Console over CDC ACM UART Sample¶
A simple Hello World sample, with console output coming via CDC ACM UART. Primarily intended to show the required config options.
This project requires a USB device controller driver.
Building and Running¶
This sample can be built for multiple boards, in this example we will build it for the reel_board board:
west build -b reel_board samples/subsys/usb/console 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”.

You may need to stop modemmanager via “sudo stop modemmanager”, if it is trying to access the device in the background.
