The TS-7670 i.MX286 CPU has two FlexCAN ports that use the linux SocketCAN implementation. The ports can be set up and used with the following commands:
modprobe flexcan
ifconfig can0 up
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. In order to test the two ports together, tie CAN_H of both CAN ports together, and do the same for CAN_L. Then use the following commands:
candump can0 &
cansend can1 123#DEADBEEF
#This command will return
can0 123 [4] DE AD BE EF
See the SocketCAN webpage for more information on utilizing SocketCAN.
