which USART can I use for bootloader?

[NZube.1]

I can see in the datasheet of STM32G474CE that I can use USART for reprogramming the Flash memory, but I am trying to understand which one?

In STM32F4 I can use USART1 and USART2, is it the same here?

Thanks.

What does App Note AN2606 say for your part?

[TDK]

USART1, USART2 and USART3 are available. The details are in AN2606.
