    I have successfully built my image for the LH7A404-11-504HC card engine. When I attach to the device via Platform Builder 5.0 and download the image all appears fine except after successfully loading the image I execute the following command from the boot loader :

    exec dbg_serial:A404_UART:dbg_enet:91C111:dbg_enet_bas e:0x70000000::share_eth:1:disp_num:6

    The screen appears to initialize but nothing is shown, status LED0 remains on and status LED1 is glowing slightly with what appears to be a continuos rapid blinking. The output from the command is as follows:

    kernel cmdline: 'dbg_serial:A404_UART:dbg_enet:91C111:dbg_enet_bas e:0x70000000:
    :share_eth:1:disp_num:6:kitl:true:ip_addr:172.16.0.68' at c00c0100
    disabling mmu.

    Where it appears to hang...this output varies greatly from when I have had other images booting properly.

    Any help or suggestions would be greatly appreciated.

    Tom,

    I think this is what you're missing:

    dbg_enet_irq

    The boot string parameter "dbg_enet_irq" must be properly defined (0x00000016) in order for IRQA to function with no other CPLD interrupt sources registered.

    Give this string a try.

    exec dbg_serial:A404_UART:dbg_enet:91C111:dbg_enet_base:0x70000000:dbg_enet_irq:0x00000016:rtc:rtc_a404_int:share_eth:1:disp_num:6

    Aaron thanks for the quick response. I did as you suggested but I'm still getting the same response with the following loader output:

    kernel cmdline: 'dbg_serial:A404_UART:dbg_enet:91C111:dbg_enet_base:0x70000000:d
    bg_enet_irq:0x00000016:rtc:rtc_a404_int:share_eth:1:disp_num:6:kitl:true:ip_addr
    :172.16.0.68' at c00c0100
    disabling mmu.

    Do you have any other ideas?

    Will your image boot with this string?

    exec rtc:rtc_a404_int:dbg_serial:A404_UART:disp_num:6

    No - still no luck. Same response with the following loader output:

    kernel cmdline: 'rtc:rtc_a404_int:dbg_serial:A404_UART:disp_num:6:kitl:true:ip_a
    ddr:172.16.0.71' at c00c0100
    disabling mmu.

    Tom,

    My guess is that there is a bigger issue going on here with the way that you built your platform. I would recommend going through the BSP Quickstart Guide, it can be found under WinCE Documents on the product downloads page for the A400. This will enable you to walk step by step through the proper procedure for building an example windows CE image.

    If you require further assistance Logic can always help with WinCE development Q and A under a support contract. Please contact productsales@logicpd.com to discuss purchasing one.

    Thanks,
