cuckoo clock problems

DDR1 clock problems, DDR1 clock Problems I encountered a problem recently. I had a hard time tossing for a week and had a special crash! When the board is powered on, when reading data from Flash, sometimes an error occurs when writing data to DDR. For occasional errors, it is difficult to use reveal to locate the err

function _ hal_rcc_hse_config (rcc_oscinitstruct-> hsestate) may be: rcc_hse_on, rcc_hse_bypass, or rcc_hse_off.If you use the stm32cubemx graphic configuration interface, you can see three options:In the Application Development of St MCU, active crystal oscillator is often used as the clock source. What kind of working mode should I choose if I use it?An active crystal oscillator is generally enclosed in four-pin packages, including power supply, gr
