Our design is operating properly on 3.1V PSU.
When we try to start it with 2.9V PSU, it does not start.If we boot at 3.1 V and then reduce the voltage to 2.9V, it stops.The Brownout Reset (BOR) is set to 'disabled' and there is no IRQ activated on PVD.BOOT0 is properly connected to GND via 0 ohm resistor.The clock is 32MHz.Has anybody a clue what is causing the STM32L0x1 not to work at 2.9V ?
