Purpose

This document provides a description of the QA tests used for validation of i.MX 8M Plus Starter Kit weekly engineering builds and release builds.

Board Preparations

Connect to the board (see Setting up the i.MX 8M Plus SOM Starter Kit ):

  • Ethernet cable

  • WiFi antenna

  • USB hub, with USB keyboard and mouse attached, into the USB1 connector.

  • HDMI monitor

QA Tests

SD Installation and Booting Test

  1. Install release image to SD card, as per Flashing SD Card with Linux Image from Linux Host .

  2. Boot to shell prompt using SD card, measure boot time (~25 seconds).

Ethernet Test

  1. Check that internet access is configured automatically.

  2. Run ping google.com.

USB Flash Test

  1. Insert USB Flash to USB hub. Run “lsblk”. Make sure /dev/sda and /dev/sda1 are present:

    Code Block
    user@imx8mpnavq:~$ lsblk
NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
sda            8:0    1 28.9G  0 disk
└─sda1         8:1    1 28.9G  0 part /media/user/BEF4-F228
...

WiFi Test

  1. Unplug Ethernet cable.

  2. Configure and test WiFi as per Setting up Wi-Fi.

HDMI Test

  1. Check that login is displayed on HDMI monitor.

  2. Login to desktop using USB keyboard and mouse (“user” account).

  3. Start Chromium browser (upper left corner->"nine dots"->Chromium browser).

  4. Open https://staging.voxelbotics.com page.

BlueTooth Test

  1. Bluetooth is configured automatically in recent builds (starting from 1.1.5-359, 0.0.1-358). If you are using an older build, refer to Setting up Bluetooth for configuring Bluetooth before tests.

  2. Power on a Bluetooth device in the vicinity, validate that the target detects it:

    Code Block
    user@imx8mpnavq:/home/user# sudo hcitool scan
Scanning ...
        50:1A:A5:E5:34:8A       JABRA BT2045
        F0:F6:1C:67:F4:D4       iPhone yur

  3. Power on a BLE device in the vicinity, validate that the target detects it:

    Code Block
    user@imx8mpnavq:/home/user# sudo hcitool lescan
LE Scan ...
14:BB:6E:2F:9B:07 (unknown)

Empty eMMC boot time test

  1. Make sure the system is booted from SD card.

  2. Remove partition table from eMMC:
    $ sudo dd if=/dev/zero of=/dev/mmcblk2 bs=8M count=100 conv=fdatasync

  3. Reboot and check boot time is about ~25 seconds
    $ sudo reboot

eMMC installation and booting test

  1. Install images to eMMC as per Installing Linux to the EMMC using USB Serial Downloader.

  2. Repeat Ethernet, WiFi and HDMI tests while booting from eMMC.

USB2-only power test

  1. Disconnect all cables (except serial debug) to power off the board.

  2. Use Type-C to Type-C cable and plug it into NAVQ Plus USB2 Type-C (closer to center) and a Laptop with Type-C port.

  3. Validate that the NAVQ Plus boots to login prompt normally (no boot loop).

  4. Use Type-A to Type-C cable and plug it into NAVQ Plus USB2 Type-C (closer to center) and a Laptop/Desktop with Type-A port.

  5. Validate that the NAVQ Plus boots to login prompt normally (no boot loop).

USB1 Host Mode test

  1. Plug-in a USB hub into USB1.

  2. Power Up device via USB2.

  3. Plug-in a USB device into the hub.

  4. Verify that the plugged-in device is enumerated (via dmesg).

USB1 Device Mode test

  1. Disconnect the cable from USB1.

  2. Reboot the board

  3. Run usb-gadget-mtp1 service:

    Code Block
    user@imx8mpnavq:~$ sudo systemctl start usb-gadget-mtp@38100000.usb
[sudo] password for user: 
user@imx8mpnavq:~$

  4. Connect the USB1 to a desktop host.

  5. Verify that the host recognized NAVQ Plus as an MTP (“NavqPlus” device is shown in the Windows Explorer).

USB2 Device Mode test

  1. Power up device using USB1 port

  2. Run usb-gadget-mtp2 service:

    Code Block
    # Stop the Ethernet gadget on USB2, enabled by default in imx-image-desktop-ros image.
user@imx8mpnavq:~$ sudo systemctl stop usb-gadget-eth@38200000.usb 
[sudo] password for user: 
...
user@imx8mpnavq:~$ sudo systemctl start usb-gadget-mtp@38200000.usb
user@imx8mpnavq:~$

  3. Connect the USB2 to a desktop host/laptop.

  4. Verify that the host/laptop recognized NAVQ Plus as an MTP.

  5. Restore back USB Ethernet gadget on USB2 (or just do “sudo reboot” instead):

    Code Block
    user@imx8mpnavq:~$ sudo systemctl stop usb-gadget-mtp@38200000.usb
[sudo] password for user: 
user@imx8mpnavq:~$ sudo systemctl start usb-gadget-eth@38200000.usb

RoyaleViewer/Qt test

  1. Make sure HDMI display and USB Mouse are connected to the kit.
