Text | This test case is to be carried out on a Raspberry Pi Zero 2.
Follow the installation steps at
IoT installation media
-
After powering on the machine, look at the power LED
-
The power LED illuminates and stays illuminated while the kernel continues
to boot.
On the Pi Zero 2W, the LED may blink off periodically to show disk
activity, but should otherwise remain lit.
-
After logging in, run
systemctl status , and look at the
"State:" reported at the top of the output
-
State should be reported as "running". In particular, it should
not read "degraded".
-
Run
sudo flash-kernel
-
Exit code is clean (0) and no error messages are reported
-
Run
sudo reboot
-
System reboots successfully to a login prompt
-
Run
sudo shutdown -h now
-
System shuts down in a reasonable time (less than a minute)
-
Check output of
free -h
-
Reported "Mem" under "total" is consistent with a
Raspberry Pi Zero 2. It should be in the region of 300-500MB.
-
Perform a large (300-600MB) file copy to USB storage
- Generate a large (500MB) file:
dd if=/dev/urandom of=rubbish
bs=1M count=500
- Insert a USB stick (appropriately sized) into a spare USB port
- Make a mount directory:
sudo mkdir /mnt/stick
- Mount the stick:
sudo mount /dev/sda1 /mnt/stick
(modify mount-point as necessary; check sudo dmesg
output if unsure)
- Copy the file:
sudo cp rubbish /mnt/stick/
- Unmount the stick:
sudo umount /mnt/stick
- Remove the stick from the USB port
- Re-insert the stick into the USB port
- Re-mount the stick:
sudo mount /dev/sda1 /mnt/stick
(again, adjust mount-point as necessary)
- Compare the copied file to that on the stick:
cmp rubbish
/mnt/stick/rubbish
-
cmp returns 0 and outputs nothing, indicating the files are
identical
-
With an HDMI monitor that supports audio plugged into
the HDMI0 output, and an available MP3 file:
- Install ffmpeg and amixer with
sudo apt install ffmpeg
alsa-utils
- Find the correct card name for the HDMI0 port:
cat /proc/asound/cards and note the name in [brackets]
for the HDMI0 port
- Attempt to play your MP3 file with:
ffmpeg -i
music.mp3 -f alsa default:CARD=name
substituting name for the card name found during the
previous step, and music.mp3 for your choice of MP3 file,
e.g. mpg321 -o alsa -a hw:0,0 "Jeff Wayne - War of the
Worlds.mp3"
- Use Ctrl+C or q to end playback early, if you
wish
- If you cannot hear anything, first check that the mixer's volume is
not set too low; run alsamixer , and adjust the volume
(J for down, K for up) before exiting
(Esc) and retrying playback
- Audio can be heard through the device
-
Configure wifi via netplan
-
The "wlan0" interface should have a DHCP
assigned IP address and you should be able to ping google.com
-
Configure bluetooth, scan for, and pair, a device
- Install bluez with
sudo apt install bluez
- Run
sudo bluetoothctl
- Check bluetoothctl prints
Agent registered
- Check the MAC address looks "real" (not some obviously blank
value like AA:AA:AA:AA:AA:AA)
- Run
scan on
- Make some other Bluetooth device visible for pairing (e.g. go into
Bluetooth settings on your Android phone)
- Verify the other Bluetooth device appears in console output
- Run
pair XX:XX:XX:XX:XX:XX
where XX:XX:XX:XX:XX:XX is the other device's MAC address, as it
appears in scan output
- Verify the passcode on both devices
- Check output includes "Pairing successful"
- Disable scanning with
scan off
- Exit tool with
quit
-
The Bluetooth interface should have a valid MAC address (not
AA:AA:AA:AA:AA:AA), can see and pair with another Bluetooth device.
