    Is it possible to read the contents of /dev/serial_eeprom from WinCE?

    Does anyone know the physical address of the /dev/serial_eeprom? I would like to use MmMapIoSpace to access it, but I need the starting physical address of the I/O range.

    Hello Frank,

    Have a look in the Card Engine IO Controller Specification from Logic's website, it implies that you have to bit bang the EEPROM by writing CS/SCLK/TX/RX pin levels to address 0x70A0 0000 (see the spec, page 6, for bit positions).

    See the discussion forum thread 'LEDs on SDK' for code for accessing CPLD registers, grab the data sheet for the EEPROM to work out addressing method. Then curse Logic for a while for not bringing out the SPI interface on pin headers for probing.

    I haven't actually tried accessing the EEPROM, but this is the way I'd go about it. Is there a better way maybe? anyone?

    HTH,

    Andreas

    Logic used to ( a couple of weeks ago) have a lpd_LH7A400_EEP_beta_001 driver file available on their website. Now it's gone! Is it coming back?
