HI everyone, i am new to STVD and stm8, cosmic C

i follow the thread of this https://my.st.com/public/STe2ecommunities/mcu/Lists/stm81/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/stm81/Output%20Size%20in%20IDE%20%28ROM%20%20RAM%20Usage%29&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580001E3853D9DB932A46A3FE4CD15CAB46FB&currentviews=2189 and it outcomes : ---------- DEBUG\TEST_ALL.MAP start 00008080 end 0000808c length    12 segment .const start 000080cf end 00009b16 length  6727 segment .text start 00004000 end 00004000 length     0 segment .eeprom start 00000000 end 0000003b length    59 segment .bsct, initialized start 00008094 end 000080cf length    59 segment .bsct, from start 0000003b end 0000004d length    18 segment .ubsct start 0000004d end 0000004d length     0 segment .bit start 0000004d end 0000004d length     0 segment .share start 00000100 end 00000100 length     0 segment .data start 00000100 end 00000100 length     0 segment .bss start 00000000 end 0000064b length  1611 segment .info. start 00000000 end 0000a1cc length 41420 segment .debug start 00008000 end 00008080 length   128 segment .const start 0000808c end 00008094 length     8 segment .init from the above do it mean 6727 , 6.7K byte flash? And for the data, it show 0 ? And i encounter that once i add more variable, the program run strangely without warning me the excess of RAM use ? Thanks for help , thanks

Do you have any global variables?

I you have local vars, these are allocated on the stack and compiler doesn't warn about stack overrun.If possible try to use global data instead of local data on the stack.

Posted on December 12, 2014 at 08:39 Hello, your map file shows that you are currently using (12+6727+59+128+8) bytes of FLASH (rom, code) and (59+18) bytes of RAM Regards, Luca
