...access memory segments from within a program

How can I determine the start and end addresses of a memory segment from within a program?

 

The CrossWorks for ARM linker script generator creates __segment_name_segment_start__ and __segment_name_segment_end__ symbols to mark the start and end of each segment.

As an example, if you want to set a pointer to the start address of the FLASH segment you could use the following code:

extern unsigned char __FLASH_segment_start__;

void
func(void)
{
  unsigned char *ptr = &__FLASH_segment_start__;
  ...
}
