Note 4

Sample commands for wifi testing:

ifconfig eth0 down
echo "nameserver 8.8.8.8" > /etc/resolv.conf
ifconfig wlan0 up
iw dev wlan0 scan | grep SSID
wpa_passphrase SSID password > /etc/wpa_supplicant.conf
wpa_supplicant -iwlan0 -Dnl80211 -c/etc/wpa_supplicant.conf -B

On walnascar wpa_supplicant 2.11 doen't work properly with brcmfmac driver. If you want to use wpa_supplicant include the package:

    brcmfmac-fix \

in your image.

If you have rfkill enabled in kernel command ifconfig wlan0 up may fail due to rfkill. Type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD

So type:

rfkill unblock 0

to unlock wlan.

Alternatively you can use iwd. Remember to uncomment the line

Note 7

Play back an audio file with command:

aplay /tmp/test-mic.wav

Note 8

Connect J13 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).

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.

Connect TX/RX PIN connector J11 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 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:

Note 4

Sample commands for wifi testing:

ifconfig eth0 down
echo "nameserver 8.8.8.8" > /etc/resolv.conf
ifconfig wlan0 up
iw dev wlan0 scan | grep SSID
wpa_passphrase SSID password > /etc/wpa_supplicant.conf
wpa_supplicant -iwlan0 -Dnl80211 -c/etc/wpa_supplicant.conf -B
udhcpc -i wlan0

On walnascar wpa_supplicant 2.11 doen't work properly with brcmfmac driver. If you want to use wpa_supplicant include the package:

    brcmfmac-fix \

in your image.

If you have rfkill enabled in kernel command ifconfig wlan0 up may fail due to rfkill. Type:

rfkill

Example output:

ID TYPE      DEVICE    SOFT      HARD
 0 wlan      phy0   blocked unblocked

So type:

rfkill unblock 0

to unlock wlan.

Alternatively you can use iwd. Remember to uncomment the line

WIRELESS_DAEMON = "iwd"

inside recipe /recipes-core/packagegroups/packagegroup.bbappend.

At first use type:

$ iwctl

iwd automatically stores network passphrases in the /var/lib/iwd directory and uses them to auto-connect in the future.

Commands for bluetooth testing:

brcm_patchram_plus \
  --patchram /etc/firmware/BCM43430A1.1DX.hcd \
  --enable_hci --no2bytes --tosleep 1000 \
  /dev/ttyUSB0 &

hciconfig hci0 up
hcitool scan

If you have rfkill enabled in kernel after the brcm_patchram_plus 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.
