Hi, I am working on ST STM32L151VB-A, I burned a loader which already worked for me, and since then I get ''active write protected STM32 device detected'' also on other application that worked fine.
when I try to connect via J-Link commander I get ''cannot connect to target''.
as I understand from:
''This can have different reasons as for example the application does disable the debug interface, re-configures the debug pins, enters some kind of low-power-mode or the security of the device is activated. In order to prevent such situations during the development process''
is this reversible at all? What can be done?
Thank you!

Hi,
If pin BOOT0 is not directly connected to GND you can connect it to VCC in order to change the boot mode (see reference manual).
