Troubleshooting
Here we describe various issues with Vadelma and how to work around them.
Attach a HDMI cable and a regular keyboard to the device. When you see a console prompt, type username root and press Enter. No password is needed.
The experimental audio driver reduces to background noise on newer Raspberry Pi devices. More info and how to enable it is found on this blog post. Remember to first boot Vadelma once with an analog speaker or head phones connected. Once you hear sound you can power off the device and add the audio_pwm_mode=2 line in the config.txt file.
Vadelma is not designed to detect removable media, i.e. USB, when it boots. It only supports detection of removable media while it is running. However, it is possible to configure Vadelma to search for removable media paths at startup but it requires that you know the exact mount path for drive. Usually this is /media/<NAME> where NAME is the identifier of the drive you'll see when it's inserted in any PC (Windows,Linux,Mac).
For example, a Kingston 8GB USB stick, when inserted in a MAC it's listed as KINGSTON.
Modify the settings.ini file and define a FileSystemPath. It should look similar to the snippet below. Remember to substitute KINGSTON with the name of your drive.
[FileSystemPath]
NAME=usb
PATH=/media/KINGSTON
Note: If Vadelma still doesn't detect your USB stick at start you must login to Vadelma and see how it's is mounted by typing command mount.
