Resolved! There seem to be a mismatch in the STM32H747 documentation: The 176 pin version should have an VDDDSI pin, but it's missing in the pin definition and in the pinout. Is it a typo?

According to the STM32H747xI/G datasheet, the STM32H747IG has a VCAPDSI pin, but no VDDDSI pin at all.I'm sure i get something wrong here, because without VDDDSI pin, the VCAPDSI pin would be a miraculous source of energy! ;)But seriously: do i have ...

For what reason can UART RX interrupt freeze ?

Hi all,In the past, I've used HAL_UART_Transmit() with HAL_UART_Receive_IT() which freeze RX interrupt in case of RX interrupt while TX is still processing (see https://community.st.com/s/question/0D50X0000AhPrkRSQS/haluarttransmit-with-haluartreceiv...
