Hi,

How do I get the footprint (RAM and ROM size) of an RTEMS application?

That sounds like it came from ls. That's the file size with debug info. Use
the command TARGET-rtems4.xx-size on the exe to get the code, data, and bss
size.

On top of that is the size of the C program heap and memory for RTEMS OS
objects and stacks.


Is this the right footprint of an RTEMS application? Also is that the RAM
size or the ROM size?


Neither. Size on disk with extra information.
