setting DEBUG flag in eclipse

Hi,

Try setting the assembler also.

ASMFLAGS += -DDEBUG

The .elf /.out file contains a lot of extra non-executable data(meta-information, debugging information) that is not present in the .hex

So try using arm-none-eabi-addr2line with the .out file instead.

I am not getting into app_error_save_and_stop() and don't have an elf file, however was under the impression that a hex file is actually contained the elf data.

Unfortunately arm-none-eabi-addr2line doesn't appear to like my hex file, (it is the file I flash onto the board) I get the following:

/Users/venerly/nordic/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-addr2line 200516 -e nrf52832_xxaa.hex

which outputs:

??:0

Is the code going into app_error_save_and_stop() ?

If you have access the the PC, and you have the .elf file, you could use arm-none-eabi-addr2line to find where it is failing also.

// Example, pc=0x01BEEF

$ arm-none-eabi-addr2line 0x01BEEF -e app_beacon.elf

C:\folder\SDK\src\main.c:34

Unfortunately I am not seeing the expected behaviour. Despite implementing all of the above with the addition of adding app_error_weak.c to the makefile to ensure it is recompiled. I can see -DDEBUG applied to the compilation of app_error_weak.c in the build log.

However I am not hitting the expected line:

It has just occurred to me that I am using segger RTT which could be effecting the behaviour of NRF_LOG_FINAL_FLUSH()

Also Eclipse isn't alway honest when comes to highlighting.

So I have access to the PC, I guess I need to manually go through the map file to determine where things are failing?

Hi,

You should define DEBUG in the makefile. I.e. CFLAGS += -DDEBUG

You should also add the -g3 flag and remove compiler optimization (to get expected debug results). I.e. CFLAGS += -Wall -Werror -O0 -g3.
