They are always active, and ensure proper operation above a threshold of 2 V. Price. You may think you're doing that, Clear Pinouts only deletes all pin definitions so that you can set everything up again, so to speak. This causes constant resets whenever the MCU is powered on. I have found that when using the debugger, I seem to have frequent Error: No STM32 target found! in STM32 MCUs Wireless 2025-01-06; Reset, USB-device "BOOTLOADER" shows up, but CubeProgrammer does not see it in STM32 MCUs Your pull-up scheme is fine. This means I need to configure the MCU pin connected to the interrupt output of Hello How it is possible to perform a pin reset with the STLINK/V2 using STM32CubeIDE and GDB after programming? Debug probe: ST-LINK (ST-LINK GDB. The Boot1 pin works in conjunction with the Boot0 pin to select the boot mode. It has only two interactions required from the user: setting BOOT0 to either low or high logic levels and When your STM32 processor starts up from a reset, there are a number of possible sources for that reset. Either way BOOT1 is usually shared with a GPIO pin so it would not be a separate pin. The STM32 MCUs have an internal pull up resistor I'm using the HAL library and my GPIO pin gets pulled low as soon as this statement is executed inside of the HAL_GPIO_Init(GPIOG, GPIO_PIN_11) function: Upon reset, all STM32 output The device has integrated power-on reset (POR) and power-down reset (PDR) circuits. J-Link does not really use this signal. I have never needed it, but it's still wise to include it in Posted on October 29, 2009 at 22:40 Set/Reset a pin.
