STM32L0x1 does not start below 3V

Question asked by thierry on Nov 6, 2014
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 ?
