Resolved! Fails to execute from QSPI Flash but read works

Hi,I have some issues with executing directly from QSPI with a NUCLEO-F412ZG and a connected Winbond W25Q80DV QuadSPI Flash which we are looking into as a workaround for the component shortage (will be a L4 variant but using a F4 for testing).Reading...

HSE oscillator when using USB

The STM32F303xB datasheet states that HSE oscillator should be used when using USB. I suspect it is because of the degraded accuracy of the HSI oscillator at temperature. I've had issues with CAN not working well with HSI at elevated temperature. Doe...
