Serial Download

Close JM2 and keep JM1 open to enable serial download. Connect the board with the source machine (i.e. the machine you are downloading the images from) by using the board's OTG header (J8).

Power on the board.

From source machine check if an USB device for serial download is detected:

uuu -lsusb

Output:

Note 4

Sample commands for wifi testing:

modprobe moal mod_para=nxp/wifi_mod_para.conf
ifconfig mlan0 up
iw dev mlan0 scan | grep SSID
wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant.conf
wpa_supplicant -imlan0 -Dnl80211 -c/etc/wpa_supplicant.conf -B
udhcpc -imlan0
echo "nameserver 8.8.8.8" > /etc/resolv.conf

If you have rfkill enabled in kernel command ifconfig mlan0 up may fail due to rfkill. Type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD
 0 mlan      phy0   blocked unblocked

So type:

rfkill unblock 0

to unlock mlan.

Try to ping some machines and known sites.

Note 5

Commands for bluetooth testing:

hciattach -b /dev/ttymxc3 any 3000000 flow
hciconfig hci0 up
hcitool scan

If you have rfkill enabled in kernel after the hciconfig hci0 up command type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD
 0 wlan      phy0   blocked unblocked
 1 bluetooth hci0   blocked unblocked

So type:

rfkill unblock 1

to unlock bluetooth.

Note 6

Set a time and date to the clock:

date -s "2000-01-01"
hwclock -w && sync

Turn off the system and power it back on. Once it booted check that the date is the same:

Note 7

Record an audio file with command:

arecord -d 5 -f S16_LE /tmp/test-mic.wav

then play and check with command:

aplay /tmp/test-mic.wav

Note 8

Connect J19 header to another board CAN header and configure related can links on both ends of the connection:

End A:

ip link set can0 type can bitrate 125000

End B (for example on other board, can1):

ip link set can1 type can bitrate 125000

Enable interfaces on both ends:

End A:

ifconfig can0 up

End B (for example on other board, can1):

ifconfig can1 up

Make End A listen:

cantest can0

Send a frame from End B:

cantest can1 5A1#11.2233.44556677.88

Check output on End A:

read 16 bytes

Once done do:

usb stop

stopping USB..

to safely remove storage devices.

Serial Download

Close JM2 and keep JM1 open to enable serial download. Connect the board with the source machine (i.e. the machine you are downloading the images from) by using the board's OTG header (J8).

Power on the board.

From source machine check if an USB device for serial download is detected:

uuu -lsusb

Output:

uuu (Universal Update Utility) for nxp imx chips -- lib1.5.141

Connected Known USB Devices
    Path     Chip    Pro     Vid     Pid     BcdVersion
    ==================================================
    1:1  MX865   SDPS:   0x1FC9 0x0146   0x0002

Here we see a device is detected. Then type:

uuu -v -b emmc_all imx-boot engicam-evaluation-image-mx93-imx93-icore.rootfs.wic.zst/*

And wait for the download and flash of eMMC to finish.

Note 1

Connect board's ethernet with your machine's one.

On your machine launch iperf3 server by typing:

iperf3 -s

On board launch iperf3 in client mode:

iperf3 -c 192.168.10.1

Using the IP address of your server machine.

Output:

Note 2

Connect TX/RX PIN connector J18 to the UART 232 port From terminal launch command:

test_serial ttyLP7

Verify that the characters written from keyboard are echoed in terminal.

Note 3

Tested with other RS485 device connected (J18) with command:

test_serial2 -d /dev/ttyLP4 -b 115200

Be sure to launch the command test_serial2 on both devices to see the communication between devices on the terminal:

Device = /dev/ttyLP4, Baudrate = 115200

Note 4

Sample commands for wifi testing:

modprobe moal mod_para=nxp/wifi_mod_para.conf
ifconfig mlan0 up
iw dev mlan0 scan | grep SSID
wpa_passphrase SSID PASSWORD > /etc/wpa_supplicant.conf
wpa_supplicant -imlan0 -Dnl80211 -c/etc/wpa_supplicant.conf -B
udhcpc -imlan0
echo "nameserver 8.8.8.8" > /etc/resolv.conf

If you have rfkill enabled in kernel command ifconfig mlan0 up may fail due to rfkill. Type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD
 0 mlan      phy0   blocked unblocked

So type:

rfkill unblock 0

to unlock mlan.

Try to ping some machines and known sites.

Note 5

Commands for bluetooth testing:

hciattach -b /dev/ttyLP1 any 3000000 flow
hciconfig hci0 up
hcitool scan

If you have rfkill enabled in kernel after the hciconfig hci0 up command type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD
 0 wlan      phy0   blocked unblocked
 1 bluetooth hci0   blocked unblocked

So type:

rfkill unblock 1

to unlock bluetooth.

Note 6

Set a time and date to the clock:

date -s "2000-01-01"
hwclock -w && sync

Turn off the system and power it back on. Once it booted check that the date is the same:

hwclock

Note 7

Tested with command:

gst-launch-1.0 -v videotestsrc  ! capsfilter caps="video/x-raw, width=1024, height=600"  !  autovideosink

Note 8

Tested with command:

echo <n> > /sys/class/backlight/backlight/brightness

where n is an integer from 0 to 100

Note 9

Tested with command:

evtest /dev/input/event0

Note 10

Record an audio file with command:

arecord -d 5 -f S16_LE /tmp/test-mic.wav

then play and check with command:

aplay /tmp/test-mic.wav

Note 11

Connect J19 header to another board CAN header and configure related can links on both ends of the connection:

End A:

ip link set can0 type can bitrate 125000

End B (for example on other board, can1):

ip link set can1 type can bitrate 125000

Enable interfaces on both ends:

End A:

ifconfig can0 up

End B (for example on other board, can1):

ifconfig can1 up

Make End A listen:

cantest can0

Send a frame from End B:

cantest can1 5A1#11.2233.44556677.88

Check output on End A:

read 16 bytes
5A1  [8] 11 22 33 44 55 66 77 88

Do the same from B to A (make B listen and A send a frame).

Note 12

Use benchmark tool Glmark2:

glmark2-es2-wayland

Note 13
