For testing CAN, canutils package is highly recommended. We are not providong canutils packge along with NOR flash. So please boot the board from SD card and follow the below steps to test the can. 1.Boot the board from MMC. 2. After booting,check the interface is available or not by giving the below command. $ ifconfig can0 3.To Transmit packets from board to PC. Connect the PCAN device. Give the below commands to test can.
