A80-OLinuXino OSHW 8-core Linux computer development begins


Email banner-ch

Allwinner is about to release soon (end of this month hopefully) datasheet and info about their new 8-core monster processor with 4x Cortex-A15 + 4x Cortex-A7 and here we go and start preparing what to include in the new A80-OLinuXino.

We would love to hear your feedback and recommendation what do you think is important as value and “to have” on board, here are the major features (taken from Allwinner site) :

  • DDR3  standard 2GB, optional 4GB
  • Gigabit Ethernet
  • optional NAND Flash 4GB
  • SD cards x4 possible
  • USB-OTG 3.0
  • USB hosts x2 2.0
  • MIPI camera interface
  • real ADCs x2
  • PWM
  • UART x7
  • I2C x7
  • SPI x4
  • I2S
  • LCD

Unfortunately A80 have no audio on chip so external codec is necessary if you want to have Audio connector how important is this if we already have audio on the HDMI connector?

If we go in to LIME form factor route we have to look just for the bare minimum of connectors due to the space limitation, if we go in max features direction the board will become big and expensive.

Let’s the wishes begin 🙂

    If you do a LIME board with the A80 and you really really want a lot of interfaces, you could do targeted versions. For example the A/V one has HDMI and audio codec with S/PDIF output etc. and the network compute node one has multiple network interfaces and so on.

    You could also go the modular way in which you have the base LIME form-factor board which contains the bare minimum and you have a couple extra daughtercards which plug into the GPIO connectors and offer extra interfaces (similar to Arduino shields or BeagleBone capes).

    Having said all that, I’m afraid A80 is really meant for applications and not for automation or DIY and hacking — that is, for phones and tablets and not so much for IoT nodes, home automation, CNC controllers and the like.

      with 8 cores this is more close to pocket PC with desktop experience USB keyboard/mouse and HDMI display, or for intelligent IP cameras, running opencv, doing extensive computing, rather than to be used as dummy XBMC player which even $35 single core arm11 Raspberry PI could do , so I still doubt if to put expensive audio codec and waste space with audio connectors

    Please keep it tinker-friendly. By that, I mean keep options open for non-obvious use (e.g. having audio on HDMI implies a connection to HDMI device and not, for example, LCD and battery-operated form factor).

    I personally would love to make my own dual-screen dual-OS “laptop” for example so this would be a good fit.

        It would be really interesting to know why a multi-ethernet option cannot be offered, and whether a add-on module might be looked at to provide this option. I note the availability of the UEXT modules, but need a little more info about implementing a working prototype. To have a module with multiple ethernet ports AND a switch chip which I could use to build a firewall router would be a boon!

        Sure if you have a HDMI monitor WITH speakers, then HDMI audio is all you need. The problems are – DVI monitors used via HDMI, LCD screens, and headphones. And audio is used for more than just music. With an octo core and lots of RAM, you might want to play high end Android games on your LCD. So some non HDMI audio will be needed for lots of uses of such a high end board.

        For me my use case is a portable desk top replacement, but not quite a laptop. Something small I can use at home, plugged into my DVI monitor, and non HDMI speakers, then carry to various clients offices and plug into their network / keyboard / mouse / what ever random monitors they might supply. Probably hooked up to a LCD touch screen when travelling between the two, and non HDMI headphones.

        I would also have a use case of making virtual world servers out of them. Maybe even combining the two use cases into a virtual world server / client combo.

        So, my wish list –

        4GB RAM
        micro SD card slot, four would be nice, but at least two.
        Ethernet, gigabit would be nice, but not mandatory.
        WiFi
        2 USB + 1 USB OTG
        Battery connector and charger.
        HDMI output, suitable for pluging into ordinary DVI monitors via the usual style of adaptor cable.
        Headphone output, only needs to be stereo.
        LCD + touch screen connector (resistive actually, I’m one of the few that prefers them over capacitive), really high res OLED if possible.
        UEXT ports
        RTC with super capacitor backup.

        I really don’t understand why all of your computer boards that include an RTC fail to include any sort of backup power supply, only the UEXT one includes a battery. On top of that. I don’t understand why the industry in general only uses batteries, I was putting super caps in hardware designs decades ago, these days it’s all you would need to keep an RTC running.

        If you go the HDMI-only route, there are HDMI -> DVI adapters (originally by ATI, now everyone builds them) that also “deliver audio to the monitor/TV”. How that works is they intercept the I2C traffic from the monitor (containing monitor capabilities info) and add that they support audio to packages so gotten, then pass them on to the computer. So as you can see it should be easy to just have the driver enable audio out in the first place (if the DVI monitor / TV has audio, and if it actually uses the speakers that are in the chassis 😛 – some don’t) and indeed Linux has an option to do so.

        Unfortunately, HDMI audio is digital so it’s not simple to build an adapter that converts it to a normal 3.5mm analog audio socket.

        Even when not having analog audio, audio is not bandwidth hungry, so one can just add an audio dongle on USB (USB speakers do that anyway) and still have 90% of the USB bandwidth available. Or use a PWM or DAC.

        (an audio DAC chip is about EUR 3. The amplifier is mainly one OPV, about EUR 1 per item, on the other hand for about EUR 4 you can get USB speakers on eBay)

        The only things that are so bandwidth sensitive that they must be onboard are graphics and the RAM connection.

        But having a graphics part (PowerVR) that passes hundreds of different C structs around via shared memory at high speed (which probably has about as many buffer overflows left, both on-chip and in the binary driver) is bad. But what can you do…

        Why I need more audio connectors?
        I want to use the computer for VOIP, so I need microphone in and headphone out. I want to play quality sound. So I need S/PDIF. My monitor is switched off when I don’t compute and the sound quality is just terrible.

        What I need else?
        Fast flash of at least 8GB for the system.

        Everything else I don’t care much.

    Hmm… Gigabit? Sure? The specs sheet says EMAC not GMAC.
    Then, no SATA, no analog video, no analog audio, PowerVR instead of MALI, that stupid big.LITTLE design. Well, if you want an Android gaming console/set-top-box or tablet that may be the right SoC but as a development board? Not really.

    The only thing that sounds reasonable to me would be an A80-SOM that’s pin-compatible to the A20-SOM.

    If you want to make a better LIME: A20 with 32bit memory, gigabit switch chip instead of a single phy, a case with a place for a small LiPo and a HD/SSD, more LEDs, a beeper, internal sdcard instead of NAND. Oh, and regular .1-mil headers (with through hole pins, not smd)!

    Audio In/Out is nice.

    SATA would be too, but from what I see this will not happen – so you just saved some space on the board 🙂

    It is about time to think for some boards that will be used as nodes for processing, network and etc. => More Ethernet ports and SATA (an A20 design here with say at least 2 gigabit ports would be great for router, NAS, personal cloud, many computing nodes interconnected and etc.)

    Before anyone asks, my operating system of choice is Plan 9, a wonderful distributed operating system crippled by the absence of simple and powerful platforms capable of supporting all its features (as well as a large community of sophisticated developers).

    One thing to consider: greatest part of this SoC is based around Video, 3D graphic. I hope that AllWinner will release Open Source drivers, or at least specifications, which enable use of their hardware in open-source manners.
    I have to fight with 14 years old system, keep Socket 370, only because one library prevents me to upgrade to fx Core2Duo.
    It would be amazing to use OpenCl on this SoC.

    As others have pointed out above, the A80 will take Olimex more strongly into the “small personal computer” camp than has been the case so far. Traditional embedded uses will no doubt continue to appear and expand (for example embedded image processing will be extremely happy with all those cores), but an A80-OLinuXino could also become an ordinary personal computer for many people.

    This makes me wonder whether a jack-of-all-trades design is the right way forward for the A80-OLinuXino. Already the A10/A20-OLinuXino boards dedicate much of their valuable board area for lots of 0.05″ pitch expansion connectors that will never be used by those employing their boards as small Internet servers or as media interfaces for TV say. They’re very useful (of course) for those who are using the GPIOs for traditional embedded interfacing, but this highlights the problem — a jack-of-all-trades design will never be optimum for any given use case, and there are at least two major use cases that differ strongly in their requirements: embedded interfacing, and small personal computer or Internet server.

    It’s worth keeping in mind this distinction and the conflict between differing use case requirements, because it’s important to understand which market is being served. If both markets are being served, then perhaps two different designs should be employed so that their appeal is stronger in each category?

    There is little doubt in my mind that a large proportion of A80-OLinuXino users who intend to run their boards as personal Internet servers or as small personal computers would prefer to trade off most of the GPIO expansion board area found on a LIME in exchange for more memory, say. This is not the only relevant trade-off, just an example that highlights one important requirement common to both servers and personal computers, namely ample memory.

    In summary, I suggest that you think hard about the possibility of offering two different designs for your A80-OLinuXino family, targetting these two very different umbrella use cases.

    (I’m interested in both application areas, but since gigabit Ethenet and a large number of cores is a new combination for OLinuXino and it would let us build excellent little Internet servers, I would like to see it well endowed with memory.)

    Olimex wrote that A80 does not have native (analogue) audio, just I2S, and that adding an expensive codec doesn’t seem like a good idea. This is probably a reasonable argument given that analogue audio users could just add an external USB audio device, and most important for low cost, it avoids the board requiring low noise analogue circuitry. I tend to agree, but there is an alternative available.

    Since audio data is already present on I2S, why not leave it in the digital domain and offer it as coaxial or optical S/PDIF? That would make best use of the A80 without requiring a quality codec for decoding into analogue, and it avoids the need for low noise circuitry, power or shielding on a low-cost board. Audio bufs will appreciate the better quality of a digital audio connection too.

    I tend to prefer “horses for courses” to keep costs down and to avoid paying for what one doesn’t use, so perhaps a small add-on board interfacing to the I2S signals on an A80-OLinuXino header would be in order. It could offer both coaxial and optical/Toslink presentations in parallel since bit-wise they’re identical.

    This would provide the quality audio interconnect for non-HDMI applications which A80-OLinuXino will otherwise lack, will add a little money to Olimex coffers, won’t take up any OLinuXino board area, and would avoid the low-noise analogue design issues and costs mentioned earlier.

    What would I actually *use* a board like this for?
    Well, for me it’s too powerful (and maybe with a high power consumption / heat output? anyone know) for embedded use.
    It would make a handy “home console” part DVR, part video phone, environmental monitor. Though this sort of thing is converging with more traditional PC applications.

    With all that power, I’d like to see a couple of USB (USB 3?) hubs on the board but with careful board layout so that all the USB ports are accessible without obscuring any other features or connectors. May be a long, thin board instead of a square-ish one? It would be helpful to have an RTC + battery backup on the board as well. It would be nice if some of the SPI could be run to onboard peripherals, such as digital I-O. Finally, it might be wise to have a CPU temperature monitor and some voltage monitors on the board, too.

    So far as add-ons go: how about a daughter board that brings all the peripherals out to just one side, so we can easily encase the system without having a Raspberry Pi situation where there are sockets and connectors on all sides.

    Now that you are asking for sound, and it’s my area, I would like to make a suggestion: why not let it small and cheap and you do an audio plugin with a great i2s codec like wolfson pi (drivers are made) or something better like an adau1761/adau1701 (linux drives in main kernel) with multiple inputs & outputs.

    With that you have a cheap as possible 8-core and a brilliant audio board to the people that don’t want to use an usb quality poor sound card.

    As far as I know they are EQUALLY free and open source (i.e not at all).
    In FOSS: ARM Holdings (Mali) = Imagination Technologies(PowerVr). = no support.

    Or show me the source for the Mali driver ?

    Mad props Luc Verhaegen and Connor Abbott.
    But as far as I know Lima has long way ahead.

    As far as I know Freedreno is progressed much further. Mad props Rob Clark.

    I’m sure that Olimex designers already have some idea of where they want to be in terms of A80 product, but since they haven’t yet received a datasheet from Allwinner, the plans are probably just bullet points at present.

    Although they haven’t explicitly stated that our feedback has the possibility of affecting their plans, Olimex has never struck me as the kind of outfit that would deliberately waste their customers’ time purely for PR purposes. I think we should assume that the feedback really will be taken into consideration (alongside their own requirements and insights) before plans are cast in stone. I believe it’s implied strongly enough.

    Your “two directions” echo the first of my posts above. I’m not very confident that these two directions can be satisfied well with a single product. It’s certain that they can’t be satisfied *optimally* for each of the two use cases with a single board, because to do so a board would have to be large and costly. That would please nobody, and it would be the kiss of death for sales.

    They warned about this directly (in the context of A80 LIME), namely “if we go in max features direction the board will become big and expensive”. I doubt they’ll make that mistake, since it’s clear that they understand the “Pi effect” — extreme low cost creates the market. I’ll just add that this effect applies to both types of use case. A high price would destroy sales in this new sector, which is why I suggested earlier that S/PDIF output could be on a separate add-on product to avoid affecting the price of the core board.

    Morgaine.

    Please don’t use the 1.27mm Headers, use 2.54mm instead!
    I don’t think that anyone wants to use all GPIOs on the chip, but if someone wants to tinker he don’t want to use any adapters but stick some sensors, buttons and led’s on standard connectors and play with it…
    I’m working in a small electronic components shop and if you have to explain a customer that the lime is very cool and cheap and the customer tells you he want to use a LCD (or anything else which uses gpios) you have to explain him that he has to use a special cable AND a special adapter for this he wont buy anything because the price is “much” higher then… (follow-up costs are not good in a customer pitch, as small as the increase in price may be…)
    So:
    – only a little bit bigger than the lime, much smaller than the a20 boards
    – 2.54mm connectors (one for LCD and two or three smaller (20-pin?) ones to connect peripherals?)
    – no audio (many customers ask for that but i think its wasted pcb-area and to much extra costs)
    – connectors on the pcb: HDMI, 2xUSB 2.0, 1xUSB 3.0, (MIPI CSI optional), GPIO+LCD, Ethernet, LiPo, DC-Jack

    I’m afraid I’d have to agree. 1.27mm dual-in-line are the worst, they are hard to use. If you have to go for 1.27mm pitch I’d rather have some JST type header where I can get cheap board-to-wire connectors, or even flat flex at 1mm or 0.5mm pitch since the flex and connectors are not too expensive. Anything other than 1.27mm DIL headers which are difficult to solder. Board-to-wire for 1.27mm DIL headers is exceedingly expensive too.
    2.54mm is most convenient, followed by 2mm. Please avoid 1.27mm.

    Hi,

    I think, the Lime form factor is great.
    The IO ports could be the same, and to the place of the SATA connector (As I see, the A80 has no SATA, if I am right.) an extension connector could be placed, with UART I2C and maybe SPI. In this way, there would be still an extension available in the boxed form.
    An optional Flash (or an internal SD card) would be great, and also the internal headers (with some easy connectors) for more extensions.

    Thank You, for asking us.

    Price determines sales more than anything else when the price is below the point where one needs to think twice (the “Pi effect”). This makes it interesting to consider what would be the absolute smallest feature set that would still be effective and interesting (albeit not for everybody), so that a rock-bottom board could be introduced that sacrifices almost everything for low cost. (This would not be a LIME at all, but a new type of OLinuXino.)

    There are many possible candidates for a constrained feature set, but one in particular appeals to me because despite its lack of features it is entirely perfect for its intended use case: the small Internet server. The potential audience for this could be quite enormous, because after all, the Internet is fairly popular. :P.

    An A80-based small Internet server would require no HDMI nor other video, just a console on UART0. It wouldn’t require fast storage either, because its gigabit Ethernet and USB OTG 3.0 allow fast network storage or fast USB storage to be mounted after boot. Only booting would require local storage, but this can be slow and cheap. Once booted then the fast non-boot storage becomes available so online operation will be very snappy.

    I’m running a tiny low-power x86 mini-ITX board off a USB-3.0 flash drive, and the speed of storage is absolutely astounding compared to any uSD card or indeed any USB-2.0 flash drive that I’ve ever used. This is only anecdotal, but it’s worth examining the possibility of keeping costs low by leaving storage to USB-3.0. Of course if USB-OTG allowed A80 boot devices then that would just be perfect, but I expect that it doesn’t so a uSD slot for booting would still be required.

    Needless to say, all the hardware interfacing headers could be omitted — remember that this would be a different category of product, so don’t complain that it lacks features that another product like LIME provides. In exchange for losing almost everything that isn’t dedicated to Internet service, it could offer more RAM, as that’s always welcome and important for servers feeding a gigabit pipe.

    Any changes or additions to this extremely cut-back spec for a cheap Internet server product? Or, any alternative feature specs for cheap A80 products that are not in the current OLinuXino “do everything” category so that prices can be kept very low to benefit sales?

    Morgaine.

      A80 board can’t be with shocking low price, let’s not forget we talk here for 8 core super duper powerful SOC which alone will cost more than RaspberryPi,
      two PMU surrounding ICs, Gigabit interface and 2GB RAM (RAM prices now are again in the sky) and we must be realistic

      if one is after low cost there are plenty of options but A80 will not be one of these like there is no low cost imx6 4 core board

      The hardware face recognition feature Allwinner speak in the video is interesting if open sourced, so people can further develop video and image processing features

        That’s unfortunate, if the SoC alone will cost more than a Pi. It takes the end product out of the petty cash niche where price is no barrier to sales.

        The general notion that there is room for a product optimized as an Internet server by omitting unnecessary features still stands though, at any price level. Likewise, there is room for a communications appliance with 2 or more NICs. The sheer number of people who have had to hack commodity routers because there is no suitable board available on the market is quite astounding.

        Perhaps both of the above ideas describe different versions of a hypothetical new product range — OLinuXino-INET. 😛

    my 2c … however much memory it is, it should be the fastest (reasonable/economical/power source) configuration the memory controller can support as that has the biggest impact on performance particularly with so many cores to keep busy (and could be a market differentiator if there is a difference). TBH with all that cpu power 2GB seems like a mismatch.

    Same for the gigabit ethernet.

    Short-list for a minimal ‘net terminal/entertainment console’ configuration:

    + 4GB ram
    + 1x or 2x sd-card, no on-board nand
    + 2x usb host, 1x usb otg (if that’s all it has, if more, then headers for extra)
    + ethernet
    + hdmi
    + expansion/lcd connector(s) that can can connect a daughter board

    – non-hdmi audio can be added via usb (find a small/cheap dongle that works well in linux/android, and sell that?).
    – bulk storage can be via nas rather than sata.

    Hi Olimex,

    As those boards with Allwinner processors are mostly used for multimedia, SPDIF connection is a must have. This board then could by a dlna server connected directly to amplifier with high audio quality. Personally i miss board with sata connection to make a dlna server with at least 2 hdd’s.

    Bets regards,
    Tomek

    Oh, daughter board, very good idea!
    Cheap daughter board to have 2.54mm headers on it 🙂 another possibility! But then with the headers of the lime so it can be used by both of the boards

    Hi Olimex,

    nice to hear that you are working on a A80 based solution!

    What i would need for my application:
    – Debian Linux (most important)
    – High CPU clock for the A15 Cores
    – 2GB RAM (Even 1GB would be ok)
    – 1 Gigabit Ethernet
    – 1 USB-Port
    – 1 Micro-SD slot
    – 2 x I2C
    – 1 x UEXT
    – >100 GPIOs (like LIME)
    – As small as possible
    – widest possible temperature range (larger CPU heatsink)
    – NO flash, HDMI, SATA

    Also very important: connectors for Ethernet, USB and Power on 1 single side, micro-SD on the other (= LIME-Design, NOT A20-Micro Design).

    In my opinion you can leave out additional SATA and Audio chips. Micro-SD Cards are large enough for every possible application and for more you can use USB oder network disk space. Audio is included in HDMI, that should be enough.

    For my part you could also leave out battery and OTG.

    So maybe you could make 2 versions:
    – minimal: like A20-LIME, but without audio,flash,sata, HDMI, Battery, OTG, 2GB RAM (for realtime,automation,webserver)
    – deluxe : with SATA, SPDIF, HDMI, flash, 4GB RAM (for multimedia)

    I have been waiting for a board that provides lots of computational power / Ram / Network but with out lots of extra stuff that I don’t need. An A80 with GigE and lots of ram in the “Compute Module” form factor would be perfect for what I want. Slap it on a dimm and build carrier boards for it that expose different capabilities. That way, people that want all of these features can have them, and people (like me) that don’t want them can get just the CPU/Ram/Flash/GigE and GPIO.

    I need a SATA and I don’t know who wouldn’t? If not, a mSSD Bay, The audio is important as well as the video, it needs hardware acceleration for use with Dolby! Like the tablet, the Micro SD Card should support 128GB and a larger Nand than 4GB at least 2GB RAM, Bluetooth 4.0, Wi-Fi ac dual band, why not have a board worthy of, or different models of it, HDMI in and out! If I was to build a board for sale it would have all the bells and whistles! It will sell and big!

    Device permitting:

    Please consider one or more mini-PCIe connectors. Multiple GigE. Multiple USB3.0 host, not necessarily with connector.

    Lack of SATA connector is a bother. What high-density memory interfaces could be put on the board instead? SDHC would probably be insufficient for most users who need mass storage.

    There is no need for a discrete audio connector and codec. Most of these devices will probably end up being run headless anyway; those that need audio will probably be connected to a screen. Please continue to use the high density connectors for GPIO.

    I am excited for the planned board, especially as it is coming from a more reputable company.
