I have PC, so intel processor and BCC compiler ,i have Watcom tool where we can open project file and make, run. so based on this how can i measure footprint? Is possible in PC or i should have download some GCC based ARM cross compiler? ---

I want RTOS size only. That include (Source folder only) i suppose. I want that size only. i have flash in processor example ARM7. To flash it i should know size of RTOS. How can i get it? ---

I counted size from Map file ( in Segment area : segment , address , size) it is nearly 10 k. Is it right? ---
