Hi All,
I’m looking for an userspace ‘C’ test code to transfer a file on UART Tx line and receive the file on UART Rx line to test loopback supported serial port.
Before sending file on UART . I would suggest you to test sending simple buffer and ensure you receive it correctly.
Can anybody give example of such application?
I am assuming you have correct hardware ,ensure RS-232 RX-TX lines are short.If you are not sure follow below link [image: image.png] Coming to application which tests loop back,there are plenty tools like 1.minicom 2.cutecom etc. if you want to specific application try below https://elinux.org/images/b/b7/Uart-loopback.c https://medium.com/@amitasinghchauhan/serial-port-debugging-101-loopback-tes...
