Hi Rushikesh,
The ttyS0 is the console serial port.
Try to study about Linux to understand these concepts.

Hi,
I have run sample serial examples like* serialblaster*, *serialrx* but I
have one doubt is that, when we give devpath as* /dev/ttyS0* , we are able
to connect and communicate with the nsh console.
Is it really a* uart/usart communication* happening or are we just using
virtual com port to com
You need to enable: USARTx peripheral, setup your Driver -> Serial to
correct baudrate, etc and then you can run the serialrx example.
BUT you need to setup CONFIG_EXAMPLES_SERIALRX_DEVPATH to the right
port, i.e.: /dev/ttyS1
Before mastering NuttX it is important that you know Linux, otherwise

Hi Alan Sir,
Thanks for your reply.
The serial driver already exists for STM32H7. Are we willing to
exchange data over serial port?
-> Yes sir. I want to transmit and receive data using uart.
Just do the same thing you do on Linux: open(), tcflush(), tcsetatt
-> these functions we have to use wh
Hi Rushikesh,

You need to use /dev/ttyS1..N the /dev/ttyACM0 is for USB/Serial example.

Hi,
I am trying to create my own uart serial driver which includes transmit and
receive data .
For that i was trying to understand a sample example which is given
already. For this example given file are mentioned below,
In nuttx folder,
1. nuttx/drivers/serial.c
2. nuttx/include/nuttx/serial/se
