SD132 NRF52 gcc debugging

Question

Hi I'm trying to port my firmware to the NRF52 DK, but I'm having trouble getting it to work. Could you give me a hint based on the stack trace below, what the problem might be? Thread #1

(Suspended : Signal : SIGTRAP:Trace/breakpoint trap) 0x20001248 () at 0xfffffff9 0xf5bbf576 0x1000000 I'm using SEGGER J-Link GDB Server V5.12g gcc 5.4 q2 Eclipse Mars Everything works fine for the NRF51 DK... This is driving me crazy.. Thanks for your hints in advance!

Agree with what @butch is saying. I can't make much sense of register values other than that there is some memory corruption. I suspect this can be related to either the startup files or that the "common" linker script is for the 51. 
 Your .ld settings seems correct, worst case with these settings is that you get a "no mem" assertion when enabling the stack if the RAM base is too low. It should not end up in a hardfault. 
 I would suggest to use try with the example/ble_app_template/s132/ example, and change the makefile so that it includes your source files, and see if it makes any difference. This should at least ensure that the startup and linker configurations are correct.
