can't debug in source code

[william]

I have worked on a new project which would convert our NRF51 project into NRF52. I have succeed in compiling and linking code for this new NRF52 project. When I start debugging, I found I only can debugged in assembly code view and can't set breakpoint in source code. It will display "no code for breakpoint".

I backed to try NRF51 project, I did not see this issue. I have also tried the NRF52 examples and they all worked fine and can set breakpoint in source code.

Can you point me which direction I should look for to resolve this issue? I am current working on NRF52 SDK13.0.1 with GCC 4.2.1.

You didn't provide much info. I am guessing that you forgot to change processor settings.
The nRF51 is a Cortex-M0. The nRF52 is a Cortex-M4F. Make sure your compiler settings are for the right processor. Don't forget to replace the startup code and linker script as well.

I have compiled and linked properly with NRF52 setting. I also can debug it using NR52 DK board in assembly view mode. It's just I can't set debug point in source code which is very inconvenient. I did not found any related issue base on your suggestions.

Could you give details of your build environment?

You mention GCC, however you have not said whether you are using an IDE or simply using GDB on the command line

I am sorry for I did not give out the complete information at the first time. I am using Cross Studio 3.7.5. I can this cross studio to load in example of SDK13.0.1 and make it compiling and debugging properly. I just got stuck with this debug issue. Thanks!

I am not familiar with CrossWorks. What I can suggest is to create a new project then import the source code.
