Hi, When I use the method under, to declare somme objets in the flash program memory, I can see the object in the .hex file whith AVR STUDIO 4.11 SP3, but it dont work whith the .elf file. Is that a bug of AVR STUDIO?
If I use PROGMEM of the pgmspace.h header that is all correct but the memory object is placed before program code. Can I put this anywhere?
