Hello jagan mohan, Please go through the below link for testing document of all the periperals of rugged board. https://developer.ruggedboard.com/g1-getting-started/test-all-the-rb-interfaces-in-10-mins

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. Target side: $ ip link set can0 down $ ip link set can0 type can bitrate 50000 $ ip link set can0 up $ cansend can0 123#1232 Host side: $ sudo ip link set can0 down $ sudo ip link set can0 type can bitrate 50000 $ sudo ip link set can0 up $ candump can0 $ can0 123 [2] 12 32 To Transmit packets from PC to Board Host side : sudo ip link set can0 down sudo ip link set can0 type can bitrate 50000 sudo ip link set can0 up sudo cansend can0 123#1232 Target side : ip link set can0 down ip link set can0 type can bitrate 50000 ip link set can0 up candump can0 can0 123 [2] 12 32 Expected o/p : To Transmit packets from board to PC Target side: root@sama5d27-som1-ek-sd:~# ip link set can0 down root@sama5d27-som1-ek-sd:~# ip link set can0 type can bitrate 50000 root@sama5d27-som1-ek-sd:~# ip link set can0 up root@sama5d27-som1-ek-sd:~# cansend can0 123#1232 Host side: USER@ubuntudesk:~$ sudo ip link set can0 down USER@ubuntudesk:~$ sudo ip link set can0 type can bitrate 50000 USER@ubuntudesk:~$ sudo ip link set can0 up USER@ubuntudesk:~$ sudo candump can0 can0 123 [2] 12 32 To Transmit packets from PC to Board Host side : USER@ubuntudesk:~$ sudo ip link set can0 down USER@ubuntudesk:~$ sudo ip link set can0 type can bitrate 50000 USER@ubuntudesk:~$ sudo ip link set can0 up USER@ubuntudesk:~$ sudo cansend can0 123#1232 Target side: root@sama5d27-som1-ek-sd:~# ip link set can0 down root@sama5d27-som1-ek-sd:~# ip link set can0 type can bitrate 50000 root@sama5d27-som1-ek-sd:~# ip link set can0 up root@sama5d27-som1-ek-sd:~# candump can0 can0 123 [2] 12 32

Rugged board having dual usb connector.Defaultly upper usb slot(USB 0) is working. Bottom usb slot will not work instead of that usb pcie connector will work

Could please check the eeprom with below commands echo phytec > /sys/class/i2c-adapter/i2c-0/0-0050/eeprom cat /sys/class/i2c-adapter/i2c-0/0-0050/eeprom

instead of la32-libs install i386 package. please give the below commnad sudo apt-get install i386
