How to execute code from RAM on nRF51 using GCC Environment

[Håkon Alseth]

Hi,

You can place a function in RAM in GCC like this:

__attribute__((used, long_call, section(".data"))) void some_func(void)
{
  do_something();
}

Then you should check the .map file to see that it's located somewhere in RAM (0x2000XYZZ)

Cheers, Håkon

Hi Anand, It seems like there is some incompatibilities in SDK v6 with regards to placing functions in RAM (and calling flash-functions). I could not get this to work properly either. Could you try this on SDK v7.x or newer?
