Posted on April 14, 2013 at 22:06 Hi everyone
I use STMF1 and STMF4 devices for some time now but I just started with STM32F0 devices (Discovery board) and I have a quite strange problem.
I created a class called Pin that can initialize any GPIO pin and use it (read, on, off, toggle, etc). When I create an instance of it like this :
Pin LED(GPIOC, GPIO_Pin_8);
everything is okay, but if I do this :
Pin* LED;
...
LED =
new
Pin(GPIOC, GPIO_Pin_8);
I have a flash memory overflow of 30492 bytes.
When I'm invoking the size command before and after creating an instance of Pin with the first method I have this :
Invoking: ARM Sourcery Mac OS X GNU Print Size
arm-none-eabi-size --format=berkeley base.elf
text data bss dec hex filename
4356 2132 1128 7616 1dc0 base.elf
Invoking: ARM Sourcery Mac OS X GNU Print Size
arm-none-eabi-size --format=berkeley base.elf
text data bss dec hex filename
4380 2132 1128 7640 1dd8 base.elf
Nothing extraordinary and I have still plenty of free space.
I'm using Eclipse with the GCC ARM toolchain on Mac OS X.
Does anyone have an idea about the origin of this problem?
