    Hi,
    What's the size of the serial eeprom? 128 bytes? And is there a maximum length to the boot parameter string (to wince)?
    Thanks,

    Michel,

    I believe the size of the eeprom is 128 bytes. To be sure, you can us the "hd" (hex-dump) command within the LogicLoader as follows:

    losh> hd /dev/serial_eeprom

    This will output the entire eeprom and you should be able to tell really quickly how large it is.

    There is a miximum size of 1Kbytes (1024) bytes for the boot string for WinCE. This size _does_ include the terminating NULL character. So, you really only have room for 1023 characters plus the NULL character.

    I realize that you might be feeling that you are running out of room in your eeprom for the boot string. Please keep in mind that quite a few of those parameters won't be used in a production device. If you don't have enough room in the eeprom, just write a text document that includes the exec command as well as the command-line parameters that you want to send to the WinCE kernel. You can then just send this text file directly to the losh prompt and it will execute it for you.

    Regards,

    Hi Mike,
    Yea, I looked up in the h/w documentation and discovered the 1Kb limitation. Thanks for confirming.
