STM32U5 lower power mode in Threadx with trustzone enabled

[Gautham19]

Hi Team, I'm currently trying to enter low power mode mode stop 0,1,2,3 and standby mode with Trustzone enabled using Threadx. The device is entering low power mode when interrupt triggers the thread is not resuming it still in the low power mode. Is there any material to proceed low power mode in trustzone enabled in Threadx.

Hi @Gautham19 

You can find attached an example with TrustZone and low power enabled with ThreadX.

It doesn't seem to show any particular issue. Would you please share more details about the issue you are facing exactly, and share some code snippets to understand the problem ?
