STM32MP257F-DK USART6

[MasonPan0804]

Hi there,

I update the device tree of usart6 of STM32MP257F-DK as below but do not know if it was enabled during kernel.
Is it ttySTM0 or ttySTM1 or did not enable and how to check?

&usart6 {
pinctrl-names = "default", "idle", "sleep";
pinctrl-0 = <&usart6_pins_a>;
pinctrl-1 = <&usart6_idle_pins_a>;
pinctrl-2 = <&usart6_sleep_pins_a>;
uart-has-rtscts;
status = "okay";
}

You can use this page to verify that your UART is functioning correctly :
