After deep sleep, using the io port to wake up will cause stack overflow（JN-AN-1246）

[Tome-mbedded]

hello @nxp1

I used the JN-AN-1246 project to compile the LTOSensor. When the sensor cannot join the network, it goes into deep sleep. So I enabled the DEEP_SLEEP_ENABLE macro. When I used the io port to wake up the sensor, it did not work properly and appeared

Hard Fault Handler and Stack Register Dump. What is the reason for this?

Attached is the print log

Hello @Tome-mbedded

How are you modifying the base source code? Have you only defined DEEP_SLEEP_ENABLE macro in your code or did you add any other modification? In case you have added any other modification to the base source code, could you share it so I can try to test it on my side?

Could you please provide more details on the process you have followed to test the application?

Regards,
Eduardo.
