently to detect this kind of spamming, without enacting draconian measures of moderation, which we are certainly not going to do. So instead we ask for your help. The only way to really find these is to happen upon them while browsing the forum. If you see one, please click on the little flag at the bottom and a Moderator will take care of it. It only takes 2 seconds, and you can help out in keeping the forums a nice and useful place.
 
I also want to mention that something does not have to be Spam, or otherwise "bad" for you to Flag it. Anything that you feel deserves Moderator attention, such as off topic, or a diverging thread that needs to be split up into 2 or more separate topics, etc. can be Flagged.
 
Any forum Member can do this, it requires no special permissions whatsoever.
 
Thanks for your help!
 
Note: This post is geared toward every Member / user of the forums. The corresponding post geared more toward Moderators about how to deal with these kind of posts (once Flagged) can now be found here.
 

Don't confuse freedom and mess (permissiveness), it's not the same thing. I didn't see any arguments for what ordinary users need to edit messages after 1-2 days. Changing the text (not correcting typos or errors) after a while is a bad procedure. People have already read the message, may have responded to it, and no one will return to the corrected message, so there is no point in changing it. There is a good rule of thumb, before clicking the submit button, read what you wrote. This is not respect for everyone, send obviously crooked messages (so that others would try to understand what is written there) and then constantly correct them.

OK, even if that is true, I don't understand why not to do it? It requires zero effort on our part? And makes one more hurdle for spammer, but not legitimate user.
 
 
Thank you!. This is what I have seen as well, hence my arguing so strongly for it.
 
There is "theories" of what spammer could do, and then there is data (that we have) of what they are actually doing...

Maybe but... 4600 validating accounts disagree
 

it's not the distributor - it's the company behind NanoPi boards..
 
IMO the whole thread can be moved to: https://forum.armbian.com/forum/31-sd-card-and-psu-issues/
 
NanoPi M4 being not PD-compliant and therefore might be troublesome is mentioned on the dowloadpage:
 
linking to
btw @Igor or @lanefu we might add the same disclaimer from nanopi m4 to the orangepi 4 cause this board will have the same issues (I updated the thread but forgot my credentials to the WP admin board to do it on my own - feel free to remove my rights there anyways I didn't do much maintenance of it and honestly don't plan to change that in the future).
 
(hidden cause not really an advice more a hack to maybe achieve what you want but not what you should - having a sane powering for your setup)
 
3 amps at 5V is sufficient for the NanoPi M4 in most scenarios I had. But if you look at their "expansion hats", the USB3 and the SATA "hat" provide a barrel plug and for the sata hat additionally a ATX12V 4 Pin connector indicating that even they do not recommend using USB-C for such set-ups.. 

Sorry for the other topic. I had made it before you replied and didn't know how to delete it.
 
Now things seem to be clearer.
I used to power it with an 5V/3A AC/DC power and a USB cable which is sold by FriendlyElec, a distributer of NanoPi M4
https://www.friendlyarm.com/index.php?route=product/product&product_id=234
but the power supply for boot was not enough so the USB device was seen as USB2.0 after the boot.
 
Then I changed the power supply from that to a regulated dc power supply and power the pc via USB type-C connector.
This resulted in what I've wanted, I finally got the USB3.0 connection at boot.
It it strange but FriendlyElec's official power supply system isn't that good.
 
 
 

I think very strongly that validating email should be (one of?) main steps to graduate from Validation -> Member. Anybody can put in whatever they want for an email address, it's all BS until they have validated it. And in the meantime they can be posting already...
 
Most of spammers I see, never even validated their email...
 
Some number of Likes (perhaps along with other criteria like post count, and/or time on forum) I think is probably a good idea for this "Trusted Member" (or whatever we want to call it) intermediate level. I think Likes especially are hard to fake.

Here is an update about multimedia integration: I have been trying to make all the Rockchip-legacy stuff work on Buster, and I am not able to get accelerated X desktop. I cannot find the exact cause, apparently something is making eglInitailize() fail. My guess is it has something to do with mesa libs, but could not debug the exact cause.
 
In Rockchip, they are working in a completely new approach, using exa instead of glamor acceleration. They need to use for that another particular feature of their SoC's, called Rockchip-rga, which in turn needs its special kernel driver and userspace libs (similar to their rk-mpp). So far, it does not seem to be working in the 'stable-4.4-rk3288-linux' branch we are using, and the stable-v2 branch does not compile ATM. I wasn't even able to make it work with their own linaro image.
 
So my proposal is that we keep the download option of Bionic Legacy Desktop for all the rockchips, with the link to the media-script thread, for those who need to use some of the features that are still only available in legacy kernels. ( @Igor would it be possible to keep it for a while? Bionic still has three years of support ).
 
With newer releases (Buster, Focal), we will focus on mainline, and hopefully at some point legacy won't be necessary at all.
 

Currently amlogic s922x or A311D are the most powerful socs (4xA73). The first one can be found some tvbox like beelink gt king or ugoos am6 and the second one in khadas vim3.
I think that most rk3399 boards have better supported than amlogic ones.
 
For your second question, it mainly depend on your use case.

Hi, writting from my box. I use the latest image from balbes150. base don kernel 5.5.1 with meson-sm1-sei610.dtb. Trying to use the color trick for g12 board doesn't work for me, the board does not boot at all. Without considering the color problem, the desktop experience is smooth and the soc stay cool even if I have remove the heat sink (<50°C without heavy loads and go up for 60°C when watching test videos on mpv or chromium).
 
eth0 is visible but not able to send/receive data. wlan0 not visible, I use an usb dongle. Bluetooth seems active but not able to detect a bluetooth audio speaker.
 
Stop here since the blue color is not comfortable, but a more detailed report can be found here: http://ix.io/2bEh
 

And I explained where is the actual problem  And we have to fix on the process levels.

Workarounds are useful, don't get me wrong. Thx.
