eternalWalker Posted May 27, 2016 Posted May 27, 2016 Some sort of hope? http://nanopi.io/nanopi-m3.html http://www.friendlyarm.com/index.php?route=product/product&path=69&product_id=130 Great eW
zador.blood.stained Posted May 27, 2016 Posted May 27, 2016 Some sort of hope? Hope for what? For another board with microUSB connector for power input? (Though it can be powered through GPIO pins too) Or for another SoC with no mainline support in near future (Samsung S5P6818)? I don't see that many common use cases for 8 cores with 1GB RAM, no native SATA or USB 3.0 or at least USB2.0+UAS, especially for its price. 1
eternalWalker Posted May 27, 2016 Author Posted May 27, 2016 Hope for the future && kernel 4 ....and must be cheap and fast And what do you think about this ? -> https://www.parallella.org/ Great @zador.blood.stained ...what you do with your Cubietruck Orange Pi One Paperweight A64 aka Pine64+ Raspberry Pi B ??
zador.blood.stained Posted May 28, 2016 Posted May 28, 2016 More about NanoPi M3 - USB ports are behind USB hub... And what do you think about this ? -> https://www.parallella.org/ Very specific board with high enough price, "Applications" tab on their site tells enough use cases where this price is OK. Unless you need FPGA or RISC co-processor and you know how to work with this stuff, you don't need this board. ...what you do with your Cubietruck Using as headless server: NAS with 2 HDD drives for storing stuff (Samba, rsync, syncthing), headless music server (mpd controlled via IR remote or Android app). Orange Pi One Waiting for Ethernet and USB support in mainline kernel, meanwhile it's useful for testing intermediate Armbian releases. Paperweight A64 aka Pine64+ Waiting for the bright future (at least mainline u-boot with SPL and basic support in mainline kernel). Raspberry Pi B Turn lights on and off with IR remote using connected IR sensor and nRF24L01+ module Display stuff (weather forecast, date&time, new e-mail notifications and some other things) on HD44780-compatible LCD display. 3
wildcat_paris Posted May 28, 2016 Posted May 28, 2016 I have looked at the M3, honestly the CPU/GPU is far too powerful (& maybe overheating) with so limited interface. Better go with T3 version. looking quickly at the M3 SoC datasheet, Samsung has plagued the SoC with the same "Trusted Zone" (firmware) as Ordroid XU4. So, I have ordered a M1 1GB yesterday as a "spare" for the Raspi 2... Well Armbian have some support with the Allwinner H3 SoC => 16 USD + 10 USD
Tido Posted May 28, 2016 Posted May 28, 2016 So, I have ordered a M1 1GB yesterday as a "spare" for the Raspi 2... Well Armbian have some support with the Allwinner H3 SoC => 16 USD + 10 USD MicroUSB power connector !?! Why didn't you go for any other H3 SBC ? 1
wildcat_paris Posted May 28, 2016 Posted May 28, 2016 (edited) MicroUSB power connector !?! Why didn't you go for any other H3 SBC ? RPI has microusb power too I have proper cables (tested). Armbian support... but ok... it is too late, I have ordered. Edited June 24, 2016 by wildcat_paris far too late :(
eternalWalker Posted May 29, 2016 Author Posted May 29, 2016 I think I order the NanoPi M3 . I found a lot of interesting properties . Actually , GPIO is compatible with all other boards (40pin banana, raspi, orange...) . But , there is something interesting to read : http://wiki.friendlyarm.com/wiki/images/8/8b/SEC_S5P6818X_Users_Manual_preliminary_Ver_0.00.pdf SPDIF - TX and RX, LVDS, HDMI and MIPI, ADC (!) & more.... and, and, and... And 45 bucks (with shipping) are 40 Yuros That I can still afford ( for fun ) The T3 would be better, but it costs more than twice M3 And ... this is completely different than the 'banana' or 'orange' (at least for me) Great eternal 1

Well Armbian have some support with the Allwinner H3 SoC => 16 USD + 10 USD Strange. Since Orange Pi PC costs less (15$ + 3.50$) and is faster if you run heavy workloads (since throttling will happen later due to the better voltage regulator there).

I can do DIY to make a good power supply with a step-down mini-board. I am re-learning and testing electronic, even now power electronic like solar panels (or AC) regulator to fill a 12V lead battery, then trying DC/AC inverter (hoping to approach sine wave form), current regulator (I have ACS712 hall effect miniboards) So I am learning, making mistakes, learning, testing...
kometchtech Posted May 30, 2016 Posted May 30, 2016 Octacore "voluntary design (ARM64) you can buy cheaper, so personally hoping for Armbian.
Guest Eric Olson Posted June 7, 2016 Posted June 7, 2016 The NanoPi looks interesting to me as an affordable computer for teaching parallel processing. Has anyone received the NanoPi M3? How does or work? Are there any reviews or benchmark results posted anywhere?
tkaiser Posted June 7, 2016 Posted June 7, 2016 The NanoPi looks interesting to me as an affordable computer for teaching parallel processing. Why do people like all these horrible octa-core designs? If you want an opinion: http://www.cnx-software.com/2016/05/20/35-nanopi-m3-octa-core-64-bit-arm-development-board-is-powered-by-samsung-s5p6818-processor/#comment-526861 'Teaching parallel processing' should also work with a way more affordable Orange Pi One and if I would be interested in aarch64/arm64/ARMv8 (which I'm not that much since my use cases don't benefit from 'twice the bits') then the Pine64 would be my board of choice (due to being a 'real' 64bit board where you can learn to deal with ARM's Trusted Firmware, bringing up the board in aarch64 state and so on -- all that not possible with the Cortex-A53 design we're talking about here -- Nano Pi M3 -- or Raspberry Pi 3 for example that's currently also a 64-bit SoC that can run only in 32-bit mode) 1
ejolson Posted June 8, 2016 Posted June 8, 2016 'Teaching parallel processing' should also work with a way more affordable Orange Pi One.It is definitely possible to introduce parallel processing with a quad core. My thread on the Raspberry Pi forum discusses compiling new versions on gcc with support for the MIT/Intel Cilk parallel programming extensions on ARM devices. The compiler is tested with parallel algorithms for sorting, prime number sieves, fast Fourier transforms, computing fractal basins of attractions for complex Newton methods, numerical quadrature and approximating solutions to high-dimensional systems of ODEs. It is of practical interest how well the implementation of each algorithm scales on physical hardware. Due to constraints of shared memory and I/O very few algorithms scale linearly with the number of cores over a very large range. This leads to an engineering problem that may trade off algorithmic efficiency for parallel scalability to achieve fastest execution times on multi core CPUs. With a quad core CPU the maximum theoretical scaling is four fold, while an eight fold increase is possible with an octo core. Modern compute nodes have 16 to 48 CPU cores and thousands of GPU cores. Thus, while it is possible to consider parallel optimization for a quad core, the problem is more interesting with eight cores. 2
tkaiser Posted June 8, 2016 Posted June 8, 2016 Thus, while it is possible to consider parallel optimization for a quad core, the problem is more interesting with eight cores. Sure, but you should still keep in mind what you're dealing with. The Nano Pi M3 we're talking here about has 8 Cortex-A53 cores but comes with a horribly outdated kernel (see the statement on CNX: "Specifically, this is a Linux-3.4 kernel that looks more like a Linux-2.6.28 platform port that was forward-ported") so be prepared that instead of focusing on the real problems you deal with crazy performance weirdness or memory constraints or something like that all the time (we just went through this with the 3.4.x kernel we used for H3 boards showing a nasty 'kswapd 100% CPU-usage' bug -- switching to a newer kernel variant that has been made available by the SoC vendor solved this specific problem for reasons unknown to us) What about other octa-core boards? Banana Pi M3 (A83T) or the more affordable LinkSprite pcDuino8 Uno (H8 which is the same as A83T but with another chip ID) share the same 'crappy 3.4.x kernel' problem (it's basically the same outdated kernel sources we used for H3 before) and both vendors are clueless like hell regarding software/support. So be prepared to run into the very same problems. Also all these 3 designs are both crap regarding DC-IN (Micro USB -- leading to voltage drops under high load and limiting max current to 1.8A by design) and heat dissipation (you won't be able to let them run full load on all cores since they easily overheat). So in case you improve heat dissipation and prevent throttling these boards will simply power off or freeze due to underpowering. So the next board to check would be ODROID-XU4 where most of the above isn't an issue but where you might ran into the next round of problems (the SoC is AFAIK implemented as big.LITTLE with two clusters of 4 cores each that show pretty different performance behaviour -- good luck analysing the efficiency of algorithms in such a situation. Might be as horrible as when you try this out with the aforementioned boards where all the time throttling will prevent any meaningful performance analysis). 1

I agree that heatsinks with fans are likely required for any parallel algorithm scaling studies. What about other octa-core boards? Banana Pi M3 (A83T) or the more affordable LinkSprite pcDuino8 Uno (H8 which is the same as A83T but with another chip ID)The CPU in the Banana Pi M3 and the pcDuino8 contain v7 cores. The improved floating point/NEON hardware of the v8 cores in the NanoPi M3 are preferable for numerical work. So the next board to check would be ODROID-XU4 where most of the above isn't an issue but where you might ran into the next round of problems (the SoC is AFAIK implemented as big.LITTLE with two clusters of 4 cores each that show pretty different performance behaviour -- good luck analysing the efficiency of algorithms in such a situation.The work stealing algorithms used by the Cilk programming language should balance loads fairly well on the big.LITTLE architecture. At the same time all cores the same is better. At anyrate, maybe someone who has the NanoPi M3 can clarify to what extent the concerns you mention are real problems.
tkaiser Posted June 8, 2016 Posted June 8, 2016 Sorry, can't provide any real experiences since this is such a clear case of 'DO NOT buy'. After playing around with ARMv8/NEON stuff on another board I won't clearly use anything that only provides a shitty Micro USB connector for DC-IN (why? Since it won't work). It's really that simple: Have a look at the bigger sibling that uses the same SoC, the NanoPC-T3: This one comes both with a sane barrel plug for DC-IN and also mounting holes for a supplied huge heatsink. Now think a second about NanoPi M3, have a short laugh and drop the idea. Or ask the FriendlyARM people whether it's possible to limit cpufreq constantly to 400 MHz since then throttling problems might not occur and you also might be able to reliably power the board through a crappy Micro USB connector. Please be aware that we recently tested a boring H3 (quad core Cortex-A7) board that throttled down to as low as 240 MHz with a specific workload and even had to drop CPU cores. While other H3 boards that are even smaller run happily with +1000 MHz and the same workload. So without ordering a sample and testing this out I doubt it's possible to draw any conclusions. Or simply ask the FriendlyARM people. These are nice guys that aren't that clueless as the other vendors mentioned in this thread. 1
kometchtech Posted June 8, 2016 Posted June 8, 2016 I bought the same system configuration NanoPC-T3. Image has been distributed from the FriendlyARM and is distributed in the form of arm7l, in the form of aarch64 is like. And would convey expectations to the other side, but will support the Armbian!
Guest TheRegnirps Posted June 9, 2016 Posted June 9, 2016 I see a lot of comments here about the power supply and the USB connector and adding power with the GPIO pins. The designer, Mr. Yang of Foshan, is way ahead of you. Look at a NanoPi M1, M2, or M3 you will see a 4 pin 0.1" .025 square post header near the 40 pin GPIO header. This has Tx Rx 5V and GND. You can hook it up any way you want, but it was meant for the PSU-ONECOM Developer Adapter. This is a DB9 with RS232 converter plus a barrel jack for the 5V 2A PSU FriendlyARM uses for everything. On a NanoPC T2 or T3 you will see the same 4 pins in a white socket that takes the same connector from the PSU-ONECOM. You can get them at www.andahammer.com which as I write this I see is doing some maintenance. They are probably under "Accessories". You can provide power and get a terminal without using USB, or use it with USB, or with a USB power pack (usually some 18650 LiPo's and a charger and regulator circuit). You probably need some extra if you are driving a 7" or bigger LCD. Way too many PC USB outputs are weak and drop to 4.3V or less under load. P.S. Mr. Yang's QQ2440 and Mini2440 from 2007 were the Raspberry Pi of China. Every student in the country wanted one and they went hundreds of miles by train to reach a shop with stock. College textbooks were published that were exclusively about ARM architecture and programming.
Guest TheRegnirps Posted June 9, 2016 Posted June 9, 2016 I also run across a lot of requests on forums for SATA. Yet I have done extensive surveys of ProAm and OEM users and exactly none of them want SATA. Any that do need big storage say they will use USB drives. If they need some other device, they sat SDIO is more than good enough. So I am very interested in what one would use the SATA drives for. I know DIY set top box is a big deal inside China, which is the reason for IR on all these boards, but I never see any enthusiasm for it in the States or EU. Are people thinking home server? A 1GHz Cortex A8 aught to handle that and you never need a heatsink.
wildcat_paris Posted June 9, 2016 Posted June 9, 2016 Look at a NanoPi M1, M2, or M3 you will see a 4 pin 0.1" .025 square post header near the 40 pin GPIO header. This has Tx Rx 5V and GND.

You can hook it up any way you want Thx for adding this information! It's important to know that this header can be used on any NanoPi to provide stable DC-IN. I just missed this information from looking at FriendlyARM's wiki (maybe I were blind or it's just missing?). So powering NanoPi M3 isn't an issue using this connector but I still have doubts regarding thermal issues since mounting holes for a heatsink are present on NanoPC-T3 and the heatsink used there is rather huge. Do you have any information regarding thermal 'power' of this octa-core A53 design? I didn't find anything so all my assumptions rely on experiences with other A53 SoCs/boards. 1
wildcat_paris Posted June 9, 2016 Posted June 9, 2016 I just missed this information from looking at FriendlyARM's wiki (maybe I were blind or it's just missing?). My guess the wiki needs to be more clear. Maybe a section : "How to power the board?" http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M1#Layout in the note, you need to find: "VDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB’s the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.6V" because it is not obvious, with the Odroid-XU4, you cannot power the board with the UART plug as it is 1.8V VCC
kometchtech Posted June 9, 2016 Posted June 9, 2016 NanoPC-T3 heatsink with photo uploads. Parameter to that I was reading about the temperature, it is not. 1
tkaiser Posted June 9, 2016 Posted June 9, 2016 "VDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB’s the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.6V" That's written there only for the M1 (H3, no PMIC!), the Samsung based M2/M3 might be totally different (they have an X-Powers/Allwinner PMIC) so information available for NanoPi M1 might be totally misleading when it's about M2/M3. And since we're talking here about something that might fry your board such assumptions might mean 'game over'. So unless this is outlined in M3 wiki entry I wouldn't rely on any information for totally different hardware that just shares form factor and partially the name (same problem with the various totally incompatible Banana Pis for example) @kometchtech: Thx for the image. This should illustrate what to expect with NanoPi M3 without or with small/laughable adhesive heatsink 1
Guest TheRegnirps Posted June 9, 2016 Posted June 9, 2016 The blue adhesive heatsink does OK on the M2. I have not been able to try on the M3. M3 has an AXP228 PMU and I don't know how it is being used yet but should keep it from toasting itself. The big heat sink on the T2/T3 is legacy from the T1 with used Samsung Exynos 4412 before Samsung suddenly EOL'd it and switched to these third party relabeled chips, 4418 and 6818. The big sink might be overkill. Needs some testing. The little blue one will get plenty hot and also dumps a reasonable amount of heat. I have a big pile of the little fans from Dell laptops I got for about $1 each from someone who didn't know they sell for more like $22. Although heat sinks and fans seem really in-congruent on ARMs to me, if it was silent I wouldn't mind. After all, my Chromebook can cook my lap! ARMWorks is back up. They were upgrading PHP. I will try this setup on an M3. https://andahammer.com/index.php?route=product/product&path=67&product_id=109 I think should not include the M2 and enclosure in all the pictures. Someone is bound to get the wrong idea. BTW, holiday in China till next week. (June 14 before everyone gets back I'd bet). Dragon Boat festival and Leechee season in Guangdong. Yum! And ARMWorks is sold out and waiting for a shipment. Check the best secret on the site, the X710 LCD which is sold near cost to help build a user community. https://andahammer.com/index.php?route=product/product&path=63&product_id=133 FriendlyARM LCDs have always been a strong point. This is the lowest cost 7" they make and the killer is that unlike nearly all 7" which are 800x480, this is 1024x600 and looks fantastic! A Debian desktop has a very noticable difference compared to 800x480. Don't tell anyone. It will kill sales of the other displays (except the Rough Service and the flanged bezel ones for fitting a cutout).
