Since these segments // contain objects which already have a fixed address, // they should not be mentioned in this linker command // file. // _C -- Constants (ROM). // _I -- Initialized data (RAM). // _ID -- The original content of _I (copied to _I by cstartup) (ROM). // _N -- Uninitialized data (RAM). // _Z -- Zero initialized data (RAM). // // Note: Be sure to use end values for the defined address ranges. // Otherwise, the linker may allocate space outside the // intended memory range. //************************************************************************* //************************************************ // Inform the linker about the CPU family used. //************************************************ -carm //************************************************************************* // Segment placement - General information // // All numbers in the segment placement command lines below are interpreted // as hexadecimal unless they are immediately preceded by a '.', which // denotes decimal notation. // // When specifying the segment placement using the -P instead of the -Z // option, the linker is free to split each segment into its segment parts // and randomly place these parts within the given ranges in order to // achieve a more efficient memory usage. One disadvantage, however, is // that it is not possible to find the start or end address (using // the assembler operators .sfb./.sfe.) of a segment which has been split // and reformed. // // When generating an output file which is to be used for programming // external ROM/Flash devices, the -M linker option is very useful // (see xlink.pdf for details). //************************************************************************* //************************************************************************* // Read-only segments mapped to ROM. //************************************************************************* -DROMSTART=00000070 -DROMEND=0001ffff //************************************************ // Address range for reset and exception // vectors (INTVEC). // The vector area is 32 bytes, // an additional 32 bytes is allocated for the // constant table used by ldr PC in cstartup.s79. //************************************************ -Z(CODE)INTVEC=00000000-0000007F //************************************************ // Startup code and exception routines (ICODE). //************************************************ -Z(CODE)ICODE,DIFUNCT=ROMSTART-ROMEND -Z(CODE)SWITAB=ROMSTART-ROMEND //************************************************ // Code segments may be placed anywhere. //************************************************ -Z(CODE)CODE=ROMSTART-ROMEND //************************************************ // Original ROM location for __ramfunc code copied // to and executed from RAM. //************************************************ -Z(CONST)CODE_ID=ROMSTART-ROMEND //************************************************ // Various constants and initializers. //************************************************ -Z(CONST)INITTAB,DATA_ID,DATA_C=ROMSTART-ROMEND -Z(CONST)CHECKSUM=ROMSTART-ROMEND //************************************************************************* // Read/write segments mapped to RAM. //************************************************************************* -DRAMSTART=40000000 -DRAMEND=4000FFFF //************************************************ // Data segments. //************************************************ -Z(DATA)DATA_I,DATA_Z,DATA_N=RAMSTART-RAMEND //************************************************ // __ramfunc code copied to and executed from RAM. //************************************************ -Z(DATA)CODE_I=RAMSTART-RAMEND //************************************************ // ICCARM produces code for __ramfunc functions in // CODE_I segments.
