More macro hell from Nordic.

These macros are required in

<sdk-15>/modules/nrfx/hal/nrf_spim.h

lines 177-85.

They are likely supposed to be defined in your sdk_config.h or, now new in sdk-15, some other generated header include.

While sorting the issue,I am getting a new error:  #136: struct "<unnamed>" has no field "CSNPOL".

Can you please guide me to solve this(I am a beginner in this field.So kindly help me in solving this issue).

Thanks.

I think the SPI driver in SDKv14 did not support the hardware CSN pin that is configurable on the nRF52840, instead the CSN pin had to be controlled by the application before and after each SPI transfer manually.

If you need the new functionality you will need to do quite some changes, because there were quite some changes to the drivers going from SDKv14 to v15 as described here:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/migration.html?cp=4_0_1_1_9_4#migration_drivers 

Go down to 'Drivers' if you are not automatically taken there.

I have gone through the above link.But I don't know any basic idea about how to do the required changes.

Can you please guide me to solve this.
