Flash.elf.xMAP file description in code warrior 8.3

[carlkaczor]

I am using code warrior 8.3. My project compiles and builds, a .MAP file is generated. I am trying to figure out the program size and RAM usage but I can't seem to find these items. I am used to the CCS compiler where after every successful build it displays these stats.

Thank you in advance

Hi, Carl,

Regarding your question on how to figure out the program flash size and data RAM size, I think the *.elf.xmap file is the only way to get the program size and data ram size the application code utilizes.

You can read the end of the map file to understand the program flash and data RAM utilization.

The program flash size used is 0x0086+0x47B5=0x483B words, in other words, the program flash occupies from P:0x0000 to P:0x483B.

The data RAM used is from X:0x0000 to X:0xD71, the size is 0xD71-0x0000=0xD71.

The independent stack is from X:0xEA0 to X:0xFFF, the stack size is 0xFFF-0xEA0=0x160

Hope it can help you
