It does not look like the files in your second case differs from the files you posted in this case. Did you mean to upload the same files? Could you explain in writing what your problem is?

I just opened another thread about the debuging issue: devzone.nordicsemi.com/.../ Please check the joined files for details about the issue. Thanks a lot

Unfortunately, this is the only tutorial we have on Eclipse and GCC. You might find some other tutorials by searhing the web. What exactly is the problem when you try to debug?

The problem stills there, if you have any links to a good tutorial on how to setup the debgging on eclipse it would be great (I already followed this one: devzone.nordicsemi.com/.../ without any result) thanks a lot

Could you try adding the debug flag to assembler flags in your Makefile? ASMFLAGS += -g3. It can look like you are facing a hardfault from one of your images (() at 0xfffffff9). I guess this might have been solved now, though.

Thanks, that solved the problem, but eclipse debuging still does not work

Are you not able to flash the softdevice? It sounds like your application is placed in the softdevice region. From your original question you wrote "I also changed the linker file to the toolchain default "nrf51_xxaa.ld" file." Did you change the linker file RAM and FLASH settings to make room for the softdevice? You should rather use the linker file in the project directory, and adjust the size depending on your chip. AA chip have 16kB RAM and 256kB FLASH. Your settings should then be (ble_app_uart_c example in SDK 12.2 for S130 v2.0.1):

FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
RAM (rwx) :  ORIGIN = 0x20001eb0, LENGTH = 0x2150

See this tutorial about RAM and ROM management (it's a bit outdated, but the basics still apply).

I just tried that, but the breakpoints could not be set on "NVIC_SystemReset" it seems unresolved or the debugger can't find it

Ok I am doing this. Please note that loading the softdevice before the application always returns errors while loading the application ("you are trying to flash a softdevice region"), I tried with both S130 V 1.0.0 and V 2.0.1

Could you check the return code from the failing softdevice call, by debugging as described in this answer?

Debuging with Keil gave me this, once the code reaches:

err_code = sd_softdevice_enable(p_clock_lf_cfg, softdevice_fault_handler);

The Dummy Exception Handler is launched:

            SVC_Handler     PROC

                                    EXPORT  SVC_Handler               [WEAK]

                                    B       .

                                    ENDP

I guess this means a problem with the softdevice, any ideas ?

I just changed the softdevice clock to NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, but still have the same issues

No my board does not have that crystal

Does you custom board have the 32khz RTC crystal ?

I am using the latest gcc (6.2.1), I didn't set any option since I kept everything as it was from SDK 12.2.0 examples. Anyway I tried what you said and it still not working. Thanks

Have you tried to compile without -fno-builtin in your makefile? Don't know which version of armgcc you are using (gcc 4.8.x had a bug), thus I had some issues where I could not use the debugger while this option was enabled. Maybe you give it a try. And I saw that you set D__HEAP_SIZE=0 to 0. Are you sure your program is not using any heap space at all?
