It was unlikely in the past that a PC or embedded device was equipped with different CAN controllers. Instead the new version has to be compiled for the target hardware.

The following instructions present all steps requiered to build a kernel with the correct modules, and some useful commands to czn it. I know from experience It is usually necessary to change the device access rights set by udev.
linux DRIVER of mcp2515
The Third message will then go into Buffer 0, and on the next interrupt it will read the third message out of Buffer 0 and cwn the second one out of Buffer 1. It was unlikely in the past that a PC or embedded device was equipped with different CAN controllers.
You first read the interrupt status register, interpret the data, then read the buffer again via SPI It started already in and is now considered as mature. This design was chosen to improve the performance of this special can4linux version. This above mentioned full flexibility is not ,inux in embedded applications. That means especially that only one CAN controller support with a special register access method is compiled into the driver.

CAN bus Linux driver
It was possible to use different kinds of boards at the same time. CAN bus is a communication protocol used mainly in cars and some industrial products. Haven’t received registration validation E-mail? My can controller is mcp, SOC is s3c, and based on linux kernel version is 2.

It is possible to do it directly without using a temporary build directory, but this method has the advantage of being possible on a remote machine, and to allow easier save of the binary generated simply archive this directory if limux need to give it to someone else. Then return to the linux directory, to compile the kernel modules, and copy them to the build directory.
It has a rather obvious to me problem, which is similar, but worse than the one I warned about here: To use the 3. The Raspbian kernel doesn’t come with modules mmcp2515, so the kernel must be compiled from source. The standard MCPx has some drawbacks with kernel 3.

For initially writing these sysctl entries after loading the driver or at any time a shell script utility does exist.
This can be reduced using the following patch. I’m curious what are your goals?
