Primary UART is a compile-time option, you would need a custom firmware.

Ok thank you, those pins are RX PC10 and TX PC11 correct?

This depends on what FW you are using for your custom HW:
Code: Select all
$ grep EFI_CONSOLE_TX_BRAIN -R config/
config/boards/prometheus/efifeatures.h:#undef EFI_CONSOLE_TX_BRAIN_PIN
config/boards/prometheus/efifeatures.h:#define EFI_CONSOLE_TX_BRAIN_PIN Gpio::A0
config/boards/hellen/hellen-common144.mk:PRIMARY_COMMUNICATION_PORT_USART2=-DEFI_CONSOLE_TX_BRAIN_PIN=Gpio::D6 -DEFI_CONSOLE_RX_BRAIN_PIN=Gpio::D5 -DTS_PRIMARY_PORT=UARTD2 -DSTM32_UART_USE_USART2=1
config/boards/skeleton/efifeatures.h:#define EFI_CONSOLE_TX_BRAIN_PIN Gpio::C10
