A10-OLinuXino first prototypes are assembling


Image

A10-OLinuXino routing took 3 months but this is really monster board and instead in 6 layers as per Allwinner recommendations we routed it at 4, so we now will have to see if it will work at all as it doesn’t quite blindly following the official Allwinner routing🙂

Another experiment we are going to do it to see if A10 can work with 2GB RAM memory. We asked Allwinner if this is possible and the response was: yes it may be possible but we never try it as our market is low cost tablets and when the memory rise to 2GB the price is not low cost.

At Electronica we spoke to lot of memory suppliers, Memphis is partner we work for a long time and they offered us 4Gbit DDR3 memories to try to our boards.

If we succeed this will be the first A10 board with 2GB RAM.

I asked Henrik Nordstrom what he think about this and his reply was:

From a DRAM controller perspective it do look like it should work, both in single and dual rank configurations. Configuration of the DRAM controller is very flexible, and physical address space have 2GB DRAM at 0x4000000-0xC0000000.

A bit unsure about the virtual address space used by the Linux kernel.
There DRAM normally starts at 0x80000000 and there is I/O and other things in the upper 512MB region not leaving room for a full 2GB DRAM. But this is most likely only a configuratoin issue.

So next week we will have quite interesting time hacking A10.

    On your git I found pdf of schematic. Will you publish the PCB CAD files?

    Good work! But what about pricing? Or is it to soon to ask about this?

    I’m crazy about the olimex products. Best quality price ratio.

    i’m very excited about the A10. I really need sata. Will this have a sata connector?

    I don’t like the name.

    Do you have an estimate when this board will be available to customers? Will you offer it as a A10-OLinuXino-WIFI version?

    How is the testing going? Does the 2GB RAM work yet?

      I know this is not business as usual but I would really like it if this board would have a cool pcb logo just like the duinomite board and the raspberry pi. I ordered 2 duinomites. I’m really happy with the excellent performance-price, but the cool image with the logo just finishes the concept.

    What about a new quad-core board with allwinner a31 (quad core a7), and 2gb ram? it would be great😉 and please release the a10s-micro….

      Unfortunately Allwinner do not care at all for Linux and all their distribute is Android SDK and image, this is their main market and this is where they are focused.

      A10 community Linux support (Linux-Sunxi.org) was made mostly due to the lot of cheap Allwinner tablets and IPTV sticks in circulation and one major code leak from Allwinner tablet distributor in EU.

      For this new A7 4 core device I can bet they will not release any GPL compliant Linux Kernel and their SDK will allow you just to build Android image with lot of binary blobs inside, so we will probably pass on this, until Allwinner decide to support Linux not only Android.

    So let me know what you are trying to do and what you actually did🙂
    Are you still working for the memory support? I’d hope to receive further news.
    Good luck😉

      the prototypes are assembled, we are stuck with the DDR memory initialization as our schematic is slightly different than original Allwinner board and there is NO any description of the DDR memory controller registers so we are now doing some guess work based on what is available as sources
      this may take a while🙂 so do not hold your breath

    Hello,

    I’ve also designed an A10 base custome board.I’m wonder how to perform DDR3 calibration procedure.I couldn’t find out any information about the DDR controller such as making up timing parameters, read/write leveling… How could you do DDR3 initialization for the olinuxino board ?Is A10 the same with A13

    Hello,

    how’s the A10 board testing coming along?

    Also what is the size of the board? larger than teh ITX A13?

    I see some irregularly placed mounting holes. How was the layout chosen? Perhaps they are now ITX compliant?

    Hello, Any update on this project? I am looking for a SFF board with SATA connector.
