Hello Priya,
- Under the KSDK1.2 installation directory , there is a even demo , have you test it , does it can work well on your side :
...\Freescale\KSDK_1.2.0\rtos\mqx\mqx\examples\event
- And where do you create the event ? Please pay attention that , the task which create the event must prior to the task which use the event .
Hope it helps
Alice
