Transferring the project to nRF52811 hardware - FPU error

Hello,
I am using the PCA10056 to program a nrf52811 chip on a custom board with SDK 15.3.0.
I'm using the example ble_app_blinky_pca10056_s140
I am following the steps in Infocenter infocenter.nordicsemi

Although I'm having questions on 2 points

1. I get a compilation error "#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)""
in 
#elif defined ( __GNUC__ )
  #if defined (__VFP_FP__) && !defined(__SOFTFP__)
    #if (__FPU_PRESENT == 1U)
      #define __FPU_USED 1U
  #else
    #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"
    #define __FPU_USED 0U

I checked and __FPU_PRESENT is set to 1

2. On step 6 in the documentation I can't find the files to delete, _startup_nrf52.s and system_nrf52.c


I would really appreciate if I can get some help
