Resolved! SPI dma reads start at index 1 after first read

I'm trying to read and write SPI bytes from an STM32F446RE chip with DMA.  The STM32f4 is the slave and a RPi is the master.  The first SPI read works fine (data read into buffer starting at index 0), but subsequent reads have the data starting at in...

Resolved! stm32g030 RTC/LSI ticks 50% too often

Hi!I use the RTC of a STM32G030K6T. It is clocked by LSI (appr. 32kHz). And PREDIV_A is 0x0 and PREDIV_S is 0x7FFF. So I expect that RTC_SSR overflows every 1.024sec...But: It overflows every 0.687sec... As if the LSI frequency would be 47712Hz...I m...
