Enabling UDP multicast with multiple network interfaces

If your computing unit provides several network interfaces, it is recommended to specify the route to the UDP multicast network:

sudo route add 225.0.0.0/24 dev eno1

where eno1 is the network interface that shall be used by odsupercomponent.

Setting up Peak CAN device in Linux

To use the Peak CAN device with OpenDaVINCI and OpenDLV, it is important to disable the NETDEV support (cf. http://www.peak-system.com/fileadmin/media/linux/index.htm):

make clean; make NET=NETDEV_SUPPORT; make install

Next, it is required to define the correct bitrate (https://www.peak-system.com/fileadmin/media/linux/files/Installation-en_ab6.9.pdf). To set the bitrate to 250k Baud run

ip link set can0 type can bitrate 250000

To check that the setting was applied successfully run

ip -details link show can0

Also the file /proc/pcan can be checked to confirm that the column ndev says can0 and the column btr says 0x11c (which represents 250k).

Unloading the device driver:

rmmod pcan

Loading the device driver:

modprobe pcan
