The CPU brings out one CAN port compatible with the linux SocketCAN implementation. The ports can be set up and used with the following command:
ifconfig can1 up
In order to set the baud rate of the CAN interface, the interface must first be brought down with:
ifconfig can1 down
At this point, the desired baud rate can be directly entered in to the file "/sys/devices/platform/FlexCAN.1/bitrate". For example, to set a baud rate of 750kHz on the interface:
ifconfig can1 down
echo 750000 > /sys/devices/platform/FlexCAN.1/bitrate
ifconfig can1 up
At this point the ports can be used with standard SocketCAN libraries. In debian we provide cansend and candump to test the ports or as a simple packet send/recv tool. The following are some simple commands that can be used:
candump can1
cansend can1 7Df#03010c
