MCU selector misses Voltage reference buffer

Hello,looking for a STM32 in small package with pins where optical solder inspection is possible, I hoped that the MCU Selector from STCube would offer me a checkbox to select devices with Voltage reference buffer output. I did not find that checkou...

how dose the PC run to startup.s when the mcu reset

Hi,dear enginner:  i want to know how the PC run to startup.s when mcu reset?  The Definitive Guide to the ARM Cortex-M3 says address 0x00000000 is MSP‘,address 0x00000004 is ResetVector.  But when I look at STM32F767, I find that 0x00000000 and 0x4 ...

I am using STM32F401RB controller. Iam using external oscillator of 8MHz. The HSE and PLL mode is used. When i try to run the program, it hangs and no output. When I configure the internal oscillator it works fine. Please let me the solution for this.

I have called the three functions as: HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); HAL_GPIO_WritePin(GPIOC, GPIO_PIN_6, GPIO_PIN_SET);when debugging it either jumps to hard fault or hangs.The SystemClock_Config() is as follows:void Syste...
