On the L4R5 and on the U575 when the LPUART uses the LSE clock source (32768Hz) and is configured for 9600 baud the byte timing is very precise, exactly as predicted by the reference manual as (RM0432, 51.4.7). However the timing of individual bits w...

This isn't a question - I just spent a LONG time finding this so I figured I'd post my solution in case anyone else runs into it.The STM32U5 seems largely backward compatible with STM32L4 source code, but in order to have certain low power peripheral...

In AN2606 it says:"For STM32 devices having the Dual Bank Boot feature, to jump to system memory from user code the user has first to remap the System Memory bootloader at address 0x00000000 using SYSCFG register (except for STM32F7 Series), then jum...
