MCU does not boot on power up, only boots when reset button is pressed (STM32F407VG)
Hi all,
I have a new design which is actually the second version, and this problem was not exist in the older version.
I'm using an STM32F407GVT6(datasheet) MCU with most of the peripherals that can be used including SPI, I2C, RS232, USART ect.
The problem is when I plug the circuit, I does not boot automatically, yet when I press the reset button, it boots.
I checked all the voltage levels, they are fine. I pulled down BOOT0 pin and pulled up BOOT1 (although BOOT1 is don't care when BOOT0 is 0).
The main difference between my previous version and this version is the power stage, but I'm not sure if such a problem can occur due to a mistake in the power stage.
If anyone can give me any clue of why such a problem can be occured, I can focus on it and solve the problem.
I can give more details if needed, any help is appreciated.
Thanks,
Ogulcan
