quick review Banana Pi M3

Recommended Posts

My specific use case is a network monitoring device. Basically i want to send all network traffic (internal as well as external) to the device and apply some monitoring to it. That's why it needs a high performant network interface, and some decent processing power. Ive tested it on the rpi3, and while it works fine for very small networks, I would love to improve the performance a little bit.

 

Well, still missing some bits of information to give a recommendation (no idea what's the bottleneck). At least when this should be some sort of sniffing a 2nd network interface and decent processing power would be great and then it's already time to think about x86 based solution (BTW: That's one of the advantages of Apple MacBooks like the ones i use: By simply plugging in one or two $25 devices one gets one or two more GbE NICs -- connected through PCIe and not Thunderbolt -- that can be used for real-time sniffing by intercepting all traffic on a wire)

Hello, friends!

I will share my experience. The seller sent me a broken banana pi. Inductance is damaged on the board. Where I noticed the Close-up closeup the Close-up closeup 2  Council work, but on the net there were errors. I did not want to send it, because in Russia the cargo is a lottery. I offered to return a small part of the money to me. I do not think that this breakdown is serious. I soldered the inductance, I soldered the power plug, he behaved badly.  
But the seller refused to return a small part of the money. I do not want to complain, but to warn people that the seller is not loyal. Now my board is  working I'm sorry, I filled the board with the composition , but I do not know where to get a good operating system. In those that are available on the site, the  banana pi  does not work. What will the community tell me?

Why are not Enthusiasts engaged in Armbian for this board?

Today, including the board, I noticed that the kernel is not always loaded exactly.  I'm using the debian 8 kernel 3.4.39, desktop mate.  Once the board loads it can work well, work clearly, without errors, all interfaces and devices will be available.  But the board can be loaded incorrectly.  There will always be errors, not all interfaces and devices will work.  There is a serious problem, there is no support for the UART kernel.  I want to communicate with the community, I want to learn how to enable the UART kernel in the bootloader?

Today the seller returned the money for the damaged board. I am grateful to him.

SATA

 

There is no SATA on this board. It's important to not spread wrong rumours. Banana Pi M3 just like Orange Pi Plus simply uses the most crappy USB2-to-SATA bridge on earth:

What's the purpose of providing an Armbian image for this board? Encouraging users to buy it since 'Armbian support is there'? Why not better spending the time on fixing the forum (broken on iOS at least, a huge fixed Armbian logo on top of each thread prevents reading thread titles and top post)

 

Are you aware that SinoVoip produced a new M3 batch now using an incompatible eMMC, needing some fancy instructions to get their own images working?

That those few who had bad luck buying this board can perhaps use it?

Well, I am not planning to provide any support for it. I saw patches ... A83T is a first big/little with a mainline support. I just needed to see how it works.

Huh? The A80 predecessor was big.LITTLE but this here is just little.LITTLE (just like with Vim2 or NanoPi M3 or NanoPi Fire3) and all these other boards combining two clusters made of slow CPU cores have pretty decent kernel support. Or are you talking about uninteresting EOLed Allwinner SoCs only?

 

I already though about a detection for those poor little.LITTLE designs since 'armbianmonitor -m' output is highly misleading sometimes showing different clockspeeds for the two clusters that clock in reality always identical.

Yes :) A80 was prior to this, but support was also never mainlined. It is probably getting support with this batch ...  A80 is even bigger exotics and there are just little boards out there.

Sure, 'the Allwinner syndrome'. Once the SoC is EOL and can not be purchased any more the brave souls over at linux-sunxi finished mainline kernel support. Situation 3-4 years ago was different but today I really have no clue why to waste a single second on anything Allwinner that is not also cheap as hell (talking about the small OPi and NanoPi boards) or makes good use of Allwinner's battery support (PineBook, Olimex' Teres, Olimex Lime/Lime2 boards that use the battery to provide full 'UPS functionality' since also powering USB and SATA devices via step up converters)

 

Banana Pi M3 with its outdated 32-bit Cortex-A7 little cores and the totally unsupported PowerVR GPU is even more expensive than faster little.LITTLE designs like NanoPi Fire3 or even true big.LITTLE designs like ODROID XU4/HC1/HC2 (the latter also with an USB-to-SATA bridge but USB3 based and more than 25 times faster than the crappy GL830 on the M3).

I have to admit that we should freeze/remove BPi M3 images and also freeze threads of it.

BUT, mention equivalent SBCs like the ones TK listed.

 

Who supports this ?

Me not since I hate censorship (freezing/manipulating threads).

 

BPi M3 is not listed here https://www.armbian.com/download/?tx_maker=sinovoip so far and if it remains like this I'm fine with it. We all know that SinoVoip has a great history of false advertising (and misleading announcements) so I would prefer if Igor replaces in such 'announcements' like this all details with a simple link to this forum. So users thinking about buying this board have a way to inform themselves without any censorship involved (the 'sinovoip team bpi' monkey over in their forum reportedly censored over and over again)

 

Wrt 'equivalent SBCs' IMO there exists no such thing. It's always about use cases and that's what potential buyers have to think about first. But as far as I noticed the average BPi M3 buyer got fooled by the impression he gets 'native SATA' on the M3 just like on the older Bananas and that people think '8 cores' make up for great computing power (which is BS especially on a board with a broken thermal design and no way to attach a suitable heatsink).
