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 Håkon,

To give you a more information. Please find below versions of the software and hardware I am using.

Soft device :s110_nrf51822_7.0.0_softdevice SDK : 6.1 Hardware : N51822 QFACA1 1442AB (version 3.1 -32 KB RAM variant).

Can you suggest me which files and what changes are needed to come out of the above error.

Regards, Anand
