| Post subject: | usb2can on Raspberry |
Hello I could not find any information on getting the usb2can to work on linux. My linux knowledge is very limited... The kernel is compiled with CAN support --- pi@raspberrypi ~ $ grep "CONFIG_CAN" /home/pi/workdir/linux/.config CONFIG_CAN=y CONFIG_CAN_RAW=y CONFIG_CAN_BCM=y CONFIG_CAN_GW=y # CONFIG_CAN_VCAN is not set CONFIG_CAN_SLCAN=y CONFIG_CAN_DEV=y CONFIG_CAN_CALC_BITTIMING=y # CONFIG_CAN_LEDS is not set # CONFIG_CAN_AT91 is not set # CONFIG_CAN_MCP251X is not set # CONFIG_CAN_FLEXCAN is not set # CONFIG_CAN_SJA1000 is not set # CONFIG_CAN_C_CAN is not set # CONFIG_CAN_CC770 is not set # CONFIG_CAN_EMS_USB is not set # CONFIG_CAN_ESD_USB2 is not set # CONFIG_CAN_KVASER_USB is not set CONFIG_CAN_PEAK_USB=y CONFIG_CAN_8DEV_USB=y # CONFIG_CAN_SOFTING is not set # CONFIG_CAN_DEBUG_DEVICES is not set --- (The peak driver is activated because Im testing this one too.) When I plug in the usb2can adapter it is recognized correctly --- [ 2.680102] usb 1-1: New USB device found, idVendor=0424, idProduct=9514 [ 2.688271] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 2.701367] hub 1-1:1.0: USB hub found [ 2.706675] hub 1-1:1.0: 5 ports detected [ 2.989777] usb 1-1.1: new high-speed USB device number 3 using dwc_otg [ 3.120181] usb 1-1.1: New USB device found, idVendor=0424, idProduct=ec00 [ 3.128535] usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 3.157279] smsc95xx v1.0.4 [ 3.225856] smsc95xx 1-1.1:1.0 eth0: register 'smsc95xx' at usb-bcm2708_usb-1.1, smsc95xx USB 2.0 Ethernet, b8:27:eb:1a:1c:45 [ 3.329978] usb 1-1.3: new full-speed USB device number 4 using dwc_otg [ 3.453475] usb 1-1.3: New USB device found, idVendor=0483, idProduct=1234 [ 3.469758] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 3.478624] usb 1-1.3: Product: USB2CAN converter [ 3.499704] usb 1-1.3: Manufacturer: edevices [ 3.505527] usb 1-1.3: SerialNumber: ED000216 [ 4.013058] udevd[156]: starting version 175 --- But how do I get further? ifconfig does not show a CAN device. So the SocketCAN that I want to use is not working. many thanks in advance. Greetings Klaus |

Many thanks, it works  Where is the best place to put a automatic bitrate setting after startup? I get messages in dmesg every second unless I enter 'sudo ip link set can1 type can bitrate 125000' Placing it in /etc/rc.local leads to a very slow system. Greetings Klaus |
