RaspberryPi CM4 2GB Post-install in Ubuntu Server arm64+raspi in Jammy Daily (archived)

This test case is to be carried out on a Raspberry Pi Compute Module 4 2GB.
Follow the installation steps at
IoT installation media

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 Compute Module 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

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

With an HDMI monitor that supports audio plugged into
the HDMI1 output, and an available MP3 file:

• Install ffmpeg and amixer with sudo apt install ffmpeg
alsa-utils
• Find the correct card name for the HDMI1 port:
  cat /proc/asound/cards and note the name in [brackets]
  for the HDMI1 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

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

• Place the following in /etc/netplan/wifi.yaml
  (substituting the SSID and password as necessary):

•       network:
          version: 2
            wifis:
              wlan0:
                dhcp4: true
                access-points:
                  my-ssid-here:
                    password: my-password-here

• Run sudo netplan apply
• Wait a few seconds (to allow DHCP to complete), then run ip
addr
• Check that a valid IP address is recorded on the wlan0 interface
• Check ping google.com successfully pings a few times
  (Ctrl+C to cancel)

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.
