Hi,
According to the following document, it looks like K210 has 16550
compatible UART for UART1/2/3.

This means that you can use nuttx/drivers/serial/uart_16550.c

K210 can only use UART0 at present. I would like to ask my friends, who has the
driver code for UART1-UART3? The current project needs to use it. It is too
difficult to transplant from the official code of K210.
