    Hai

    Has anyone tried running u-boot on top of LOLO on imx31 litekit board?

    I am able to compile the u-boot source for imx_litekit but i am not able to run?

    the commands used are

    export PATH="$PATH:/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/"
    export CROSS_COMPILE=arm-none-linux-gnueabi-
    make imx31_litekit_config
    make clean all

    I am downloading the image in LOSH using the command

    load srec //tftp//192.168.50.1/u-boot.srec
    exec

    Please help

    Arun

    Hi Arun,

    I was wondering why u-boot wont run via losh as well. And I get 'CPU halted' on some initialization routine when I try to run it via JTAG (i think that was at 0x87F10D34). Earlier, I inserted:

    #define CONFIG_SKIP_LOWLEVEL_INIT 1

    inside:

    u-boot/include/configs/imx31_litekit.h

    and now it outputs properly on the serial port and my JTAG debugger can now step throughout the code without any errors. I wish someone could explain why this happens.
