CAN-Bus extensions

The Eclipse Leda quickstart image has CAN-Bus kernel modules and some CAN hardware drivers pre-installed. However, some hardware configuration needs to be adapted at boot time depending on the specific CAN-Extension being attached to the device.

On Raspberry Pi, there is a /boot/config.txt file where you can configure the dtoverlay options accordingly.

Note: After modification, the device requires rebooting for the changes to take effect.
