STM32WL Shutdown mode

[onass]

I am experiencing difficulty getting the NUCLEO-WL55JC1 to properly enter Shutdown mode.

In some cases, the device appears to enter Shutdown mode but exits immediately. In other cases, it remains in Shutdown mode, but the current consumption is approximately 1 mA.

The procedure I am using to enter Shutdown mode is straightforward, yet the behavior does not seem correct.

Could you please advise on possible causes or recommended debugging steps for this issue?

Hello @Imen.D 

Thanks for your reply,

My problem was that I did not disable debug in low power modes option in the debug configuration,

Once debug was disabled in low power modes, everything worked perfectly
