Alternative Linux images for LIME and LIME2


A20-OLinuXino-LIME2-1

Igor Pecovnik has created optimized Debian image for Cubie board named Cubian, he asked for sample board and we sent him LIME2 so few days after he received the board he generated optimized Debian image for LIME2, you can see the instructions and images on his blog: http://www.igorpecovnik.com/2014/11/18/olimex-lime-debian-sd-image/

A10-OLinuXino-LIME-1

Remy van Elst did minimal Debian 7 for A10-OLinuxino-LIME https://raymii.org/s/articles/Olimex_A10-OLinuXino-LIME_minimal_debian_7_image.html

    Incredible job from the community!!!
    Any chance to solve the gigabit issue ?

        Are there any references to the gigabit limitation? I have never read about it before. Only thing I know is the 50% limitation of the freescale i.mx6

        I discover this issue today in other board, CuboxTV, because he explain this problem in his Web description of the product.

        The only ARM SoCs I’m aware of that sature GBit network speeds are Marvell’s Kirkwood and Armadas. They also have superiour SATA throughput (unlike the A20 which seems to have a write limitation of approx. 40 MB/sec). This is the main reason almost all ‘entry level’ NAS devices are built with them. And they’re way more expensive compared to an Allwinner design.

        For normal use cases the network performance one can achieve with an A20 and its integrated GMAC is more than enough. And sometimes GBit networking is a disadvantage itself. With 100 MBits/sec one can use cheap passive Power-over-Ethernet injectors/splitters🙂

    Bananian has some basic support for Lime2: https://www.bananian.org/hardware

    But in fact it’s all about exchanging script.bin prior to first usage on an Olimex board. It will take a few weeks to further tweak the settings (increasing voltages seems to be a good idea). Regarding GBit network speed: It all depends on some tunables and then you can achieve throughputs in one direction close to the theoretical maximum. In the other direction you won’t exceed approx. 550 MBits/sec. Almost all stuff I collected here http://forum.lemaker.org/thread-7102-1-1.html applies to the LIME2 as well. Given the price of the platform the performance is really not that bad.
