OK, good luck! Note, you may want to contact FriendlyElec before putting the board into the oven to let them know that one of your boards seems to be dead and let them know what you've tried and that you're planning on trying the oven. Maybe they'll simply want to send you a replacement one and will ask for this one to be sent back there for inspection. They've already sent me some replacement hardware for early defects, they're really nice.
What avenue of contact did you use when you got in touch with them? I tried techsupport@friendlyarm.com but no response so far.

That's a really good idea. I was considering placing another order for additional boards but I was getting cold feet - but if they replace it that will be a great sign.
So far not looking good for booting, although I seem to be getting proper voltages at all of the gpio pins I have tested.

You should try to connect a serial adapter to its console port to see if it emits anything at boot. If it doesn't, it's probably dead.
Thanks for the thoughtful post. I am going to try the items you brought up, starting with giving the board a few days off to fully settle. If all fails I will try to reset the connections with the oven method but I will treat that as plan C. I will post a followup later with whatever ends up happening.

I've had my 14 boards going mostly continuously for about six months now with some occasional scheduled downtime.
I am finally having trouble with one board and I am trying to determine if it is dead. I just noticed that I wasn't able to find it on my network out of the blue a few days ago. The problem may be related to a power outage I had but I'm not certain about the timing of when it went offline.The board power light still works and I am able to power external items with the GPIO pins (fan) with no issues. I cannot ssh onto the unit because it doesn't show up on my network. I am not getting any display output from the HDMI either. I have tried re-imaging the OS on two different Class 10 U1 micro sd cards and had the same results on both. I am leaning toward a dead board but is there anything else I should try before I throw in the towel on the board?
Also, I am now concerned about the health of my other boards and think I might be running them too hard/hot. I think my average temperature has been about 63 degrees Celsius. I have always been curious what an acceptable temperature is for these.
The temp usually shows up as red text instead of green on that flash screen on login. Does that red/green threshold have any basis on anything or is it just arbitrary. I run my boards pretty hard but I will throttle them back a bit if I am risking their longevity. I'm also probably going to do the copper spacer mod that tkaiser posted about now to see if I can get my temps down.

If you want to test latest builds, it's also fairly ok to download just any available image for this board, switch to beta repository and update. It will work in most cases.
Sorry if this is too noobish but how do I switch to the beta repository?

Are hugepages enabled by default for the nightly repository images?
I do seem to have gotten it to work with this command:
sudo sysctl -w vm.nr_hugepages=128When I run this, hugepages seem to be on:
cat /proc/meminfo | grep Huge -

Hi. I have an issue configuring the board: no hugepage configured. I installed the command line Ubuntu. No I am in command line via SSH. Everything is ok. With a NanoPi Fire3, OrangePi Pc2 and an OrangePi Zero H5 I had not this issue. The folder /sys/kernel/mm/hugepages does not exist; the folder /proc/sys/vm has not the value or file that tells how mutch is the hugepages amount.
What is the process for enabling hugepages on NanoPi Fire3?

@datsuns double check that the thermal pad they provided didn't move when you were installing the heatsink.
I know when I first got it I put the thermal pad on then placed the heatsink without putting the screws in the heatsink first. This caused the thermal pad to move off slightly. Also thought I killed it by pushing down to hard and all
.
Temp wise low usage you might get away with no active cooling but this thing does pack a bunch for its size. And I will add temp wise it does handle better then raspberry pi 3 due to the massive heatsink.
I've tested this for 4 days straight on xmrig and it sits @ 58c stock speed all 8 cores. 29.5hs btw for cryptonight.
Just make sure when you shutdown under armbian you pull the power plug because it doesn't shutdown right and CPU heats up. Under friendlyarm it does the same btw only power off button works. So sudo halt or logout doesn't really shutdown right!.
I'd like to do some benchmarking with xmrig and explore overclocking now that we're approaching the end of the summer heat.
Can you share your xmrig build instructions? I am not finding anything concrete on the github for an armv8 aes support.
EDIT: I did get xmrig running using the standard build instructions for Ubuntu 16.04 (using gcc 6.3.0). I am getting a consistent 28.2 h/s with those build parameters and no overclock. Any suggestions for a more optimal build are highly appreciated.

Is there a good resource for what's currently being developed by the major SBC manufacturers? I am curious about what is being developed and when it is coming out. I'm thinking about expanding my cluster by another 10 or 20 nodes but I don't want to invest now if something great is going to be released soon.
I am most interested in FriendlyARM and OrangePi boards as they seem to have a good performance/value ratio around the $35 price point but I am interested in what all major manufacturers are doing.
Is there anywhere to read about development? Or is anyone here privy to what's next for low cost ARM based SBCs?

For those of you running a large SBC cluster - what is your solution for powering your boards.
I currently have a cluster of 18 boards that I am powering with several multiport usb chargers. My setup does work well but I am looking for alternative solutions. I'm thinking of expanding my cluster to 50 or more boards and I don't like the prospect of purchasing so many of these multiport chargers as they're a little bit expensive. And I also don't know about the long term reliability of my current setup as I have only been going for about 2 months now.
I would love to hear about and see other people's SBC cluster powering solutions.
EDIT: I'm open to all options but some kind of rackmount solution would be best. A lot of the rackmount stuff is very spendy - and I honestly don't mind that if it can power a lot of units. But I am mostly curious about skipping the powering alternatives that don't use the USB port at all. It just seems the best solution when powering many devices simultaneously.

Update
All my boards have had continuous up-time for a full month now with rock solid consistency. I am really happy with this board so far and would recommend it to others. Just make sure the cooling is adequate and you will be happy with performance.

As for cooling i use https://www.amazon.co.uk/ELUTENG-Computer-Portable-Radiator-Ventilator/dp/B071CL82G9/ref=sr_1_18?ie=UTF8&qid=1528834494&sr=8-18&keywords=usb+fan. I have mine stacked so no need for fans for each unit.
All nanopi fire 3s are around 55c at stock freq under full cpu load.
Also be very very careful with that 10 port power supply. I know mine gets warm running 5 fire3 and the usb fan at present so do not go to the limit with the power supply as it will most likely melt. Always stay under the rated wattage!. They are not designed for prolonged high wattage usage.
I have got my fire3 stacked in https://www.amazon.co.uk/ILS-Clear-Acrylic-Cluster-Raspberry/dp/B0768DDTKD/ref=sr_1_2?s=electronics&ie=UTF8&qid=1528835367&sr=1-2&keywords=raspberry+pi+stack+case
You will need to drill new holes to mount them btw.
If you do get problems with under voltage or shutdown etc check the usb cables. So many times with the raspberry pi i have got under-voltage warnings and 95% time it isn't the power supply but cheap cables or long length usb cables that caused the problem.
Overall I am running a very similar setup to you but I have 16 nano pi fire3s across three different anker usb multiport chargers. I have 6 fires on a 6-port, 6 fires on a 10-port and 4 fire on a 5 port. Also each of my fires has it's own fan. But now with what you're saying about the power supplies I guess I am going to switch one of my fires off the 6-port over to the 10-port.

Well, all these multi-port chargers never deliver up to the amount they claim. You can safely expect 50 to 66% though, which is not bad overall. I removed the current limit detection in mine to stabilize the output for the MiQi farm. That said, I never managed to pull more than 1.6A in peak from my Fire3 at 1.6 GHz under 1.25V, so you have some headroom I guess. You need to consider that when the board is hot, its DC-DC regulators' efficiency starts to drop and to turn the current into more heat. Thus it's more important to measure the current when the board is already hot if you want to be pessimistic (or realistic). That was the case for me at when I measured 1.6A. Quite frankly, you're worrying too much : if when loading all the boards it still works, that's fine. If you want to buy more boards, then buy them and plug them to your charger until you find the limit. The charger will either cut one port or completely shut down. Then you'll know how many more chargers you need to buy depending on the number of boards :-)
Ok, I'm going to just keep adding boards if it continues to work. I was more worried about it throttling down the performance of the boards before they shut off but it sounds like that's not what it would do.
You seem knowledgeable about the board so what do you feel like is a good stable operating temperature for these units? I am running active cooling and no overclock (1.4GHz) on all of my fires and I am seeing something between 66-70 degrees C on average when I periodically check on temps. This can of course vary depending on the ambient temerature in the room as well. If I tried out a mild overclock what temperature range would you start to get concerned at? It sounds like you are running yours at 1.6GHz - what kind of cooling are you running? I'm currently using small fans running on 3.3v. My setup is close to my desk and I have found running them at 5v is on the annoying side so I'd like to keep them at 3.3v.

No, in my experience, the board will either hang, switch off, or reset when undervolted. Usually you need a voltmeter to check the board voltage under load. If you don't have one, you'll need to verify that they're all working fine (ie: ping them). The best you can do is to run cpuburn-a53 on all of them at the same time. If nothing fails, you should be fine.
So far I have experienced no problems - no hangs, switch offs or resets. I'm giving each unit the recommended 2 amps and I just want to know what I can get away with. Everything is running headless with a heavy cpu load and nothing else.
Specifically, I am using this usb charger:
https://smile.amazon.com/gp/product/B00YRYS4T4/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1
Since it maxes out at 12 amps over the 10 ports I am only utilizing 6 of them to give each of my nano pis the full 2 amps. I am open to experimentation but I don't want to hurt any of my units or sd cards.
What do you think a safe minimum amps is for a high cpu load and not much else?
-
I now have quite a few of these boards running and I am powering them through Anker mulitport usb charging hubs and all seems well.
This might be more of a general Armbian question but if I wanted to verify that my boards aren't experiencing any undervolting, is there a log file that I can look at?
I am just being cautious now - everything seems to be running in tip-top shape with no issues.

When you say it heats up, what exactly do you mean? Like the cpu works harder when you attempt a shutdown or just continues to do what it was doing?
Also, does this come into play for reboots at all or do they function normally? I pretty much run my boards 24/7 so it's not really a big deal but I do occasionally reboot them so hopefully that does what it should.

That's quite different from what I'm seeing given that I had made my own enclosure out of cardboard with no air around it! Of course it heats but not that fast, despite the fact that I overclocked it. If the fan helps, it's probable that you're not having a good contact between the heatsink and the CPU. Verify that the heatsink is very parallel to the board, it's possible that it touches only by one angle.
Ok, that's what I was kind of worried about with my initial thoughts. the problem is that the cpu is so short that you can't make direct contact without the fat thermal pad. With the fan it's been really good though and I don't mind the 3.3v draw to keep it cool. And it has been absolutely rock solid for hours without rising above 59 degrees so I am really comfortable with the setup.
Also note I am running all 8 cores at 100% continuously for hours. Have you replicated that type of scenario with just the heatsink?
I really like this unit - it's kicking ass for my application and I will probably get several more for other things.
-
Well I added a tiny, cheap fan running off the 3.3v pin in conjunction with the included heatsink and thermal pad. At 100% CPU load I am getting a very stable 58-59 degrees C according to armbianmonitor. This is with an ambient room temp of about 23 degrees C.
It's like night and day compared to the heatsink alone. I guess these boards really like to have a fan. So if anybody out there wants to run their board hard - get a fan asap!

I must confess I absolutely don't remember what I used given that I always have everything I need for this. It's possible that I naturally placed a thermal pad in between. I don't remember having opened a thermal paste tube. Or maybe there was a pad with the heatsink. But definitely I didn't put raw aluminum on top of the CPU die without anything to make good contact in between.
The included thermal product is more of a pad than a paste, I guess. I set it up with that and I am running some tests. It gets super hot super fast under 100% cpu load and shuts down at 100 degrees Celsius. I will probably do active cooling - not impressed with the heatsink even though its kind of large for such a small board.
And you mentioned before about the three throttling temp threshholds - where do I edit those? It seems to shut off before it can throttle down right now.
-
I just got my nanopi fire3 in the mail today. Looking at the heatsink and the board layout and the physical height of the soc, how are people mounting this? Is anybody happier with an alternative to the thermal paste? Maybe something like a copper or aluminum spacer instead? Or maybe the thermal spacer works well?
-
And one more thing. The unit looks a lot smaller than the standard raspberry pi form-factor. Do the those mounting holes correspond directly to those of a raspberry pi?

I'd say around 2 weeks.
The default heatsink is enough if you're not running at 100% CPU full-time. For my use cases, it's mostly a network endpoint and I can run it at 1 Gbps without problems even with the board confined in a cardboard made enclosure. But if you run with all CPUs saturated, you'll reach around 5W that need to be dissipated one way or another. The default heatsink and the PCB are not large enough to dissipate 5W at a low temperature. I significantly raised the temperature thresholds (113, 115, 120) to prevent it from throttling too early. Note that these thresholds are higher than the datasheet's (85°C in commercial ranges). But the thermal sensor supports up to 125°C so probably there are some industrial/military grade variants with higher ranges. For a personal project I'd say you have some headroom. For a commercial product, you probably don't want to play with this and you may have to use a small fan, or to place a thermal pad behind the board against a metal enclosure.
Ok, this is some good info and I will do some testing when it arrives. What do the three values here represent (113, 115, 120)? I assume these are values you picked and are celsius temperatures - is 113°C the value you chose before it starts throttling performance? And is 85°C the default cutoff for throttling?
Based on your time estimate my board should be here any day now so I am getting pumped to try it out. I'll do my own temp testing under 100% CPU load with and without a fan.
-
Can anybody that has this board tell me how long it took to receive after it shipped (ordered directly from FriendlyElect)? I'm dying to test this thing out but haven't received it yet.
Also , if anybody is currently running this board for a long-term project and has a cooling setup that they are happy with I would love to hear about it. From the OP it sounds like the incuded heatsink alone isn't really sufficient.

I see in the download notes that there is a MAC address issue and I have also experienced it with my testing. Is this a hardware issue or is it on the OS side of things? I also had something similar with the aml-s905x-cc and I seem to remember I partially fixed it by hard-defining a MAC address.
If it's on the Armbian side of things I will just wait for the stable build to release but otherwise I would like to fix it if I can.
Also, does anybody have a recommended heatsink size or even a specific amazon listing they can point to?
