I am trying to enable secure boot in stm32L562ve and I enabled the secure boot via cube programmer(Option bytes - TZEN) with no application in flash memory. And now I can't connect the board.... how to disable trust zone in stm32L5 series?

Hello jk.1

To deactivate trust zone, you need to perform a regression from RDP Level 1 to RDP Level 0 then do a power cycle.

Hope you find this helpful
