RaspberryPi 400 Desktop SD in Ubuntu Desktop arm64+raspi in Jammy Daily (archived)

This test case is to be carried out on a Raspberry Pi 400.
Follow the installation steps at
IoT installation media, and write the image to an SD card.
Then, using sudo rpi-eeprom-config, ensure the EEPROM's
BOOT_ORDER
is set to 0xf1.

Watch the power LED

Ensure it turns on at boot time, and stays lit as the kernel starts
(when the rainbow screen disappears)

Watch the boot screen

Check that the Ubuntu logo, and spinner appear during boot time

Ensure you have speakers on your monitor or headphones plugged into it

Check that the Ubuntu start up sound plays through the monitor's audio
output before the initial System Configuration appears

Select your timezone, and click on the Continue button

The 'Who are you?' screen appears

Input your initial user details and password
admin can not be used - it is a dedicated Linux User

Name, username and password are accepted. Login options and home folder
encryption choices shown

Continue button becomes available

Run sudo flash-kernel

Exit code is clean (0) and no error messages are reported

Click the power icon at the top right of the screen, and expand the "Power
Off / Log Out" entry in the menu that appears, then "Restart..." from that
menu, and confirm "Restart" in the dialog that appears

System reboots successfully to a login prompt

Click the power icon at the top right of the screen, and expand the "Power
Off / Log Out" entry in the menu that appears, then "Power Off..." from
that menu, and confirm "Power Off" in the dialog that appears

System shuts down in a reasonable time (less than a minute)

Launch Settings from
the menu that appears, then "About" in the left panel of the window that
appears

Reported "Memory" is consistent with a Raspberry Pi 400.
It should be in the region of 3.6-3.8GB.

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 Network Manager

• Launch settings
• Select the WiFi entry from the menu
• Select your local WiFi network from the visible networks list
• Enter the password for your local WiFi network when prompted
• 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
• Disconnect ethernet, if any is plugged in
• Check ping google.com successfully pings a few times
  (Ctrl+C to cancel)
• Reconnect ethernet, if it was connected before

The "wlan0" interface should have a DHCP
assigned IP address and you should be able to ping google.com

Configure bluetooth and pair a device

• Launch settings
• Select the Bluetooth entry from the menu (you must be on this page
  for the Pi to be "discoverable")
• On another Bluetooth device (e.g. an Android phone) make sure it
  is "discoverable" (e.g. on Android go into Bluetooth
  settings)
• Ensure the other device shows up in the "Devices" list
  on the Bluetooth settings page, then select it
• Confirm the pincode on both devices
• Ensure the other device now shows as anything other that "Not
  Set Up" in the "Devices" list

The Bluetooth interface can scan for, and pair with, another device

Start Firefox and play a YouTube video

• Ensure you have functioning speakers / a headset plugged into your
  monitor
• Click on the Firefox icon on the left of the screen
• Navigate to YouTube
• Select a video (with audio!) to play

Check the video plays smoothly, and that audio is output through the
monitor, or speakers / headset plugged into the monitor

Download and play BigBuckBunny in the built-in video player

• Ensure you have functioning speakers / a headset plugged into your
  monitor
• Start a terminal session
• Run wget https://archive.org/download/BigBuckBunny_124/Content/big_buck_bunny_720p_surround.mp4
• Once the download has completed, run totem big_buck_bunny_720p_surround.mp4
• The utility may prompt to install codecs; accept the recommendation
  and install whatever codecs are required

Check the video plays smoothly, and that audio is output through the
monitor, or speakers / headset plugged into the monitor

Press Super+L and wait for the lock screen to appear, then
fade, then for the monitor to suspend. Move the mouse to wake up the
monitor, then enter your password to unlock the desktop.

Ensure the monitor suspends correctly, that it awakens again correctly,
and that the desktop unlocks successfully (without the system hanging).

Check the CPU clock speed using vcgencmd

• Stress the CPU by doing yes > /dev/null &
• Run sudo vcgencmd measure_clock arm after about 5 sec
• Kill the stress process

The output should be around 1.8GHz (obtained from online specs)

Run sudo vcmailbox 0x00010004 8 8 0 0

The output should have the board serial number as the 6th integer.

Test dtmerge

• Copy the live device tree using dtc -I fs -O dtb -o test.dtb /proc/device-tree
• Use dtmerge to overclock the SD card. dtmerge test.dtb merged.dtb - sd_overclock=62
• Check the contents of the new DTB. dtdiff test.dtb merged.dtb
• Delete both test.dtb and merged.dtb

merged.dtb should have brcm,overclock-50 = 0x3e under the SD card device.

Test dtoverlay

• Run sudo dtoverlay pwm
• Run sudo dtoverlay -l

The PWM Overlay should show up as loaded. Remove it by running sudo dtoverlay -r pwm

Test dtparam

• Run sudo dtparam sd_overclock=62
• Run sudo dtparam -l

The sd_overclock parameter should show up as set. Remove it by running sudo dtparam -r 0

Run sudo pinctrl

THe output should have status of the GPIO pins.

Run sudo raspinfo

The output should have an information dump about the Pi.
