Overview

The sample initializes and starts an interactive shell, which can be terminated by using the “terminate” shell command.

Building and running

This sample can be found under samples/subsys/shell/bm_uarte in the Bare Metal folder structure. For details on how to create, configure, and program a sample, see Getting Started with the samples.

Testing

You can test this sample by performing the following steps:

1. Compile and program the application.

2. Observe that the bm-uarte:~$ prompt is printed.

3. Type help and press Enter.

4. Observe supported commands are printed.

5. Type terminate and press Enter.

6. Observe that the goodbye message is printed.

7. Observe that the bm-uarte:~$ prompt is printed again but the shell no longer responds to input.
