    Yes, it's me again. Still tracking down whatever.

    Here's a trace of a couple of losh commands:

    losh> hd /dev/serial_eeprom

    Assuming that shows up ok.... it's a hex dump of the /dev/serial_eeprom that we create in the WinCE BSP quick start guide. As you'll see, I ran the command twice and got different results.

    Is this a bad board, a bad chip, or what?

    Thanks,

    Marc

    Hello Mark,

    The issues you are describing are consistent with other A400 customers with CPLD code prior to 2.8. Please refer to the PCN for further explanation and instructions to resolve this issue.

    In any case your card engine should be returned to Logic for CPLD update. Please send an email to platformsupport@logicpd.com. We will issue an RMA number and shipping instructions. The issue can be resolved in a couple of days with overnight shipping on both ends.

    Please refer to the email below, which you may have already received from the card engine distributor.

    Regards,
    Andrew Wawra
