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:https://wiki.segger.com/index.php?title=J-Link_can%27t_connect_to_the_CPU: "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?
