    I appreciate your help, I followed this suggestion and bought two to see if I can write at least one,
    but I'm newer . and need to know where to find the program and how to record it.

    The Propeller in the YBox2 can write to the 24LC256. You need to use either the Propeller Tool or one of its 3rd party equivalents like BST plus a USB to serial adapter like the PropPlug to download to the Propeller. The source files for the YBox2 itself are on the YBox2 website.

    if I understood well,
    just use one of ybox2 I have put the new 24LC256, connect the USB cable
    into the adapter, and save a copy of the bootloader that already use.
    since this is the process that normally use to write programs,
    it seems pretty simple.
    grateful for your help.
    I'll try.

    works</SPAN>, all the widgets that I have and use DHCP or fixed IP is working !.

    But could someone explain to me why the bootloader does not work ?.


    its gets into a loop with noise and flashing red LED, can be, trying to get DHCP.
    can not be wrong in my DHCP server, because ( www.example.spin works) and since I already put up this mac with a fixed ip on my dhcp server.
    Fine, it is important that the process was simple for anyone who uses USB, and is resolved, since I do not use the bootloader.

    Without a lot more information about what you tried to do and how you have things set up, it's impossible to tell you why your bootloader doesn't work. I've used it without any problems just the way the instructions show.

    mike,
    I first want to thank your help.

    but I did exactly as proposed.

    I installed the widgets that use and works.
    www.example.spin I installed and ran fine.

    but when I write the bootloader it is looping trying to get ip.

    for your response I know I must be forgetting something, but the
    widget www.example.spin worked.

    I'll download the whole library and try again.

    but remember my job is complete,
    I fixed my ybox2</SPAN></SPAN>
