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.
-
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 mpg321 and amixer with
sudo apt install mpg321
alsa-utils
- Find the correct hardware output for the HDMI0 port:
cat /proc/asound/cards
and note the number at the start
of the line for the HDMI0 port (usually 0 and possibly
1 for any connected monitor(s), and 1 or possibly 2 for the headphone
jack)
- Attempt to play your MP3 file with:
mpg321 -o alsa -a
hw:num,0 music.mp3
substituting
num for the number 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 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
