LPC54608 Deep Sleep Mode exit

santosh1 — Mon, 14 Oct 2019 19:18:16 GMT

Hello,

I am attempting to verify LPC54608 power management with OM13092 dev board. The case i am trying to verify is exiting Deep Sleep Mode using pin interrupt (SW5 on OM13092). I am able to exit Sleep Mode with SW5, but unable to exist Deep Sleep Mode with SW5.

Starting point for the code is the power_manager demo app in 54608 SDK. I made a few changes to support the LEDs on the OM13092 board. Other than that the code has not been modified.

From what i understand in the documentation, Pin Interrupts should cause exit from deep sleep modes, is that correct? If it is what could prevent the exit?

I have attached the modified power_manager_lpc.c file.

Thanks

Hello Santosh,

Can you please briefly describe how you are getting stuck in deep sleep mode (in what part of your code are you not able to wake up)? Have you ran the example successfully prior to making the modifications?

Please let me know so I can help you find the root cause.

Best Regards,

Sabina
