nRF58122 GCC S120 Softdevice Build failure - Collect2.exe

[mtsunstrum]

I am experiencing an error in the final linking stage of my build.

_build/blinky_gcc_xxaa_s120_xxaa.bin: file not recognized: File format not recognized collect2.exe: error: ld returned 1 exit status make: *** [debug] Error 1 (See attached buildlog.txt file for full log output)

I can't understand what this error concerns. I see the file [_build/blinky_gcc_xxaa_s120_xxaa.bin] exists

I am attempting to build a copy of the experimental S120 app found in nrf51822\Board\nrf6310\s120\experimental\ble_app_multilink_central but having it run on a pca10001 Evaluation Kit, using GCC.

I have experience this on both SDK 5.1, and the newest SDK 5.2

Any help/thoughts are appreciated.

Regards, Martin

I haven't solved this issue, but some extra observations:

The problem is the last nonsensical gcc operation ...

I noticed if I do "make release", then my build is fine. If I do "make debug", then I get this last rogue gcc operation.

Notably, if I continue to run my application with the .out file, it runs fine.

It appears to be a makefile build rule causing this last gcc operation.

After playing with it for a while, I was not able to solve it. Maybe someone else will stumble upon this, and see the same issue. I have included the various app Makefile, and gcc Makefile/Makefile.windows for analysis.

To work around the issue, I moved over to using the pure-gcc Makefile operations, and everything works very fine now. Builds cleaner, faster and easier to understand.

Thx.
