LPC43S57 : Do not Wake up in Release mode ?

LPC43S57 enters in deep sleep mode, but when I toggle the wakeup0 pin, the software do not wake up ! (I have checked the HW signal and it move correctly from 0 to 1, or even from 1 to 0 but without effect)

Something strange is that the wake up occurs correctly if I load the "debug" version of my software (same code, but with configuration "debug" in MCUXpresso)

I also test a really similar software on the MCB4300 evaluation board (LPC4357 instead of LPC43S57), and the wake up occurs correctly in both "debug" and "release" configuration.


Do anyone have a clue about my problem ?
