I am using philips MC2 controller. Following are the memory classes defined: ACTIVE MEMORY CLASSES OF MODULE: BASE START END USED MEMORY CLASS ========================================================== 000000H 700000H 77FFFFH 00A2B6H HDATA 7F0000H 7F0000H 7F04FFH 000100H EDATA 000000H 000000H 0006FFH 000440H XDATA 910000H 910000H 91FFFFH 01000BH CODE 900000H 900000H 90FFFFH 0000FCH CONST 000000H 910000H FFFFFFH 01975FH ECODE 000000H 910000H FFFFFFH 000002H HCONST 000000H 900000H 90FFFFH 000EFDH ECODE_CFI LX51 LINKER/LOCATER V3.60 10/09/2003 14:59:56 PAGE 4 7F0020H.0 7F0020H.0 7F002FH.7 000007H.3 BIT 7F0000H 7F0000H 7F007FH 000068H DATA 000000H 000000H 0000FFH 000005H PDATA 7F0000H 7F0000H 7F00FFH 000002H IDATA I am getting address overflow error for code memory. If i remove some portion of code then it fits in the CODE memory Class. otherwise it overflows. The expectation is that the linker should be using ECODE instead. What can be reason ? I can only use memory in the range 0x900000-0xFFFFFF for code.
The linker does not move segments from one memory space to another. It merges segments that are located in same memory class but it does not move them to a different memory class. The memory class (code, ecode, xdata, ...) of a segment is determined when that segment is created (in the assembler or in the compiler). When you looked at the Memory Map Of Module did you notice which of your program segments were located in CODE memory? Jon
