Hello.
Can i read state of BOOT0 pin in STM32F030F4P6?
My uC always turn on with BOOT0 GND, but i need to have dual purpose pin BOOT0 and have possibility to read only state of this pin.

The datasheet marks BOOT0 as dedicated boot pin, so there is no way to do so.

See if you can use SYSCFG_CFGR1 to read the memory mapping at boot.

I just think that if i can set BOOT1 by software that is also possible to read BOOT0 throught some registers.
I check SYSCFG and it stays all 0 even if i pull up BOOT0 pin.
It looks that i have to short pin 1 (boot0) and 2 and then read state.

SYSCFG_CFGR1 shows the state of Boot0 at powerup, not at the moment of the query. That my be enough for your problem.

Unfortunately this isn't enough. I have to use GPIO and short them with BOOT0 pin.
Thank You for help.
