Re: Code size & data size

Doesn't your map file include a part like this:

 

*** Total Section Size ***

 

RAMDATA SECTION:  0000041d Byte(s)
ROMDATA SECTION:  0000004a Byte(s)
PROGRAM SECTION:  00000850 Byte(s)

 

Note, the numbers are hexadecimal.

Re: Code size & data size

The P* ones are program, D* is r/w data, B* is bss (uninitialized data), R* is read-only data, S is stack.

Re: Code size & data size

And the C sections are constant data.If you have a look at chapter 9.1.2 of the compiler user's manual you get a quite good explanation about section names and also how to change them.

And if you use the linker option -show=total_size you get the summary I showed before.
