memory usage

[Alex]

Hi,
Probably a very simple question...
Where can I see memory usage (Flash, Ram) after compiling ?
From previous IDE's I could see it in map file if I remember well.

Thank you !

P.S.: still running v1.1, as I prefer not to update while running project

You can find that in the "Build messages" log.

You can also click at the map file to open it (see highlighted part in picture)

Thank you for your prompt reply !
Sorry, I was some confused...
On my install, Build log is providing the information:
"
Used memory resources:
  text   data     bss     dec     hex
  64372   1088   2140   67600   10810
"
somewhere in the middle of the log file,

whereas "build message" only displays

||=== Build finished: 0 errors, 10 warnings (1 minutes, 44 seconds) ===|

Probably you are using a generic (external) GCC Compiler.

I think what they are asking is if you could show RO memory usage (.text+.extab+.exidx+.data) separately in the same way you show RW memory (.data + .bss).  I know it's not perfect, but it would give users a feel for how close they are to running out of flash/ram with each build.

Ah I see, but the problem is that those memory segments are linker script specific. Although is almost defacto standard they may have, and can have, other names etc.

I use this linker flag to print out the memory usage of my STM32H7 project:
-Wl,--print-memory-usage

The output looks like this (in the Build log window):
