Can't get Eclipse debugging to work for nrf52

eq

Hello,

We are switching chips from the nrf51 to the nrf52832. I have a nrf52-DK board now. My Eclipse set up is still able to compile, run, and debug my nrf51 projects, however, for the new board I cannot debug. The code compiles fine and I can Flash successfully but when I try to debug I get no source available for 0x0 or other random addresses like: No source available for "0x14b05e0".

I have been thru all of the tutorials regarding how to configure debugging (again it works fine for the nrf51 chips). I have selected device nRF2832_xxAA under Settings/Devices, but it still won't debug. Below is the latest console log. Any insight would be greatly appreciated. Thank you!

    @Sigurd - Yes all of the Build Configurations options are Exactly the same as the previous projects that are working. The only difference is that the other projects are running on nrf51. The new project is running nrf52. Also I am running on Windows 7 which seems to be slightly different from the post that you shared.

    @Butch Yes Butch, compiler flags below:

    CFLAGS += -Wall -Werror -O0 -g3

    I have also tried just:

    CFLAGS += -Wall -Werror -g3 (which doesn't work either)

    I have made no mods to the Linker Flags. As a Makefile Template, I am using the one from SDK 12.2 ble_app_hrs. Soft Device S132; Board PCA10040. I only modified it to add my additional source files.

    The answer to your other question is "THE DEBUGGER SEEMS CONFUSED"...no source available for 0x0 is displayed most of the time. The debugger is not running in an executable region.
