Created attachment 38436 [details] Test source code When building with AVR-GCC 6.1.0, -ffunction-sections and any optimization level other than -O0 then strings that are passed as a parameter to a function like puts("whatever") will be stored in flash instead of RAM. However, this will correctly store myString in RAM with -ffunction-sections: static const char myString[] = "whatever"; puts(myString); avr-gcc -mmcu=atmega328 -Wall -Wextra -O1 -ffunction-sections main.c
