1. 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.

2. Board Preparations

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

1. TBD: setup bluetooth in Torizon OS

Power on a Bluetooth device in the vicinity, validate that the target detects it:
user@imx8mpnavq:/home/user# sudo hcitool scan Scanning ... 50:1A:A5:E5:34:8A JABRA BT2045 F0:F6:1C:67:F4:D4 iPhone yur
Power on a BLE device in the vicinity, validate that the target detects it:
user@imx8mpnavq:/home/user# sudo hcitool lescan LE Scan ... 14:BB:6E:2F:9B:07 (unknown) ^C

TBD: add support for booting Torizon OS from SD card (NAVQP-237)
Make sure the system is booted from SD card.
Remove partition table from eMMC:
$ sudo dd if=/dev/zero of=/dev/mmcblk2 bs=8M count=100 conv=fdatasync
Reboot and check boot time is about ~25 seconds
$ sudo reboot

Disconnect all cables (except serial debug) to power off the board.
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.
Validate that the NAVQ Plus boots to login prompt normally (no boot loop).
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.
Validate that the NAVQ Plus boots to login prompt normally (no boot loop).

Disconnect the cable from USB1.
Reboot the board
Run usb-gadget-mtp1 service:
user@imx8mpnavq:~$ sudo systemctl start usb-gadget-mtp@38100000.usb [sudo] password for user: user@imx8mpnavq:~$
Connect the USB1 to a desktop host.
Verify that the host recognized NAVQ Plus as an MTP (“NavqPlus” device is shown in the Windows Explorer).

Power up device using USB1 port
Run usb-gadget-mtp2 service:
# 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:~$
Connect the USB2 to a desktop host/laptop.
Verify that the host/laptop recognized NAVQ Plus as an MTP.
Restore back USB Ethernet gadget on USB2 (or just do “sudo reboot” instead):
user@imx8mpnavq:~$ sudo systemctl stop usb-gadget-mtp@38200000.usb [sudo] password for user: user@imx8mpnavq:~$ sudo systemctl start usb-gadget-eth@38200000.usb

Make sure HDMI display and USB Mouse are connected to the kit.
Copy the test file https://emcraft.com/misc/test.rrf to a USB Flash. Insert the USB Flash into the kit.
From the shell prompt, on the serial console, run PMD RoyaleViewer:
user@imx8mpnavq:~$ royaleviewer.sh ...
On the HDMI display, navigate to “Tools” → “Load File” and load the test file.
Verify that RoyaleViewer plays the saved frames correctly.
