I've a STM32L451 uC with 1.8V of supply voltage.
I've the readout protection at level 1, but I can't go back to the 0 level. I tried with stlink and jlink ( j-link STM32 Unlock) but it doesn't work.
is there a sequence to solve the problem ?
The BOR is 0
Thank you so much

Thank you! I changed the supply voltage to 3.0V and it's work now.
