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,

I tested with SDK v7 , Still I am facing the same issue as below. (.data+0x1a): relocation truncated to fit: R_ARM_THM_CALL against symbol `simple_uart_putstring' defined in .text.simple_uart_putstring section in _build/simple_uart.o

Can you please check this on higher priority.

Regards, Anand
