Forcing const objects to be stored in program memory

See XC32 user guide sections “10.9.1 Const Type Qualifier” and “11.4 Variables in Program Memory” for full details.

Objects qualified only with const are not guaranteed to be located in program memory, some options can affect where const-qualified object are located.

To explicitly request that a const object is placed in program memory

Use the space(prog) attribute:

const char __attribute__((space(prog))) MyConstObjectName[] = {0x00,0x80,0x00,0x40,0x00};

extern const char __attribute__((space(prog))) MyConstObjectName[];
