Warning: attempt to assign the value ' y' to the undefined symbol NFCT_PINS_AS_GPIOS

Hi, 

I'm trying to set NFC pins as GPIO in my custom project. I'm using zephyr 1.8.0 SDK. I added the following line to my prj.conf:

CONFIG_NFCT_PINS_AS_GPIOS = y

When I compile the project, I get the following error: 

warning: attempt to assign the value ' y' to the undefined symbol NFCT_PINS_AS_GPIOS

What can be the issue?

Thank you!

Hi Emile, 

Please avoid using space in the configuration. Please try: 

CONFIG_NFCT_PINS_AS_GPIOS=y 

No space near '='

Good, that was the problem! Thank you!
