Troubleshooting 6.1 Unable to restart the CAN interface 6.2 Installing the Moxa CAN Driver in Kernel 2.6.31 ----------------------------------------------------------------------------- 1. Introduction The CAN family Linux driver supports the following CAN boards: - 2-port CAN boards: CP-602E-I, CP-602U-I, CB-602I This driver and installation procedure have been developed upon Linux Kernel 3.x. This driver supports Intel x86/x64 hardware platforms. In order to maintain compatibility, this version has also been properly tested with Ubuntu Linux. However, if compatibility problem occurs, please contact Moxa at support@moxa.com. All the drivers are published in the form of source code under the GNU General Public License in this version. Please refer to the GNU General Public License announcement in each source code file for more details. Visit www.moxa.com to download the latest driver. This version of driver can be installed as loadable module (module driver). Before you install the driver, please refer to the hardware installation procedure in the User's Manual. The user should be familiar with the following documents: - Linux SocketCAN - Kernel-HOWTO ----------------------------------------------------------------------------- 2. System Requirements - Hardware platform: Intel x86/x64 machine - Kernel version: 2.6.31 or newer - GCC version 4.6.1 or later ----------------------------------------------------------------------------- 3. Installation 3.1 Hardware Installation PCI IRQ Sharing ----------- Each port within the same multiport board shares the same IRQ. Up to four Moxa CAN PCI family boards can be installed together on one system and share the same IRQ. 3.2 Driver Files The driver file may be obtained from the CD-ROM or website. The first step is to copy the driver file "driv_linux_CAN_vx.x_build_yymmddhh.tgz" into the specified directory, e.g. /moxa. Follow the executed commands below. # cd / # mkdir moxa # cd /moxa # cp /mnt/cdrom//driv_linux_CAN_vx.x_build_yymmddhh.tgz ./ # tar -xvzf driv_linux_CAN_vx.x_build_yymmddhh.tgz Note: xx=version, yy=year, mm=month, dd=day, hh=hour 3.3 Device Naming Convention Device naming rule ----------------------------------------------- The following is the naming convention for CAN boards as assigned by system: Board Num. Interface Name 1st board mxcan0, mxcan1 2nd board mxcan2, mxcan3 3rd board mxcan4, mxcan5 4th board mxcan6, mxcan7 You will find all the driver files in /moxa/mxcan. The following installation procedure depends on the model you'd like to run the driver. 3.4 Module Driver Configuration ------------- Preparing to Use the MOXA Driver -------------------- 3.4.1 Building the MOXA Driver Before using the MOXA driver, you will need to compile all the source code. This step needs to be executed only once. However, if you modify the source code, you will need to recompile the source code, and perform this step again. Find "Makefile" in /moxa/mxcan, then run # make; 3.4.2 Installing the MOXA Driver To install the MOXA driver, you have to execute the command below in /moxa/mxcan directory. The driver will then be installed in the system directory. # make install ------------- Loading the MOXA Driver -------------------- 3.4.3 To load the MOXA driver, execute the command below. # modprobe mxcandrv This command will activate the module driver. You may run "lsmod" to check if "mxcandrv" is activated. To simplify the processes above, we provided a single step to build, install, and load the MOXA driver. You may execute the ./mxinstall in /moxa/mxcan to start using the product. # ./mxinstall ------------- Loading the MOXA Driver on Boot -------------------- 3.4.4 From the above description, you may manually execute "modprobe mxcandrv" to activate this driver and run "rmmod mxcandrv" to remove it. However, it is better to have a boot time configuration to eliminate manual operation. Boot time configuration may differ with each distribution. The following steps may apply to common distributions: # vi /etc/modules.conf or # vi /etc/modules Append the following line to the file. mxcandrv Reboot and check if mxcandrv has been activated by the "lsmod" command. ------------- Unloading the MOXA Driver Manually -------------------- 3.4.5 Execute the command below to unload the MOXA driver manually # modprobe -r mxcandrv This command will deactivate the module driver. You may run "lsmod" to check if "mxcandrv" is deactivated or not. If the driver is marked as a permanent driver, it means the kernel prevented dynamic unload of modules. Please refer to kernel documents for detailed information. ------------- Cleaning the MOXA Driver -------------------- 3.4.6 Execute the command below to clean the files. # make clean ------------- Uninstalling the MOXA Driver and Utilities -------------------- 3.4.7 The MOXA driver and utilities will be removed from the system respectively after executing the command below in /moxa/mxcan. # make uninstall If the driver is marked as a permanent driver, reboot the system to remove the driver from memory. ----------------------------------------------------------------------------- 4. CAN Interface Operation 4.1 Displaying the CAN Interfaces # ip link show 4.2 Setting Bitrate Type the following to set the interface as bitrate 50000. When the driver is loaded for the first time, the bitrate is 0. # ip link set mxcanX type can bitrate 50000 4.3 Setting the CAN Interfaces Up or Down Users may set the interface up or down. Set the interface up to receive and transmit data. Set the interface down to configure the settings. The bitrate should be set correctly before setting the interface up. # ip link set mxcanX up or # ifconfig mxcanX up Type the following to set the interface down. # ip link set mxcanX down or # ifconfig mxcanX down 4.4 Restarting from Bus-Off State If the CAN bus detects too many errors, it will enter the bus-off state. Set an auto recovery time from the bus-off state with the following command: # ip link set mxcanX type can restart-ms 100 Or manually restart the interface. # ip link set mxcanX type can restart Note that a restart will also create a CAN error frame. 4.5 The procfs Directory The processes and system information is provided by the CAN bus core in the following files. Users may need to load the CAN filter manually to access these files. # modprobe can Use similar usage to read the information. # cat /proc/net/can/rcvlist_all rcvlist_all - list for unfiltered entries rcvlist_eff - list for single extended frame (EFF) entries rcvlist_err - list for error frames masks rcvlist_fil - list for mask/value filters rcvlist_inv - list for mask/value filters (inverse semantic) rcvlist_sff - list for single standard frame (SFF) entries Additional files found in /proc/net/can: stats - SocketCAN core statistics reset_stats - manual statistic reset version - prints the SocketCAN core version and the ABI version ----------------------------------------------------------------------------- 5. Utilities and Test Procedure 5.1 Utilities The canutils is a set of popular SocketCAN tools. You may download and test the CAN interface as well. http://www.pengutronix.de/software/socket-can/download/canutils/ To install the canutils, you need libsocketcan library in your system. http://www.pengutronix.de/software/libsocketcan/download/ The contents of canutils are listed below. canconfig - configure a CAN bus interface candump - dump messages from the CAN bus interface to stdout canecho - loop back received CAN messages to the interface cansend - send data on a CAN interface 5.2 Test Procedure When the CAN driver is installed, type the following to test a 2-port CAN card. # modprobe mxcandrv # ip link set mxcan0 type can bitrate 50000 # ip link set mxcan0 up # ip link set mxcan1 type can bitrate 50000 # ip link set mxcan1 up # candump mxcan0 Loop back mxcan0 and mxcan1, open another terminal, and type # cansend mxcan1 1 2 3 -i 50 The caddump will display the following messages: # <0x032> [3] 01 02 03 5.3 Examples User may handle the CAN bus raw data by program. There are some examples in /moxa/mxcan/utility/examples. However the Moxa CAN bus driver is based on SocketCAN technology. User may refer to the Linux source document for detailed information. (linux/Documentation/networking/can.txt) ----------------------------------------------------------------------------- 6. Troubleshooting 6.1 Unable to restart the CAN interface If the CAN bus status is not in bus-off, the driver will not restart the interface. Check the bus state with the following command. # ip -detail link show mxcan0 3: mxcan0: mtu 16 qdisc pfifo_fast state UNKNOWN qlen 10 link/can can state BUS-OFF (berr-counter tx 0 rx 0) restart-ms 0 ^^^^^^^^^^^^^^^^^ 6.2 Installing the Moxa CAN Driver in Kernel 2.6.31 Linux Kernel has supported the SocketCAN device driver in the mainline since version 2.6.31. However, a decent version of iproute2 library should be installed for proper operation. Otherwise, you will encounter an error when you set bitrate to CAN interface. Some distributions don't install the suitable iproute2 as default. You can type the following command to check the version of iproute2. # ip -V ip utility, iproute2-ss091226 For earlier versions, such as ip utility, iproute2-ss090324, you will need to upgrade to iproute2-2.6.31 or the latest such as /Dwnload/ ip oute2-2.6.31 .art.bz2from the Cinux Kernel hreposiory, ehen bompile ald tnstall intinto tour sistribution.
