    I am connecting to the development board using Platform Builder and KITL.

    After downloading I execute the image from losh using:

    losh> exec share_eth:1:dbg_enet:91C111:dbg_enet_base:0x09000000:dbg_enet_irq:0x00000008:kitl:true

    The following error message appears in the Platform Builder Debug output screen:

    Loaded 'lpd_smsc91c111_async_pxa270_50_.exe', no matching symbolic information found.
    712 PID:e1bc172e TID:e1bccf12 SmSC_91C111: Resource conflict! Base address (0x09000000) in use by KITL.
    713 PID:e1bc172e TID:e1bccf12 SmSC_91C111: Driver will not initialize.
    Unloaded symbols for 'lpd_smsc91c111_async_pxa270_50_.exe'

    I am trying to use Winsock (setting the development board up as a server) to exchange data with my development PC. Hence, I used the "share_eth:1" parameter. I am having problems connecting the PC and development board programmatically while also using the Ethernet interface for KITL. Any suggestions?


    Also, what is the name of the serial channel to use with the “dbg_serial” parameter to the “exec” command? I would like to direct debug output to the Tera Term window if possible.

    Thank you.

    Guy,
    If you use the 'share_eth:1' boot parameter, the lpd_smsc91c111_async_pxa270_50 driver will automatically not load. So, you have to chose whehter you want to use the shared ethernet interface or if you want to use the actual ethernet driver.

    In this case, you should be fine because KITL will be connected and you will be using the shared ethernet interface. This does not cause any issues, the ethernet driver just won't load.

    Thanks,
    -Mike

    Guy,

    As a follow up to the second part of your posting here is an example bootstring that I use:

    exec rtc:rtc_pxa270:dbg_serial:PXA270_FFUART:disp_num:8

    Be sure to check the correct "disp_num" parameter in LogicLoader by typing 'help video-open' in LogicLoader to get the correct display number for the kit that you are using.

    Thanks,
