softdevice_enable: NRF_ERROR_NO_MEM, 0x4

Question

I'm trying to make the nRF51422xxAC advertise. Using Segger Embedded Studio. 
 I have this code: bpaste.net/.../f29f74986c10 
 On line 109, I have a breakpoint. At that point in the code, err_code = 4 , and after that, the nRF resets. 
 #define NRF_ERROR_NO_MEM (NRF_ERROR_BASE_NUM + 4)
 No Memory for operation. 
 
 I have tried with different SRAM_START in the Linker settings: from 0x20001FE8 up to 0x20007000 . The chip should have 0x8000 bytes of memory if I read correctly. Anyway - I get the same behaviour every attempt. 
 I have looked at other forum posts but haven't found anything directly applicable. Line 105 is from trying one of the solutions to no avail. 
 From the softdevice_enable documentation: 
 
 If the app_ram_base is too low, this
function will return an error. Using a
app_ram_base that is too high will not
fail, but will result in RAM that is
never used 
 
 But I can't find any further information on how much memory is needed. However, I would be surprised if a bigger SRAM_START than 0x20007000 is needed... The problem is probably something else.

Hi Erlend, 
 Have you tried to search similar questions about ble_stack_init(...) function on this forum? I'd recommend this one as an example. It solves your problem for GCC but I hope that SES will have very similar construct for any SoftDevice S13x V2 or newer (just find equivalent of __data_start__ external variable if it isn't the same). Not sure if SRAM_START is equivalent of RAM memory segment in GCC linker script (LD file), that would explain the failure as well. 
 Cheers Jan
