Hello,first of I must state that this is a bare metal project. If bare metal is not your thing then please do not read on. I only use parts of the CMSIS but no HAL and no LL.I have a strange effect when using I2C1 bus with DMA and USART1 with receive...
Hello,I am having a strage problem with setting up simple input pins on PB3, PB4, PB5, PB6 and PB7 with pullup on a G441 bare metal. I set the bits in the GPIOB_MODER and GPIOB_PUPDR acordingly and also read them back to make sure. They are correct. ...

In the reference manual RM440 Rev7 that register is missing while the register is defined in the SAI_TypeDef. I only found a description in the F446 RM0390. Are they the same?
