Has anyone encountered this problem? An ORE error occurs when receiving data with LPUART. After I clear it with software, an ORE error occurs every time I receive data. How can I solve it?

I want to let STM32L552CC into sleep mode.I add HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI);Build is OK,but when Debug ,the error appeared, Why?

When debugging, I saved the data in flash memory successfully and at soon the HardFault_Handler happened ,way? I used the same function in examples and the same Flash memory address. https://github.com/STMicroelectronics/STM32CubeL5/tree/a7a8ea66c42c...

I solved it. The general set is wrong. Must set 8 bits not 4bits or 2bits

Thank you. I solved it。BOOT0 pin must be set Low。I opened it。:face_with_tears_of_joy: it

The question about Sleep mode

STM32 L522C . I want to get chip to sleep mode and wake it up by time interrupt of 32KHz clock . How do I?

Re: Why the number of data I sent is wrong when using HAL_SPI_TransmitReceive()　 ?

Re: The code I wrote on the board Nucleo-L522ZE-Q has time interruption and controls the LED to flash. It is successful. After being applied to my own circuit board by ST-LINK , the time interruption cannot occur. I want to know why?
