Testcase (Report an issue with this testcase)

This test case is to be carried out on a Raspberry Pi Compute Module 3+.

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 Compute Module 3+. It should be in the region of 800-1000MB.
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 ports
Verify that keys typed on the keyboard appear on the console
With an HDMI monitor that supports audio, and an available MP3 file:
  • Install mpg321 and amixer with sudo apt install mpg321
    alsa-utils
  • Find the correct hardware output for the HDMI port:
    cat /proc/asound/cards and note the number at the start
    of the line for the HDMI 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
