BL51: ERROR L107 (ADDRESS SPACE OVERFLOW)

Information in this article applies to:

• C51 Version 6.01

SYMPTOMS

I keep receiving the following error message (or one similar to it):

*** ERROR L107: ADDRESS SPACE OVERFLOW
    SPACE:   CODE
    SEGMENT: ?CO?MAIN
    LENGTH:  8000H

CAUSE

This error message indicates that a segment named ?CO?MAIN, which is a COnstant in the MAIN segment, is 8000h bytes long and will not fit in the remaining CODE memory space. This may be an indication that your program is growing too large or it may indicate that you need to increase the amount of ROM or RAM space available to your target hardware.

RESOLUTION

To resolve this problem:

• Reduce the size of your code and data segments by hand optimizing and/or using smaller data types where possible.
• Increase the size of the XDATA and/or CODE space. Refer to BL51: SPECIFYING CODE AND XDATA RANGES for more information.

MORE INFORMATION

• Refer to Error L107 in the BL51 User's Guide.
