    Hello to everyone,

    I have a project running on an H8-3664 (TINY) Processor (Renesas former
    Hitachi), with 1k RAM. I'm using HEW 1.3(IAR 3.50a). My current Program with
    3664, I have 280Byte free (tested with "unsigned char test[280];")
    Now I need to upgrade to H8-3687 with 3k RAM. I changed the part in the
    linker (loading the 3687.seg downloaded from Renesas Homepage. Now I can
    access 1560 Byte, not 280Byte+2K ?? Where is the rest of the memory?? When I
    try to use more Memory ->Error[16]: Segment UDATA1 is too long for segment

    The only changing I want to do is creating a Variable of the size of
    What is going wrong?
