Hello all,
I'm currently developing a project with a lot of constant strings (for a multi languages user interface) on NXP1768 , LPCXpresso V8.1.4
example of string definition:
// Define language id.
static const char * lang_text[10]= {"EN","FR","NL","IT","TK","DE","SP","PT","??","??"};
When the project is compiled in Release mode, strings declared as static const, are store in flash memory.
When I try to compile in debug mode, looks like a copy of these "static const" is made in RAM and therefore RAM usage goes from 15% (Release) to close 98%(Debug).
I guess this is for the debug probe to access these data...
Memory region Used Size Region Size %age Used
MFlash512: 223092 B 512 KB 42.55%
RamLoc32: 32132 B 32 KB 98.06%
RamAHB32: 0 GB 32 KB 0.00%
I still need to complete the project and will soon face a RAM issue in Debug.
Is there a way (compiler option...) to tweak the Debug version so that these data are not copied into RAM ?
Thanks
René
