Hi to All
I'm just begining to use this uC working with STVD and Raisonance toolchain (compiler version is: RCSTM8 COMPILER V2.17.09.139 Lite (16 Kb code limited), linker version is: RLST7 LINKER/LOCATOR V2.17.09.139).
I have some doubts on the map file, from manual of ST it says that memory regions from 0x00 806C to 0x00 807C are reserved, but in the map file says another thing (see below partial map file)
My INTSECTION0 starts right on 0x00 8060, is this correct or not?
It seems strange for me.
Thank's to All.

Hi Ipur,
Your map file looks ok. On STM8S103 addresses 0x8000-0x807F are reserved for 32 interrupt vectors. If they are not used their ROM space can be used as standard flash (although it does not look as a good idea, as there is plenty of ROM anyway).
Do you have a specific issue with the linker?
Regards,
Bruno
Hi Bruno
Thank's a lot for the replay. For your question I have no issue with the linker and everything seems working fine!
Anoter question if I canin this post is: For an ISR function for Reset is the only way to implement it on the start-up file only or may I make it in a C file?
Thank's for the bet support!
Ciao
Franco
Hi Franco,
The reset handler can only be handled through the startup file. The sources are provided along with RKit-STM8, so it should not be too difficult to modify.
However:
If you do not initialize glogal variables (NOINITSTATICVAR active for the compiler and no initialized globals), then the linker will detect it and will automatically configure your output project with NO STARTUP.
This means that main() is the actual reset handler in such a case. You can then manually initialize your globals within main.
Here is an example:
unsigned count; //unsigned count = 10; // NO! This will generate a data initialization startup. void main(void) { count = 10; // Initialize global variable manually ... //Whatever required }I hope this helps,
Bruno
Thank's a lot Bruno!
Ciao
