Comment (by rmueller):

 I found the UART config in console-uart3.c

 {{{

 static const stm32h7_uart_config stm32h7_usart3_config = {
   .gpio = {
     .regs = GPIOB,
     .config = {
       .Pin = GPIO_PIN_9 | GPIO_PIN_10,
       .Mode = GPIO_MODE_AF_PP,
       .Pull = GPIO_NOPULL,
       .Speed = GPIO_SPEED_FREQ_LOW,
       .Alternate = GPIO_AF7_USART3
     }
   },
   .irq = USART3_IRQn,
   .device_index = 2
 };

 }}}

 and tried to replace it with this:


 {{{
 static const stm32h7_uart_config stm32h7_usart3_config = {
   .gpio = {
     .regs = GPIOD,
     .config = {
       .Pin = GPIO_PIN_8 | GPIO_PIN_9,
       .Mode = GPIO_MODE_AF_PP,
       .Pull = GPIO_NOPULL,
       .Speed = GPIO_SPEED_FREQ_LOW,
       .Alternate = GPIO_AF7_USART3
     }
   },
   .irq = USART3_IRQn,
   .device_index = 2
 };
 }}}

 Recompiled the BSP but it still is not working without the workaround from
 above. If I call printf, the function also never exits and something
 appears to be broken.. I don't really know why..
