I am getting this message when compiling

*** ERROR L107: ADDRESS SPACE OVERFLOW
    SPACE:   DATA
    SEGMENT: _DATA_GROUP_
    LENGTH:  00001CH
Program Size: data=112.1 xdata=0 const=0 code=4492
Target not created


while i have 8192 bytes of On-Chip Memory,
below size of 4096 bytes ,there is no problem
and i have selected AT89x52.h header file.
Memory Model: Small
Code Rom Size: Compact
So what is the problem??

    Please start your own thread with a new question. Don't dig up ages-old threads to continue them with a vaguely-related question (that has a different answer).

    To your original question: Are you sure that you are using the full version of uVision, and not one that is limited in code size ? Limited versions of uVision come with many development kits.

    And, if you think that an old thread may be related to your new question, then simply place a Link to it in your new thread!

  • ok, i will start a new thread.
    secondly, i am using full version.
