    I've upgraded LogicLoader and can download the "Win CE 4.2 Demo Show Image for SH7760-10" NK.BIN found on the download site using BOOTME. WinCE hangs during its bootup. Here's the TeraTerm session (slightly abridged):


    losh> ifconfig sm0 dhcp
    Starting DHCP on sm0
    losh> bootme

    Device's name is LoCE_30124.
    Sent BOOTME 1

    Platform does not support or does not require extension DRAM.
    Reported RAM installed is 0 MB


    A memory test shows I have about 63MB of RAM yet the loader reports zero.

    The products are:

    Card Engine SH7760, Zoom SDK Baseboard, & 6.4" VGA Display.

    I feel like I'm missing something simple here.

    I did manage to get this working if I loaded the NK.BIN from a CompactFlash but not if I boot via BOOTME. Is there a reason BOOTME wouldn't work?

    I guess you can make it work by inserting the CF card into the slot while excute boot command.

    The evaluation NK.bins typically require a CF card for the Hive Registry. It will not boot without a CF card.
