IAR and DFU problem

[Will_008700]

Hi 

I'd like to debug my code from IAR with nrf52840dk.

I'm using nrf5_SDK_thread_zigbee_v4.1.0.

I got this error after uploading the code inside the nf52840 dk

==>ELF/DWARF Error: Unsupported .debug_info format version: 4

I've checked the makefile, it's aligned with forum comment "-gdwarf-3"

If I remove "include debug information in output" in linker=>output, I can't debug the code, could you help me?

thanks

Hi,

The problem seems to come from the nrf_security/crypto libraries being built with the wrong debug symbol configuration. The simple solution to this is to strip the debug information from the lib-files. Normally there is no need to debug these libraries and the debug symbols can be stripped out. I verified that this works on my Win10 setup with a fresh copy of the SDK:

cd nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8\external\nrf_security\lib
arm-none-eabi-strip -g *.a

Best regards,
Jørgen

Magic, thanks!

I wish things just worked out of the box.. Started with IAR 8.x.x, that doesn't work, OK, then to 7.80.x which is supposed to work (Release notes), oops V_ARGS_ error..compile error. OK put brackets around double Macro calls with Macro args.. OK. then this "ELF/DWARF Error"... how many hours do we embedded developers waste on getting the setup right?!
 
I still appreciate Noridc's team support but it would be nice if things "work out-the-box"

Thanks!
