Does exists some examples?
I have problem with suspended A53 - M7 core stucks too. Only freeze state in linux keeps M7 running.

Hi @msv_zitnik!
Sorry for the delay.
The MCUXpresso has a demo that might help you: the low_power_wakeword. Please follow the article Setting Up MCUXpresso SDK and Toolchain for Cortex-M development | Toradex Developer Center to download it.
