The kernel appears to see the CAN device is present, but as soon as I try to enable things via “ifconfig can0 up” or “ip link set can0 up”, the CAN driver locks up. Thanks, Marc. sh #!/bin/sh -x sudo ip link set can0 type can bitrate 500000 sudo ifconfig can0 up $ . But did not helped. To get the supported commands. I stripped down the program and it would be great if anybody could help me. Any other bitrate is not validated on Tegra MTTCAN driver. $ cat can_start. Temporarily change your CAN network speed by running sudo ip link set can0 down type can to drop the network and then sudo ip link set can0 up type can bitrate 1000000 to bring it back up with your new desired speed. Note that this is beta software and should be treated with caution - back up valuable data just in case. To stop the can0 interface: sudo ip link set can0 down type can. To confirm the network is back up and running at the correct speeds run ip -details -statistics link show can0 and look for the following: The UCCB adapter introduces itself as a serial device (/dev/ttyACM0) so it has to be set up as slcan device. 1 Release. sudo ip link set can0 down && sudo ip link set can0 type can bitrate 250000 && sudo ip link set can0 up.

On GNU/Linux, this can be accomplished using candump from the can-utils package as follows: Enter: #ip link set up can0. To set it to 1Mbit/s bitrate, invoke: ip link set can0 down; ip link set can0 type can bitrate 1000000; ip link set can0 up; Please note that the interface can be configured in the down state only. This case was reproduceable when the target devices are left disconnected for a while where the socket can device periodically tries to check the devices via sending a packet. To better understand the communication taking place in the following examples, you can monitor the CAN traffic from the host PC. This also resets the CAN device. root@zynq:~/test # ^C.

Reload to refresh your session. To set the device can0 to an arbitration bitrate of 500 kBit/s and a data bitrate of 4 MBit/s (for frames with bitrate switch flag): sudo ip link set can0 up type can bitrate 500000 dbitrate 4000000 fd on. On Baltos systems you have an embedded CAN interface called can0. py. down /sbin/ifconfig can0 down. This looks good to me, your device seems to support 1000kbit/s. -L 8: Sets the data length to 8 bytes. In this command, bitrate can be any valid CAN bitrate for stand CAN. To bring up the can0 interface. Set the output queue length to a value which is large enough to hold the messages of one cycle: sudo ip link set can0 txqueuelen 100 Setting the SocketBusOptions::sndBufLength_ to 1 (or any other small value > 0). root@zynq:~/test # ip link set can1 type can bitrate 125000. 6 is surprising, but I guess the lack of a Fixes: tag meant it slipped through the back-ports net. -I 18DA00F9: Sets the arbitration ID to 0x18DA00F9 (ID for diagnostics).
