Excited product! Nice price!
I hope that it has lower cpu temperature for passive cooling.
It is important for fanless embedded application.

Great work, wondered when something this good would be announced to replace my stalwart 3 -C2's.
I certainly would like to order one or 2.
Will pre-orders be accepted?

Fascinating. This has everything I'd want in a C3 except preserving the form factor. I'll have to comfort myself that the GPIO header is the same.

I wonder if it will be possible to throttle down the RAM, like it is with the C2, to save power. It'd be even better if we could do so on the fly without rebooting but I'm not holding my breath.

How soon will one of these be on the odroid-bench so we can log in and run some benchmarks? :)

@campbell - for the fun, the XU4 has patches (to be merged on 5.1 or 5.2 mainline kernel) for dvfs (devfreq) support for memory, and fixes for PM and sleep mode :)
PS: gpu also supports devfreq :D

I do believe this will be a "yes" from me too. April can't come soon enough.

I was a little disappointed with the 90mm footprint since I wanted it to fit on a 2x4 stud in my wall. But I think that little .043" is like smaller than 1/16" which is probably like the size of grout between small lugged (those edge nubs) ceramic tiles which is very small, and since the magnetic push-latch on the wall cover already comes out a little bit (to allow for the "push"), I expect it may be alright.
I'd want to see the other side of the heatsink to see if there are thru-holes where standoffs can be placed so I can mount it to the stud.

I am anxious for it, as I've been without my server ever since I fried my xu4. It was a question as to how long I could hold out for the N2 before getting one of the RK3399 boards like from radxa.

Wow! Yesterday could not access the internet because I was busy all day. Great news. Pricing is spot on. Need 2 things now.
a) Benchmarks (especially opencv for my use case)
b) CAD or other design files. For working with some cases. (would love to get hands on some engineering samples but it is too much to ask at this point)

Black emmc

Unread post by noonespecial » Thu Feb 14, 2019 2:42 pm

I have a C2 purchased on ameridroid from 2 years ago along with the black emmc.
Im really hoping my black 128gb emmc is gonna work on the N2. Can anyone confirm this? Im thinking yes because its compatible with H2. But I would really like to know for sure. Super excited about this board.

Please visit the link to see the naked heatsink. On the surface of the heatsink, there are 4 x M3 through holes that can mount standard M3 PCB support.

I just really hope that there will be an Android TV build available for the N2. This way we could get a cheaper NVidia Shield TV alternative which can be used for gaming and easy multimedia consumption of Netflix etc.

@kaiomatico: why use Android TV? I have a TV box that is running a mixed build (Android TV and regular Android) and I can tell you for sure that it is not worth it. DRM will only be Level 3 and Netflix and all streaming services will only have sub-HD resolution (960x720). I plan to slap a LibreElec/OpenElec build on my N2. Android has a lot of issues that Linux does not have.

@odroid was so generous to send a lot of development boards to Team CoreELEC developers. We already started working on it and we are confident to have a working image for Odroid N2 soon. I will buy a lot of those boards personally to replace my C2/LePotato's. I'm sure we can get Full HD Netflix with SW decoding working.

I still hope we will see an Odroid C3 with maybe S905X2/2GB which would also be sufficient for a CoreELEC image.

Can we get design files for the SBC? Also, I am interested to know if the tensorflow lite GPU support runs OK on the G52 or not. Anyone getting the engineering sample willing to test and confirm?

Likely sample receivers will run most anything they can copy paste, but also you can just run it yourself "early next week" via ssh on the "ODROID Bench".

Excellent, though the mounting holes look to be really close to the edges making drilling into the stud difficult if not impossible, but I have another solution for that.

Ugh! Another thought just came to me regarding the dimensions... :(
I first saw this announcement on cnx-software where I read about the 90mm.
The thought now was whether or not it included the heatsink space, and going back to the specs on page1, I see the heatsink makes it 100mm and that nearly 1/2" beyond a stud width is likely the deal-breaker for me, I'm sad to say.
In fact, I do believe it IS the deal breaker because the one edge of the heatsink, pressed against the back of the drywall at the back would kick the mounting holes on the opening side of the wall further out, thus making mounting on that side impossible... for the most part.

Basically my solution above would have been take some thin but rigid material, cut it to the size of the heatsink, drill holes in it for the heatsink, then some more holes for the stud. Screw standoffs to that material, then screw it to the stud. Then place the heatsink over it and mount the board.

But again, that extra space is the killer for me. I really want the wall pieces to be as flush as possible, but being pushed out that extra 1/2" is too much for me. I guess the option left for me is that radxa board.
I just measured the distance for that push latch and it's less than 1/4". I could make those wall pieces flush with the wall without the push latches, but would have to have some sort of handles so I could remove them.

HK/ODroid had been really great, and I enjoyed both boards I had and will continue to keep tabs on what you're doing/producing in the future.

There should be room for 2 if you just mount it sideways.
Use a bracket or drilling a hole or 2 in the soft extruded aluminum should be trivial with a hand drill (one could use a table fork with a bit of effort).

I think one could mount 132 between an average pair of studs.

I was speaking of my particular case scenario. The area I had allocated was sectioned off into 3 parts (and that is not the entirety of ceiling to floor), and the bottom part that houses the server also is home to other components mounted to the drywall. That was the appeal of the small SBC which I could mount to the stud. Both the U2 and XU4 and even my microcontroller I have in there right now fit on the stud.

N2 looking really good, but for future designs please consider putting 2 Gig-E ports, utilizing the second 2-pairs of the RJ45. With that addition, the board would be box ready for use as a firewall.

The ethernet is built into the SoC, and there is only one port. Additional ports (likely up to four [4] more) can be easily added via USB3.

Ahh yeah that makes sense, i did wonder if this was an SoC thing. If thats the case like you say adding one on USB3 is the sensible thing to do as it wouldn't make any difference if it was onboard or not.

@Odroid
Did you underclock the A73's for better power consumption/heat characteristics? Or is this the same baseclocks as for the Amlogic datasheet?
Did you try higher clocks with a fan? If so, what more is possible?

I find it weird that the normally "high performance" A73's are clocked lower than the" energy efficient" A53's.
Is the A53 used for a higher single core performance? Or is it for a lower power consumption at low use? Or maybe both?
Do you have the datasheet for the S922X and can you share it with us?
Thank you, but also ... why do you have to announce it 2 months before release? Don't you know how impatient I am.
Greetings, NicoD

What number are you seeing for the clock speed of the A53? The only number I see is 1.8 GHz for the A73s, which is higher than the 1.53 GHz limit of the A53's on the C2.

ODROID-N2 : CPU A73 1.800Ghz / A53 1.896Ghz / DDR4 1.320Ghz

And 1.53Ghz isn't a limit for the C2. I run mine at 1.75Ghz and ram at 1104Mhz for years. Still my fastest 64-bit quad-core. Maybe only for a few days left, the Pine H64 and Orange Pi 3 are on the way. 1.8Ghz should be (very slightly) faster than 1.75Ghz.

The A73 has more execution resources than the A53. I don’t have the details handy, but it is probably wider dispatch, more execution units, possibly lower cycles for certain instructions, out of order execution, more cache, more bandwidth. It ought to be able to do quite a bit more per clock cycle.

Anecdotally, the A72 cores on the Denver have about twice as much throughput as the A57 cores, which in turn seem to have about twice as much throughput as the A53, at the same clock speed.

But also worth noting the A53, A57/72, and A73 are designed by three completely independent teams at ARM, might as well be different companies.

@odroid: I realize that you’re still a couple of months away from actually shipping this little beast, but I would like to know what the roadmap/strategy is for Linux kernel versions. I’m running 4.14.x or so on my HC-1, and for my needs it was a big improvement from 4.9.x. Once you’ve shipped 4.9.x as announced, are there any showstoppers/dependencies that prevent leaping ahead? Can you talk about your intended path?

That is what I also thought. But I think it will be close with all SoC's. All tho I don't know how well the A73 performs.
Here 7-zip small cores vs big cores of the NanoPi M4. Small cores at 1.5Ghz, big cores at 2Ghz.

NanoPi M4 |SBC bench result |CPU Miner |7-zip s/c |7-zip b/c
Armbian bionic http://ix.io/1nLh 10.23kH/s 1335 2005

So here the small cores run at 90% of the big cores if they were the same speed.

Anecdotally, the A72 cores on the Denver have about twice as much throughput as the A57 cores, which in turn seem to have about twice as much throughput as the A53, at the same clock speed.
I know it will perform better, but I don't think it will be 2x. Maybe 20%, but I'm guessing...

You can overclock both to 2GHz per wiki but I assume not all boards are stable
Yes, you can try higher cpu frequencies than the default clock, A73 1.8GHz, also A53 1.896GHz
https://wiki.odroid.com/odroid-n2/appli ... t_cpu_freq

As we put CPU and GPU stress tests with stress-ng and glmark2 (off-screen option),
in case of 1.9GHz, 2 or 3 threads of stress-ng turn stopped as "defunct thread" during the stress test, or reboot in case of some boards. (about 10%)
Even though our test condition is very hard case,
but I can't say it can be guarantee all boards are stable with 1.9GHz (1.908GHz) and 2.0GHz (1.992GHz) with FULL CPU cores working as 100%.

This will depend heavily upon the workload. In some cases it ought to be a lot more than 20%.

Does hardkernel have a recommended alternative to the Smart Power that can do the >7.5 volts needed by this board?

I think you can replace a few resistors on the smart power to make it output 12V. They used it for HC2. Not sure if it's documented though

The old Smart Power can't generate higher than 5.3Volt.
But new Smart Power 2 can do it if you replace one resistor.
We will make a guide soon.

The Y-axis unit is wrong
It must be divided by 1K. ;)

What was the relative performance gain running 1.8 Ghz vs 2.0 Ghz? ;)

We will be very eager to see what we can do with this board. Since I saw reference to PPSSPP on the FB does that mean that the 18.04 build was used to test and if so is it safe to assume that the Xinput issues are not present as they are in the 18.04 build that was supplied for the XU4?

About 10% gain for 2.0GHz compare to 1.8GHz.
You can find a graph, [Sysbench score vs CPU Frequency] at the first post of this thread. ;)
And here is a numeric table of the sysbench graph.

@odroid was so generous to send a lot of development boards to Team CoreELEC developers. We already started working on it and we are confident to have a working image for Odroid N2 soon. I will buy a lot of those boards personally to replace my C2/LePotato's. I'm sure we can get Full HD Netflix with SW decoding working.

I still hope we will see an Odroid C3 with maybe S905X2/2GB which would also be sufficient for a CoreELEC image.
That is excellent news. This is exactly what I would want out of the N2. I was not sure about N2, but now I am little closer to ordering one :D

We've added another benchmark test result for better understanding the S922 multi-core performance on the second post.

I am very happy to read this news. The N2 looks like very good and I hope I will be able to test some of them soon.
Thanks for the job.

There is no interface of PCI-e on ODROID-N2.
From the data that is on the Internet, this processor has support for pci-e. But hardkernel for some reason, they did not want to add slot pci-e.

Without pci-e, this board don't is nothing interesting. :(

Very nice and awesome board.
Everything that I hoped for to be honest !
Can't wait to build my Fedora image for it.
Also I hope amlogic will support drivers with dvb support as they did on their previous socs.
Then we can port our Open Vision project for running enigma2 on these as well. (just get myself another cheap xbox one dvb-c/t tuner)
