STM32N657 NUCLEO standalone ROM flash boot locks, but same FSBL works via GDB launch

Summary On a NUCLEO-N657X0-Q I have a custom (non-CubeMX-template) FSBL that copies an "LRUN" application image from external XSPI flash into AXISRAM and jumps to it. The byte-identical signed FSBL runs completely when I stage it with the debugger i

Hello,I am redesigning a circuit that uses the comparator LM2903YPT, because the previous circuit had an undefined output because of the inputs that were outside the common mode range.According to the datasheet the input common mode range for my appl

STM32MP1 + STPMIC1: PMIC intermittently enters an unresponsive state

Hello everyone,We’ve been dealing with a puzzling power management issue on our board (battery-powered design). The PMIC (STPMIC1) intermittently enters an unresponsive state that we believe matches the state described in AN5861. We’ve already implem

STM32H5 External interrupt is not triggering

Hello there!It would be really great if someone can look into this.I even tested it by reading the state of the pin and the MCU detected when the button was pressed, however when I set it up to use EXTI, its not detecting the interrupt. Could there b

HAL_TIM_OC_SetConfigChannel asserts on override_state

Hello, I am trying to setup TIM5 channel 1 to output a signal on its output pin. I generated the code using STM32CubeMX2. I am getting an assert failed during initialization.mx_system_init() calls mx_tim5_init() which calls HAL_TIM_OC_SetConfigC

STM32 MCUs Products

I am using TIM8 to generate a PWM waveform (a /wr signal to an LCD ST7789 controller) and the timer triggers DMA2 to load the next byte onto the PD8-PD15 bus. The 1st byte has to be loaded “manually”.It works, and the ARR CCR3 CCR4 values can be adju
