Hi,
I have compilation error to use SPI.
Checking project status
Building ‘ble_app_beacon_pca10056_s140’ from solution ‘ble_app_beacon_pca10056_s140’ in configuration ‘Release’

I have enabled NRFX_SPI_Enabled , SPI_SPI0_Enabled, NRFX_SPIM_Enabled and NRFX_SPIM0_Enabled.
Below is the details.
Here is portion of codes;

Please advise how to solve.
Thanks.
