Custom FW for DWM1001

Dear all.

I`m trying to use a custom FW for Decawave DWM1001 (FW from github GitHub - TIERS/dwm1001-uwb-firmware: Custom localization and calibration firmware for Decawave's DWM1001 Ultra-Wideband modules) with building the project with SES.

The building process always fail with “Linking ss_twr_init.elf”. The output panel said me:

Output/nrf52832_xxaa/Obj/ss_twr_init/main.o: in function `main':
undefined reference to `ss_initiator_task_function'

And clicking over second error, SES program show me the main.c file:

#ifdef USE_FREERTOS		
    /* Start FreeRTOS scheduler. */
    vTaskStartScheduler();	

    while(1) 
    {};
  #else

Does someone have an idea about this problem?

Thank you in advance.

Miguel.
