• Router or switch with Ethernet cable

Booting from an SD card

1. Downloading the buildroot image

Download the Buildroot image by running the following command on your Linux/Windows PC

wget https://solid-run-images.sos-de-fra-1.exo.io/AM64X/ti_am64x_build/microsd-937be33.img.xz

• For more Buildroot releases, please visit Buildroot Releases for AM64X-based SOM.

2. Write the image on an SD card

 xz -dc microsd-937be33.img.xz | dd of=/dev/sdX bs=4M conv=fsync status=progress

• For more information, please visit Flashing an SD Card.

4. SD card insertion

Please Insert the SD card into your device.

5. Power connection

Connect your power adaptor to the DC jack, and then connect the adaptor to the mains supply.

6. Serial Connection

Please insert the micro USB into your device, then you can refer to Serial Connection for installing the necessary serial connection software in Linux/Windows.

CanBUS and RS485

Test CanBUS communication

1. Enable device can0 :

can_num=can0
ip link set $can_num up type can bitrate xxxxxx

• (ex: 125000)

2. Bring the CAN interface up:

ifconfig can0 up

3. Print all data received by the CAN interface to “can_test” file :

touch /tmp/can_test
candump $can_num >> /tmp/can_test &

4. Send data to the bus by executing :

cansend $can_num "123#1234"

5. Check the received data by opening “can_test” file :

cat /tmp/can_test

Test RS485 communication

The following is an example of testing RS485 communication :

1. Configure the RS485 device as follows:

device=ttyS5
rs485conf /dev/$device -e 1 -o 0 -a 1 

• RS485 configuration should look as follows:

= Current configuration:
RS485 enabled:                true
RTS on send:                  low
RTS after send:               high
RTS delay before send:        0
RTS delay after send:         0
Receive during sending data:  false

2. Print all data received to “rs485_test” file (for ex):

touch /tmp/rs485_test
stty -F /dev/$device raw -echo -echoe -echok
cat /dev/$device > /tmp/rs485_test &

3. Send data by executing:

echo "OK" > /dev/$device &

4. Check the received data by opening “rs485_test” file:

cat /tmp/rs485_test
