UART device names

I figured out UART0 at J21 is “/dev/ttyS0”, UART1 at J17 is “/dev/ttyTHS2”, what are device names for UART2 and UART3?

Thanks in advance.

hello yahoo2016,

please check the kernel function at below path for more details,


static int tegra_uart_probe(struct platform_device *pdev){...}

Thanks for the information,I’ll connect UART2 and UART3 on Dev Kit and try them.
