How to find bss RAM usage using CCS4?

Carl19357

I'm using: CCSv4.2.4, SYS/BIOS 6.32.04.49, IPC 1.23.04.36, XDCtools 3.22.03.41 on Windows XP. I have a MSP430BT5190 connected to my computer through a MSP-FET430UIF.

How can I determine the amount of RAM used by statically allocated variables (bss section)? Can I tell which variables comprise the bss? I have a few BIOS features enabled and I'd like to know which ones are using up the RAM.

Thanks.

I found the linker generated project_name.map file underneath the workspace/project_name/Release directory. Using this I was able to disable BIOS features one at a time to discover where all the memory was being used. It turned out RTA was taking ~6k of bss RAM. RTA combine with the rest of the default BIOS features left almost no room RAM for my application.

The release notes benchmarks were also helpful but they would be more helpful if they included RTA. Still wondering if there is a tool that is part of CCS4 to aid in memory usage analysis.

Hi Carl19357,

I think the memory map is the best way to go.

Are you referring to the CCS Tools->Memory Map? Or the linker generated .map file?

The generated map file.
