I would like to know how I can program 2 MCUs (stm32wb55cgu6) simultaneously.Currently, I am programming the FUS and BLE binaries (firmware developed by the company).We need to double production, but I can't program via DFU because an error always oc...

Resolved! Calibrating the STM32's real-time clock (RTC)

I have an STM32L011F4P6 with an RTC.  It is running at 3.3V and 16 MHz off the internal HSI RC clock.  The RTC is driven by a +/-20ppm 32.768 KHz crystal.  It is running at room temperature (23-25C).  After calibration, I am losing several seconds pe...

Resolved! HAL_UART_Init() assert with LPUART at high baudrate

I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...
