Hi, My problem is same as you Ben, I remove the directory which named nRF_micro_ecc and add the micro_ecc_lib_nrf52.a through Option->Linker->Library.

I guess maybe the IAR can not debug with *.a file in the project.

I had the same problem using:

IAR 7.20.2
gcc 4.9 2015q3 (to compile micro-ecc)
SDK12.1.0

Using the -gdwarf-3 and -gdwarf-2 options in the micro-rcc Makefile did not help. But the remark about not generating debug information did give me a clue. I removed the -g3 option from the micro-ecc Makefile and it compiles/loads in IAR without problems. The advantage is that I still have debug information from the dfu software itself. Only the micro-ecc part is without debug indormation.

@max, we have managed to reproduce this with IAR v.7.80.4, and have reported this to IAR. A workaround that was suggested was to disable the "Include debug information in output" option in Project > Options > Linker > Output. Unfortunately, debugging gets quite limited with this disabled. An alternative is to use the Segger Ozone debugger together with the output file from IAR. Just make sure that the "generate debug information" option in Project > Options > C/C++ Compiler > Output is enabled.

Try with the -gdwarf-2 flag.

Hi max, you need to compile the ECC lib with -gdwarf-3 flag. Put it into the ecc makefile.

my IAR 7.8.2 maybe it is a problem?

We tried here with SDK 12.2.0, PCA10040, IAR 7.50.3 but it worked fine. Would it be similar bug to this ?

@All: Please try to add -gdwarf-3 to the list of compiler flags and let me know if it fixes the issue.

I have the same problem on DFU_secure _debug in sdk 12.2.0

Do you use IAR and GCC together?

I have same error appears when debugging the ble_app_multirole_lesc example in SDK 12.2.0 from IAR. Can you update the question status?

I think I got it. I had to add a flag in the makefile: -gdwarf-2
