Can FreeRTOS set gpio as wakeup source

[674943148]

Hi all,

i am using a imx7D board, and i wonder how to wake up the Cortex-M4 core after entering sleep mode. Is it possible to configure gpio as a wakeup source in FreeRTOS? How to do it?

Best regards

HI wang

I am afraid it is not possible as sleep mode supported only in linux.

Best regards

Hi igor

Thank you for your reply and there's something wrong with my statement. I used LPM_MCORE_SetPowerStatus() to enter LPM_M4_STATE_STOP in a FreeRTOS task, which is a low-power state with Cortex-M4 closed. But i don't know how to resume it with a tickless external interrupt. 

Best regards
