    Lion Wang reacted to Larry Bank in Banana Pi Zero   
    I just received my BPI-M2 Zero board and put it through its paces. Seems to perform similar to other H2+ boards. I added a Pin->GPIO map to my SPI_LCD and ArmbianIO projects (
    1) The SPI driver has that same odd issue where it occasionally spits out errors and runs a little slower than it should. 
    2) It doesn't come with an IPX antenna, but you need to add one to use wifi unless you're sitting on top of your access point.
    3) A small passive heat sink seems to be plenty when running the mainline (4.1x) kernel.
    4) The default HDMI out resolution is 1920x1080p@60fps. This causes a "jumpy" display on my monitor. Switching to 1280x720 fixed it. I've seen this on other AllWinner H2/H3 boards, so it's probably something strange with the mainline kernel hdmi code.
    Overall I'm happy with the board.  It would be nice to use the bluetooth. Does anyone know how to enable it?

    BTW, banana pi zero and nano pi air makes a perfect board for using OV5640 sensor, so i would like to ask @Robert LabTeam if you are going to share your work on the OV5640 to be able to reach 60 fps or 90 fps, will you?

    The key point is CSI camera support without extension board, the missing point is no eMMC and tiny embedded RTC module.

    if the costs are rising to fast - how about installing a standard-eMMC socket like on the ODROID C2 or inside the Pinebook?
    I think this would cost only a few cents?
    For me that would be fine - then while I upgraded my Pinebook to 32GB eMMC I could use the old 16Gb eMMC on my ODROID C2
    AND if the market will supply faster/bigger eMMC modules I can swap out the slower/smaller against a faster/bigger one

    Right, my comment on eMMC is purely about reducing/removing interconnects, the primary failure point in most systems.  Speed is secondary in such embedded systems.  I would ideally use the SD card only for data storage, for instance data logging/etc.

    I think nobody has a complete "perfect" product....neither "Orange Pi" nor "Banana Pi" nor "Nano Pi" nor "Raspberry Pi".
    Every product has some details that could be better (lower heat, better documentation, better linux-images, better cases, less binary blobs).
    So I got some of every sort
    But - I personally - like the wiki from FriendlyElec/FriendlyARM at

    Most - NOT ALL - pages does include very interesting and valuable informations for me (PinOuts and HowTos, FAQ).
    OK some should be more actual - but there are many pages for many diffrent models and if ne page hasnt the information then I could find mostly the information at a page of a other model. 
    The downside - their forum seems mostly supported from users to users. No technican seem to take a look here on a daily basis

    @Lion Wang SinoVoip's gitbooks has to be reviewed. Technical information is not consistent and English is not good enough, it has to be fixed urgently. Over the last years I have been seeing many Chinese companies doing good products or at least pursuing to build good products but failing on how to communicate and support customers, think about it. Never forget that customers don't care about how hard is to build a new product or how insane is to run a business, they only care about how good the product is.
    @Tido gave a good suggestion... before releasing any new product and during the entire product lifespan do short technical / writing meetings with your technical team to consolidate knowledge.
    The entire problem here seems to be about communication, as always. Most of Chinese companies have good engineers that doesn't even speak or write in English. If it is the case, hire someone that could help you to fulfil this gap, as soon as possible.
    @TonyMac32, @chwe thank you for focusing on the real problems, not at person level discussions. In just a few questions I think you got the answers you were looking for. That is a good start point.
    @tkaiser I would like to suggest you to just 'stop' buddy, please.
    Let's give the last chance to SinoVoip understand, change, react and SOLVE the main issues. Everything said here is applicable for any hardware supplier.

    Indeed you do, however it does not have "CON4" anywhere on the board silkscreen that I see, and being a 2x2 header alignment is still a bit of a question, especially when Pin1 is marked to be on the right-hand side, which is non-conventional compared to the rest of the board.  Not saying anything is inherently wrong, the schematic is there, is labelled, but I for one, a senior electrical engineer, did not notice it, instead seeing an unlabelled 2x2 on the physical device.  This should be on your page explicitly labelled, and probably a silkscreen adjustment made.
    Now, were it a 2x3 with 2 of those pins being a V_in....  Now that would certainly be useful and meet the approval of many.  Not to mention making orientation a non-issue as it would then be non-ambiguous.  ;-)
    Do the various test points exist in hardware, such as the "TV-out" (TP8?)?  If not they need removed, simply because you are referring to the schematic as an ultimate resource (as it should be)  That said, TV-out is a Pi Zero feature...
    If you are open to a feedback, I would say a good variant would be one of these without wifi, but instead with the additional USB's available via header, a position for a barrel jack or direct-solder power input, and an eMMC.

    Nice to get a fast response. But when you've ethernet there, this should be on your schematics! and described somewhere.  Most people would expect that the connector might be for powering (or maybe the USB otg). And to improve things, make sure that this information is not only visible here in the armbian forum.  It should also be in your documentation for this board.

    Maybe not for your use cases but for others. Not everyone has the same needs... I see use cases where size and wifi matters... Since OPi0 has heat issues,  and both other cheap small boards (opi0 and nanopi) have the annoying XR819 wifi.
    don't start this again...  Thomas and you will fight on a personal level again, and @Tido will close the thread again...
    Doesn't make sense... If they have an interesting board, I'm sure people from the Armbian community will work on this board (maybe not Thomas but others.. ) And as @@lex said... Edit: Getting basic armbian support for this board should not be that much work. Starting with a similar board (1.1V/1.3 V regulation) add wifi and configuration of fex for the pinheader and you'll have a basic armbian image for this board. 
    I appreciate this, so let's start with the 4pin connector from my last post.

    @tkaiser and @Lion Wang it is time to put an end point on this "fight".
    In my option, things are getting too aggressive and boring from both sides and it is not good for both the Armbian community and SinoVoip business.
    @Lion Wang the community & customers are not satisfied with the information you are providing about your products. As CEO you have to listen and act as soon as possible to correct what is wrong.
    @tkaiser you are essential for Armbian community, but it has been useless to read your posts about SinoVoip.
    My suggestion is to give the last official chance for SinoVoip with Armbian community. I suggest to port Armbian to BPI ZERO and during the porting process both sides tell everything about what is not going right or hasn't been done right. Documentation is not good? SinoVoip will fix it. We need some detailed information about the hardware? SinoVoip will provide it... and so on.
    Let's do it, guys?
    We all want to build an ecosystem between hardware and software and a friendly community.

    I don't remember anyone linking the mainline DT for this board, so here we go:
    It's interesting to see a CPU operating points table there (so DVFS should work already), looks like Ethernet (with DSA), USB and basic peripheral interfaces (I2C, CIR, I2S, PWM, GPIO, ...) should be supported too, but don't see anything that would represent SATA or PCIe yet.

    It is good to know that the R2 it is being taken seriously.  This machine has important things and, although there are very good alternatives, it has a market place.
    I have been sending maybe 100 times by now an 825 megabytes ubuntu iso file from one R2 to another and between an R2 and a Mac Mini machine, testing different types of configurations (in the while I am creating the system I will use the R2 for).
    Here there have some numbers that could be useful:
    (AES 256 bit):
    without /dev/crypto
    100% CPU max
    - real 0m53.189s
    - user 0m44.210s
    - sys  0m8.030s
    with /dev/crypto
    75% CPU max
    - real 0m27.015s
    - user 0m2.290s
    - sys  0m17.750s
    Checking at this test alone, it is clear that with the cryptodev driver active (and with the right openssl compiled for it), the machine it is faster processing.  And then it is the top 100% capacity when using only the CPU ... I was trying to figure how to test that remaining 25% ... so, I made a multithread program that received the data (running in a R2), and executed 4 parallel sets of openssl+sending data from the other R2.
    The "general "throughput" for all the "bundle" gives around 45.8 MB/s.  This is much higher than the around 17 MB/s I can have with only one similar session.
    The issue here is that the final speed can't be calculated only taking into consideration the crypto engine.  A final test would need software designed for this, because when I cypher with openssl and then send the file on ethernet, I need to "write" the file to disk and to re-read it, and the DISK is a key factor on the overall transmission speed.  An extra write is really heavy here.
    So, if I like to see a wonderful speed without sacrificing the machine, the disk must speed up.  The final numbers for secure transmission of data must involve all the key factors : CRYPTO+DISK+NET+CPU.
    But ... in general, I think it is good enough for my purposes.  When I have a better software platform to test all together (without punishing any of the factors), I will come to show my numbers.

    A38X ClearFog
    I think I understand now this board.
    - It is not an integrated board, but a "carrier" based one.  You purchase the carrier board and the SOM (System on Module) to make it to works as you expect.
    It uses only one line for mSATA interface, the same as the R2.  Then, why the difference in speed?
    It is necessary to add a mSATA to SATA adaptor to connect standard SATA drives, or to use mSATA drives.  And uBoot must be modified to allow the PCIe slot to work as mSATA.
    - SolidRun Armada SOM A388 with eMMC : $69
    - With ClearFog Base Carrier $129
    - With ClearFog Pro Carrier $189
    HummingBoard Edge
    Similar scenario than ClearFog (using SOM).
    - Only has 1 ethernet
    - Quad 1 GHz NXP i.MX6 version 2GB RAM and 8GB eMMC: $191
    - Needs M.2 to SATA adapter
    - No USB 3.0 (only 2.0)
    For a multi-ethernet scenario with storage, the HummingBoard is limited by the lack of native multiple RJ45 and USB 2.0 (where the second ethernet could be attached).
    When only needing two ethernet, the ClearFog with Base Carrier seems to be enough.  Cost is around 50% higher than the R2.  And the Pro around 100% higher.
    ROCK64 ... not yet available for purchase (ships until November 3 if purchased in October 16 - Pine has their history on delays)
    - $60.89 without shipping ( 2GB version + 16 GB eMMC + USB-SATA cable ) ~ still lacks a secondary ethernet.
    - It only has one USB3 port, so the bandwidth must be shared between SATA and any secondary ethernet.
    - $49 in amazon
    - Dual Core
    - Three Gigabit Ethernet ports (1 WAN, 2 LAN)
    - Independent SATA interface with its own Power Supply
    - Proper 12V barrel power connector
    - Mini PCIe
    - Has the place to add the eMMC but it seems must be soldered there
    R2 still has a place in its price/availability/performance ratio.
    If there is an ExpressoBin with eMMC included, Quad Core and 2GB, maybe it could cost around $80.  In that case, would be a better option than the R2.
    The ROCK64 lacks interfaces to provide good bandwidth when the multi-ethernet scenario is included.
    It is not possible to have HummingBoard with multiple Gigabit Ethernet connections.
    The Armada SOM is Dual core ... could be possible to use the HummingBoard SOM with the ClearFog carrier?
    The main important elements are to determine if an improvement in the software can work the problems detected with the R2 for the full performance capacity.
    In my particular case, although performance has some importance, it is not the main driver to choose one or another product.  The processing unit is more important (hence 4 cores would be better than 2), together with the integrated eMMC (I can't deal with soldering these tiny things) and the availability for connecting devices.
    Today all them are not so perfect (taking all factors into consideration) options.  I am sure than in 6 months this will be a completely different world.

    BPI-R2 in Armbian forun has been as a thunderstorm.  It is sad things are not in good terms, as the machine looks nice and I am sure that it could have a nice horizon with Armbian.
    I am working a security device on these devices (an appliance containing a small network), and by now, this is the best hardware option available:  eMMc, many gigabit ethernet ports (two different networks and, in the future, different VPNs in one of them), USB 3, 2 GB RAM, SATA support, 12V power, GPIO, etc... for less than $100.
    It is clear that the machine is a new one and it has some problems, but it is possible to deal with them.
    - Wrong number in the partition configuration when trying to boot from eMMc fix:(
    - Have no idea how to turn on a connected FAN in the FAN socket, although the secondary SATA has 5v and 12v and there are the GPIO pins.
    - Very long time pressing the power button for the machine to start - optional fix (soldering): (
    - Two SATA interfaces in the same SoC line (as a workaround, use a SATA and a USB disk, not two SATA)
    - The software distribution from BPI is a mix of things ... there are even parts for Raspberry that I am sure have no relationship with the R2.  Here the grease must be cleaned.
    There are other details, but I really don't care on them.  The machine form factor it is not really to make an entertainment center, and the only I need is to be able to check the console with the debug pins or to connect through the network.
    If BPI and MTK could create a server distribution and not the full Mate based Ubuntu, would be very useful.  And there is a LEDE available also, although it is a different point of view.
    P.S. I am waiting for some machines to make a deeper test.  In this moment I have an OPi Zero in the entrance point, so I can't check the total bandwidth ... later I will provide more data, including my own disk throughput tests.

    Sorry to say this: No, it has the same problem as the Lamobo-R1: The WAN and LAN ports are bridged until the network is initialized; this allows attackers to reach inside your LAN and spread spam-bots or other bot-nets in your LAN if you use the R1 or R2 as a firewall+router.
    Purchasing the R1 was a mistake.
    I've spent so much time trying to get it to do at least something, but no luck.
    It's in a different location from where I am located right now; packed down in a box somewhere.
    -Perhaps I can use the power supply for something, but that's all. I've given up on it.

    $ 15.00 ?
    That's a good price for what the board offers, mini HDMI, CSI port, 512 MB and Wifi&Bluetooth. Personally i would add a 8 GB eMMC and try to keep the price below $ 20.00. Once you boot from eMMC you will never want to boot from SD card again.
    BTW, Have you considered Banana Pi M2M? no HDMI but there is a MIPI DSI port to connect LCD panel, and i can say the 5" LCD is the best LCD i have tested so far, unfortunately i have damaged the LCD some how while porting it to M64. They are short on supply another sample but Nora Lee is kindly sending me another one when they are ready so i can finish all the tests, i have not tested it to the exhaustion nor did any extensive testing but there is no problem with heat and Wifi&BT works as expected and the board has been a nice surprise.

    Is the NEO2 supported by armbian ? It has a H5 cpu and I do not see one page for it on the armbian download page.
    I agree that with such hardware, I will not get better performance than my bananapro.
    Nevertheless, I am not that hungry with performances.
    Here is what I would like to do : plug a usb hub on the type A usb receptacle of the NEO /NEO2.
    Then, plug two or three 2.5" usb disks on the hub.
    The hub (yepkit/ykush see link in earlier post) is self powered with a 5V/3A power supply and can support three 2.5" disks in the same time. Disks are wd blue, assumed to have low consumption.
    I tested this yesterday, all disks runs well.
    This installation is designed to backup the bananapro installation. I just want to pay attention that the usb to sata link is able to pass hdparm commands like hdparm -B, hdparm -y so that I can put disks
    in standby mode, for as a backup I do not need them to be running all the time.

    Right - we have a dialogue with the vendor, we know why some people are unhappy and we know what's needed to assess the board. There's a language barrier and there are elements of documentation that have changed or are incomplete. Not every tiny thing is clear but certainly enough is clear to make a start. The vendor wants to help, they're here right now trying to. Let's stop going on about the past, things change - if they don't then I'd like an apology from Thomas for killing my grandfather in world war 2.

    I've got this board, I'll answer questions to the best of my ability. It's running, it's stable, it's definitely more achievable than some boards that have been bought up in the past for Armbian.
    The R2 uses a 12v supply with a 2.1 x 5.5 mm connector - at least a 2 amp supply is needed.  The first production batch is board revision v1.1. It has two upright SATA ports, a 4 pin power connector to the one side of the SATA ports, a 2 pin power connector between the SATA ports and a molex branded clip to hold full length mPCIe cards - mounting holes are present for half length cards - standard risers of 2mm height, 2mm width should be used for half length cards. This is what the v1.1 of the board looks like :

    The WIFI/BT chip is the MT6625L - it may be the case that they used a different chip in a previous revision - I don't know, but the manual says MT6625L - the chip says MT6625L. I've searched high and low on google - I can't find AP6212 in reference to this board. If you're upset by this then please elaborate because I might be missing something obvious. The 6 pin connector for the battery appears to be a micro JST SH connector with a 1mm pin spacing. I have such plugs and they fit, I will ask the vendor for confirmation. In the meantime, here is a page where the connector I have can be purchased ( Here is a link to the current logical schematic for this board - Here is a link to the current physical layout of the board - Here is a link to the datasheet for the MT7623N - If you need to know the ID of certain chips, please ask me and I'll tell you what's written on the chips I have. Here is a link to the github of the R2-BSP kernel. U-boot sources are also in this repository - Here are some patchwork links to various developers currently working on drivers/patches for Mediatek chips :
    (This list may not be exhaustive) Here is a link to the BPI-R2 section of the Banana Pi forum - The board is incapable of time travel, opening portals to other dimensions or fixing failed marriages. Hopefully this isn't a problem.
