winavr pragma

Hi,

Does anyone know pragma's definitions for WinAVR gcc compiler??
I need to controll memory areas where the compiler can access, and I know that with #pragma I can to define to copiler this area, but I don't know the parámeter.

Thanks for all.

Best Regards

avr gcc pragma

WinAVR does'nt use #pragma

But .sections

Basically read up on the GNU linker scripts.

Or maybe go to the AVR GCC forum on AvrFreaks
https://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewforum&f=2

And USE the search function there

Thanks I've seen it!!!!

The only problem is I need to change the linker parameters to move memory sections. I thought that was possible to create a new memory section (defined by me) and put it in a specific memory location in run-time (inside C code)

The only solution that I found is create my dinamic variables with mallocs (are saved in HEAP section) and modify in linker options the location of HEAP in external SRAM.

Best Regards!
