HI Champ,

For example I have below structure variable define, after compiling , there just has gMotorVars addess in the map file, does it possible to generate all the variable address with in this structure like gMotorVars.Rr_Ohm and gMotorVars.Lsd_H in .map or in .out file?

typedef struct _MOTOR_Vars_t_

{

float_t MagnCurr_A;

float_t Rr_Ohm;

float_t Rs_Ohm;

float_t RsOnLine_Ohm;

float_t Lsd_H;

float_t Lsq_H;

float_t Flux_VpHz;

}MOTOR_Vars_t;

volatile MOTOR_Vars_t gMotorVars;

Hi Johnson,

The map file only defines the start address of the struct. It is unnecessary to list the offset of all the members if the struct.

In CCS, the watch expression window will show the offset or address of the all the members.

Hi QJ,

Customer need to do XCP calibration, so need to know each variable name and address.

Please advise it is possible or not?

Hi Johnson,

The map file gives the start address of the STRUCT, and does not list the address of its members..Customer can easily calculate the address of STRUCT members.

Hi Johnson,

I don't think compiler can output those member addresses to map file through the compile/link settings.

Please check utility global_types_gen from the cg_xml package. This utility takes an executable file as input, and uses the debug information in that file to discover and display the layout of every structure in the program.
