I'm using STM32F0 Discovery and need to store values in SRAM when MCU is powered off.
I already removed SB1 shunt. Then VBAT is not powered from VDD but pin3 of P1 (VBAT pin supplied with 3V).
When I turn off my STM23f0 device and turn on again the values are not stored.
It is possible to do this in this device?
If it is possible, someone can help me?
