Can't post screenshots.RM0401 rev3 ('F410), RCC_APB2ENR contains EXTIEN. There is no such bit in any other STM32, EXTI is unconditionally enabled everywhere else. There is no respective reset bit in RCC_APB2RSTR. Is this bit real?in the same RM0401 r...

What other peripherals are enabled?Note, that if you use blue pill, it is very unlikely that it's a genuine ST part.JW

If you decided that it's better to avoid using RTC entirely, then the best way is, upon startup perform a backup-domain reset (see description of RCC_BDCR.BDRST - note that PWR.) and then avoid setting up and using RTC entirely.JWPS. Yes I've seen yo...

Unless the 'U5 has a vastly different SPI as compared to other STM32, as others said above, there's no DDR-style SPI.As a workaround, you could use SPI as a slave, generating clock by a timer, one channel set to PWM and other to Toggle; feeding the f...

> will it reduce the probability if I change the LSE to always turn it off?How do you mean that? If you turn off LSE, RTC will not work.JW
