zephyr RTOS task event creation

[Chandrasekaran J]

Hi team,

    we create basic task with event flag wait condition, but we got following error while try to build the application and it look like linker error. 

Event creation code:

    struct k_event my_event;

    k_event_init(&my_event);

Firmware details: nRF connect sdk V2.6.0
Board selection : nrf7002dk_nrf5340_cpuapp_ns

Here i attach the error statement for your reference

Hi,

Have you added CONFIG_EVENTS=y to you prj.conf?
