| Text | This test case is to be carried out on a Raspberry Pi 4 2GB.
Follow the installation steps at
IoT installation media
-
Immediately after the "rainbow" splash screen, U-Boot starts. Press a key
to interrupt the sequence, then type "boot" to continue it.
-
Check that the U-Boot prompt (including a two-second wait) appears on
the primary monitor connected to the Pi, that the keyboard will interrupt
the sequence, and that boot successfully concludes after resumption.
-
During the boot sequence, U-Boot starts interacting via serial (GPIO14
and GPIO15, pins 8 and 10 respectively, on the 40-pin GPIO header). Press
a key to interrupt the sequence, then type "boot" to continue it.
-
Check that the U-Boot prompt (including a two-second wait) appears on
the attached serial console, that the keyboard will interrupt
the sequence, and that boot successfully concludes after resumption.
-
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 4 2GB. It should be in the region of 1.6-1.8GB.
-
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
-
Connect a USB keyboard to one of the USB2 (black) ports
-
Verify that keys typed on the keyboard appear on the console
-
Connect a USB keyboard to one of the USB3 (blue) ports
-
Verify that keys typed on the keyboard appear on the console
-
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
-
With an HDMI monitor that supports audio plugged into
the HDMI1 output, and an available MP3 file:
- Install mpg321 and amixer with
sudo apt install mpg321
alsa-utils
- Find the correct hardware output for the HDMI1 port:
cat /proc/asound/cards and note the number at the start
of the line for the HDMI1 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
-
With a pair of headphones with a 3.5mm jack, and an available MP3 file:
- Install mpg321 and amixer with
sudo apt install mpg321
alsa-utils
- Find the correct hardware output for the headphone jack:
cat /proc/asound/cards and note the number at the start
of the line for the headphone jack (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
-
Check auto-configuration of ethernet
- Run
ip addr
- Check that a valid IP address is recorded on the eth0 interface
- Check
ping google.com successfully pings a few times
(Ctrl+C to cancel)
-
The "eth0" interface should have a DHCP
assigned IP address and you should be able to ping google.com
-
Configure wifi via netplan
-
The "wlan0" interface should have a DHCP
assigned IP address and you should be able to ping google.com
