Hi, I am working on STM32F107VC controller. When I tried to perform system software reset NVIC_SystemReset(), reset is not happening. When tried to debug, After NVIC reset, it is going to 0x1fffe71c location. The system is not getting reset.

That is in the bootloader. How is the BOOT0 pin set?

BOOT0 pin is not connected anywhere. It is left idle.

AN2586 section 3. Which binary level does a floating pin have?

[JK.4]

 

BOOT1 is not available. BOOT0 is left floating.

When power supply is given, at BOOT0 pin , a high pulse is observed with 1.6V, 5.4ms. The snapshot is attached.

Will it cause any bootloader issue?

Pull BOOT0 low to ensure it measures as VIL as the supply rises.​

Entering the loader suggests it sees VIH​

System Reset works fine now after pulling Boot0 pin lo low.

Thanks everyone for your help!!
