    First bootup for me led to some problems Logic has confirmed. The CE demo image is buggy with respect to USB devices plugged in (mouse kbd etc). What happens is the mouse works for a few mins, then the image freezes and must be rebooted. Logic is aware of the problem and is addressing it last time I talked to them.

    Paul,
    The USB host issues are resolved. The problem was in hardware. NXP changed the data sheet for the ISP1504 from the time we developed the board to the time we produced beta units. To solve the issue, XTAL2 pin must be removed from ground. Our next run of boards has this issue corrected.
    If you wish to attempt to rework your product, here are the steps:
    1) Device U16 and U17 must be temporarily removed from the board.
    2) Trace between the GND pad and pin 16 must be cut.
    3) Put U16 and U17 back on the board.

    If you have USB function related problems, you may also have to cut the trace leading to pin 17 on U17 and then tie the pin to the nearest 2.7V power location.

    Motraat,
    The sample NK.bin files on the LPD website are all built with the displays and touch driver included. Because you don't have a display, the touch driver is probably timing out. Instead of using a sample NK.bin you could build a custom image that doesn't include graphics or touch and your issue would be resolved.

    KurtL,

    Thanks for reply!
    We have ordered QVGA LCD. But I have following query:

    1) I installed cygwin and then gnu tool chain.
    2) I am able to see /logicpd folder created in cygwin drive. Newly created folder, logicpd contains gnu tool chain v3-1 which further has arm-elf in the folder.

    But when i am not able to execute gcc commands inside the folder arm-elf. When I tried to compile simple programme with following option this gives error as:

    $ gcc -mcpu=arm1136jfs hello.c
    cc1: error: bad value (arm1136jfs) for -mcpu= switch

    Any idea what I missed?

    You want to try "arm-elf-gcc -c -mcpu=arm1136jfs hello.c" since "gcc" is using the system x86 compiler.

    Note the "-c" which tells the compiler to just compile the code, not link it. You'll need to provide startup code and a linker command file since you need to tell the linker where to link it for.
