Debugging your device

Your device should be configured to always download the latest Target version with a specific tag.

By default, devices will run all applications that are defined in the containers.git repository and therefore available in the latest Target. This behavior can be changed by enabling only specific applications. We will cover this in more detail a little later.

To check your device configuration, you can click on the tab devices on your Factory and find the column TAGS:

You can also use fioctl to read information about your device.

fioctl device show <device-name>

Example Output:

As expected, the device is configured to follow the devel tag. Based on that, it found and updated to the latest Target with the devel tag, which is version 4. Because you didn’t specify what application it should run, it automatically loads all applications available in the current Target. In this case, shellhttpd.

Another way to verify applications running on the device is with the docker ps command:

docker ps
