    I still try to compile Linux 2.6.22 kernel + zyzyis' MX27 litekit patch for the Linux 2.6.22 kernel. However, I couldn't get a build becuase of compilaiton errors: " CLOCK_TICK_RATE" is not defined.
    The arm compiler I use is the one downloaded form Logicpd website (gcc version 3.4.3).
    I know many of you already passed this stage. I'd be very apprecivative if you can help me out.
    Thanks!

    I use the one provided with freescale mx27ads BSP which is called "arm-v4t-linux-gnueabi- " or something similar.
    And it works fine.

    Thanks so much for the prompt reply! I will try that out. Do you use Cygwin or Linux? BTW, are you able to get USB port working for MX27Litekit? I'd like to use the board estimate how fast data transferring speed can be. It is said about 48MBps rate for USB2.0 theorectially. But in reality, the rate can be much slower.

    I use Linux, I don't think cygwin is a good environment for embedded linux development and It will probably bite you sooner or later.

    I am working on USB right now, it seems that it will not work "as it is" and I will have to make some fixes. But I can't swear that because I am still looking for a female/female USB adapter for testing.

    USB testing has gone succesful. I have tested mini USB OTG port. It can act as a host, reading a Memory stick flash, or it can act as a gadget getting a host PC recognize it as a Storage Media or a Network Card.

    Regards.
