I'm using an STM32G473 on a custom board. The board is connected to battery pack and once assembled the MCU is permanently connected to 3V3. We're using STANDBY to put the MCU in a low power consumption state while the system is turned off.
My problem is, it does not seem possible to place the MCU in STANDBY after debugging without performing a power cycle. We have a physical reset button on the board but this doesn't seem to change the behavior.
I read a post by @Tesla DeLorean that alluded to some security features of newer STM32 MCU's that would explain this behavior. Does anyone have any idea of a workaround to this? We need to be able to debug these boards after assembly.
Thanks for your help in advance
