Hi Savinay,

Are you trying to run the code with "lowpower" demo under MQX folder? Which MQX version you use? Are you running this with Freescale tower board or with your own board? If you are running with your own board, did you port the BSP?

If you have written your own low power entry code, then please share your code.

Hi Hao,

We are using our own board. BSP is ported to this board. We are using lpm api provided by BSP to enter low power mode.
