RN8 memory usage view, how many FLASH & RAM do I use (with Codewarrior 11)?

sebe — Wed, 09 Jan 2019 09:40:35 GMT

Hello,

I have a S9S08RNA8 µC and I use Codewarrior 11 for my application software.

I seach now for a way to see how many memory (flash and/or RAM) my µC is using. I don't men the memory view while debugging with the codewarrior. This is working fine.

I mean a way to see in percent or in kB how high my memory usage is. Is there another programm instead of CW11 which can do it?

Any other suggestions?

Hello Sebastian Felix,

CodeWarrior can generate a map file after a SUCCESSFUL build.

In map file, it summarize the used memory sizes based on the section type. see below demonstration:

Yes, thanks. This helps me.

I checked it with my softwares and it looks okay for me. READ_ONLY is flash+EEPROM and READ_WRITE looks like the RAM.

NO_INIT, is something what will not be initialized. Somehow all my projects have the same NO_INIT size, 225. I think this is µC specific, which will be different If I take a larger or another type of µC.

Perfect, thank you!
