Console and Shell over CDC ACM UART Sample

Overview

A simple Hello World sample, with console output coming via CDC ACM UART. a shell input is also coming via the same CDC ACM UART. Primarily intended to show the required config options.

Requirements

This project requires a USB device controller driver.

Building and Running

Make sure you have the CSK6 connected over Jlink debuger.

The sample can be built and flashed as follows:

west build -b csk6_xxx samples/boards/csk6/subsys/usb/cdc/console_shell
west flash

Plug the board into a host device, for sample, a PC running Linux OS. The board will be detected as a CDC_ACM serial device. To see the console output from the sample, use a command similar to “minicom -D /dev/ttyACM0”.
