Warning L5 - BL51

Petr Jurcik

Hello,
when I compile my application these warning messages from linker(BL51) are occured:

*** WARNING L5: CODE SPACE MEMORY OVERLAP
FROM: 0043H
TO: 0066H

*** WARNING L5: CODE SPACE MEMORY OVERLAP
FROM: 005BH
TO: 0066H

Can I ask you for advice/suggestion how fix these problems?
Probably some problem with interrupt vectors (0x43H - RF, 0x5BH - Timer3) - but I dont know how to fix it.

Thank you, Bye Peter

    Look in the map file to see what's overlapping.

    Thanks.
    From map file(*.m51):
    * OVERLAP * CODE 0043H 0003H ABSOLUTE
    * OVERLAP * CODE 005BH 0003H ABSOLUTE

    I shift the possition of interrupt vectors(INTVECTOR(0x0200)) and the program code (CODE( 0x1000)) in my application. And I use the RF transmission fuctions(SPP protocol) in my program (this function use the interrupts RF(0x43H) and timer3(0x5BH)).But when I make the dump of the memory, these two interrupts are not shifted on the possion 0x2043 and 0x205B but stay on 0x0043H and 0x005B. Maybe this it the problem.How can I fix it?-compile the hal and cul libraries with the other setting?
    Thanks, Peter

    Sounds like these segments are created in an assembler file. Maybe you should search for CSEG at 0043h and CSEG at 005Bh in your assembler files.
