iMX233-OLinuXino-Micro the EUR 20 Linux single board computer is routed nice and clean

We finished the iMX233-OLinuXino-Micro routing and the files are push to GitHub.

Tomorrow we will run the prototypes, we were very tempted to see if we can make the design 2 layers first, we placed the memory directly under the iMX233 processor so the signal paths are very short and should be not problem for 133 Mhz, but the cross talk may play bad joke for us with no ground planes to separate the signals. Well crossing fingers and … we’ll see in few days on what frequency it will run.

Meantime the software developers did enormous amount of work. The iMX233-OLinuXino have now Open Embedded Layer and Raivis now is having fun with Linux Kernel 3.3 trying to move the 2.6.x drivers to the latest Kernel.

    It will be able to host an Arduino on USB port (/dev/ttyACM0 for UNO or /dev/ttyUSB0 for Duemilanove)?

      Er…. what do you mean by “host”? Talk to it over a virtual COM port? If so, there would need to be an ARM FTDI driver for it (the Duemilanove), or the “standard” driver that’s on i386-Linux to run on arm-Linux (I’m assuming that the latter is easily doable/done).

      If by “host” you mean run the IDE, cross-compile to it and download, then you’d need Java, an ARM-crosscompiler-to-AVR gcc toolchain and an ARM version of avrdude. I’m not sure where any of those pieces are (I’m doubting all of these exist though), nor if this board is going to have the headroom to do all of these acceptably.

      My guess is that you don’t want this as your development “host”/platform… it’s not a PC replacement — just in case that’s what you were getting at…

        I don’t want a development chain on this board. Your first paragraph answered to my question (ARM board as an USB Host) – so, I conclude that those drivers are not available yet…
