I opened an empty project to check the GNU ARM.
Finished building: ../main.c
Building target: LGL001_0.axf
Invoking: GNU ARM C Linker
arm-none-eabi-gcc -g3 -gdwarf-2 -mcpu=cortex-m4 -mthumb -T "LGL001_0.ld" -nostdlib -L"C:/SiliconLabs/SimplicityStudio/v4/developer/st
LGL001_0.ld:59: undefined symbol `__Vectors' referenced in expression
collect2.exe: error: ld returned 1 exit status
make: *** [LGL001_0.axf] Error 1
Solved! Go to Solution.

GCC support is in "beta" for the BLE 220.127.116.11 stack at this time. The logs that were posted showed it using the BLE 18.104.22.168 stack, if the empty project was actually created with the BLE 22.214.171.124 stack then there is an error in the project generation. If not please create the project using the BLE 126.96.36.199 stack.
The basic problem appears to be that the gcc startup code was not included in the project. In device folder (for example EFR32BG1B) under the CMSIS folder, a link to the appropriate startup_gcc_efr32 .s file should be included (for the example it is startup_gcc_efr32bg1b.s). It can be dragged from the appropriate location to the project folder and added as a linked file (example folder: C:\SiliconLabs\SimplicityStudio\v4\develop

I created a new demo projekt ( Thermometer ) and it's the first time I can compile and load in Studio.
Will see what hapens when I put my actuall files in.
