    We have recently bought the MDK. I am only starting with it

    The problem is with saving of environment with the u-boot
    When rebooted, it goes to default environment.
    Is it the fault with NAND, or is the problem with u-boot version.
    I have not updated anything on the device, it runs the default factory u-boot.
    Has anybody experiences these problems?

    Here is the log:

    The device carries u-boot version:
    OMAP34XX LAB # version

    U-Boot 1.1.4 (Mar 14 2008 - 15:08:13)

    OMAP34XX LAB # printenv ipaddr
    ipaddr=128.247.77.90
    OMAP34XX LAB #

    Ok, trying to change the address:
    OMAP34XX LAB # setenv ipaddr 192.168.1.100
    OMAP34XX LAB #

    Checking:
    OMAP34XX LAB # printenv ipaddr
    ipaddr=192.168.1.100

    Which is Ok
    OMAP34XX LAB # saveenv
    Saving Environment to NAND...
    Erasing Nand...Writing to Nand... OMAP34XX LAB #, saving:
