Resolved! Timeout in RTC_INIT with HSE if an unused register does not have a unspecific entry is set!?

I have an STM32F446 with a HSE attached. Everything works fine (freeRTOS, CAN, I2C, ADC).Now I want to use the RTC but I cannot initialized it if I not set PeriphClkInitStruct.PLLI2SDivQ to an unspecific value. RTC_EnterInitMode() from the HAL librar...

Hello, I'm using STM32L4R5ZI with embOS OS( used released version) for my application. I've implemented boot-loader now for my application. I've set VTOR(SCB->VTOR ) as per my application flash start address and i relocate interrupt table to RAM.

STM32L4R5ZI has SRAM1 (0x20000000 - 0x2002FFFF) , SRAM2 (0x20030000 - 0x2003FFFF) and SRAM 3 (0x20040000 - 0x2009FFFF).I move VTOR table as per my Application Flash starting address. In code, I relocate Interrupt table to RAM for my own ISR handlers ...

Hi all, because just I have jumped to ST32 MCU, I would like ask you for help with follow general answer if its possible to do with this MCU. I have chosen MCU STM32G031G4.
