High level at the outputs of PA9 and PA10 after reset. STM32G030K8

After resetting, the output of PA9 and PA10 of the STM32G030K8 microcontroller is high. These pins are not initialized, according to the datasheet after reset they should have the function of an analog input. Once configured, they function normally a...

STM32H745 FMC acces to external NOR with timing from RM0399 does not work (works only with burst, but not non-burst)

Hallo,I'm using a STM32H745, that shall access an external NOR flash with the timing recommended by ST at the reference manual RM0399 on page 875.  I did exactly reproduce this timing setting, but no access will be generated on the FMC pins.When I ch...
