Hello,

I am designing a custom PCB using STM32F405RG mcu. I have some doubts regarding BOOT pins and RESET pin. I am trying to follow schematic of STM32F4 discovery board and Olimex STM32F4 board. Discovery board schematic shows RESET pin connected to a 100nF capacitor and ground while Olimex board shows RESET pin connected tp ground via 1K resistor. BOOT0 pin in discovey is pulled down using voltage divider in discovery while olimex uses 4.7K to ground. 

I want to know what configuration of resistor and capacitor should be used for BOOT0 and RESET pins
