September 11, 2012 - 5:29pm Guest	Hi, I am trying to use the startup_stm8.asm file for Startup of STM8. The usage is mentioned in the Application Note:AN61. When I added the file to my project, I noticed in the memory map file the following: Total Data storage requirement: 0204H (516) My project is still empty and this data requirement is coming from startup_stm8.asm. Why is it taking up all the RAM?? May be I do not know how to use the Startup code. What I am atleast sure is I am not left with any place for DATA storage. Can you please help me understand this. Thank you, Pradeep .. .. .. .. .. .. ..

If you don't use it, the Raisonance "smart" linker will guest that for single while(1) your program doesn't need any start-up and any stack! That the reason why it is shorter. Regards, Stéphane
