Hello,
I am a beginner in nRF. I want to implement EEPROM. So I am trying to execute Zephyr/sample/driver/EEPROM code but I am getting compilation error the below error message for board nrf52840dk_nrf52840.
In function 'get_eeprom_device':
/home/neeraj/Applications/Nordic/zephyr/include/device.h:81:39: error: '__device_dts_ord_DT_N_ALIAS_eeprom_0_ORD' undeclared (first use in this function)

I believe this error is because there is no eeprom_0 declaration in <board>.dts file. If this error is due to the same then what shall I declare in my nrf52840dk_nrf52840.overlay file?
Thanks in advance.
