Micro SD card
Micro USB cable
Router or switch with Ethernet cable
Booting from an SD card
Building 1. Downloading the buildroot image from source:1. Clone our GitHub repository
Downlaod the Buildroot image by running the following command on your Linux/Windows PC
| Code Block |
|---|
git clone git@github.com:SolidRunwget https://solid-run-images.sos-de-fra-1.exo.io/AM64X/ti_am64x_build.git |
2. Image Build
Follow the documentation to build the image.
...
/microsd-3e15611.img.xz |
For more Buildroot releases, please visit Buildroot Releases for AM64X based SOM.
2. Write the image to an SD card
| Code Block |
|---|
sudo xz dd if=output/-dc microsd-<hash>3e15611.img.xz | dd of=/dev/sdX bs=4M conv=fsync status=progress |
For more information, please visit Flashing an SD Card.
...
Connect your power adaptor to the DC jack, and then connect the adaptor to the mains supply.
| Tip |
|---|
A green LED will light up at the front panel. This is an indication of boot loader firmware is running.If you find you need additional help, please contact us and we’ll do our best to get back to you with more personal support. |

CanBUS communication
1. Enable device can0 (for ex):
| Code Block |
|---|
devicecan_num=ttyS5can0 rs485conf /dev/$device -e 1 -o 0 -a 1 -r 1 ip link set $can_num up type can bitrate xxxxxx |
(ex: 125000)
2. Bring the CAN interface up:
| Code Block |
|---|
ifconfig can0 up |
3. Print all data received by CAN interface to “can_test” file (for ex):
| Code Block |
|---|
touch /tmp/rs485can_test stty -Fcandump $can_num >> /devtmp/$device raw -echo -echoe -echok #Print received data to rs485_test file cat /dev/$device > /tmp/rs485_test & echo "OK" > /dev/$device & |
...
can_test & |
4. Send data to the bus by executing (for ex):
| Code Block |
|---|
cansend $can_num "123#1234" |
5. Check received data by opening “can_test” file:
| Code Block |
|---|
cat /tmp/can_test |
Test RS485 communication
The following is an example of testing RS485 communication:
1. Configure RS485 device as follows:
| Code Block |
|---|
device=ttyS5
rs485conf /dev/$device -e 1 -o 0 -a 1 |
RS485 configuration should look as follows:
| Code Block |
|---|
= NewCurrent 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: true |
Receive mode
| Code Block |
|---|
device=ttyS5 rs485conf /dev/$device -e 1 -o 1 -a 0 -r 1 false |
2. Print all data received to “rs485_test” file (for ex):
| Code Block |
|---|
touch /tmp/rs485_test stty -F /dev/$device raw -echo -echoe -echok #Print received data to rs485_test file cat /dev/$device > /tmp/rs485_test & |
3. Send data by executing:
| Code Block |
|---|
echo "OK" > /dev/$device & |
On receive mode, the RS485 configuration should look as follows4. Check received data by opening “rs485_test” file:
| Code Block |
|---|
= New configuration: RS485 enabled: true RTS on send: high RTS after send: low RTS delay before send: 0 RTS delay after send: 0 Receive during sending data: truecat /tmp/rs485_test |
