This would be used to get the chinese CAN Analyzer USB working with can-utils suite.

Go to your kernel sources folder and clone as submodule usb-can driver.

git submodule add https://github.com/V0lk3n/usb-can-2-module drivers/net/can/usb-can-2-module

Edit drivers/net/can/Kconfig and add the following line :

source "drivers/net/can/usb-can-2-module/Kconfig"

Edit drivers/net/can/Makefile and add the following line :

obj-y				+= usb-can-2-module/

In Section “Networking Support”

Under “CAN bus subsystem support —> CAN Device Drivers”

• Select as Module “hlcan module for usb-can”

Go to your kernel sources folder and clone as submodule can-isotp driver.

git submodule add https://github.com/V0lk3n/can-isotp drivers/net/can/can-isotp

Download “isotp.h” to “include/uapi/linux/can”

cd include/uapi/linux/can
wget https://raw.githubusercontent.com/v0lk3n/can-isotp/refs/heads/master/include/uapi/linux/can/isotp.h

Edit drivers/net/can/Kconfig and add the following line :

source "drivers/net/can/can-isotp/Kconfig"

Edit drivers/net/can/Makefile and add the following line :

obj-y				+= can-isotp/

In Section “Networking Support”

Under “CAN bus subsystem support —> CAN Device Drivers”

• Select as Module “CAN ISO 15765-2 driver”

This driver should be build as module! To get the ability to load it using sudo insmod elmcan.ko accept_flaky_uart=1 if needed.

This driver has become an official part of Linux since v6.0

In Section “Networking support”

Under " > CAN bus subsystem support > CAN Device Drivers —>"

• Select as module (<M>) Serial / USB serial ELM327 based OBD-II Interfaces (can327)

For Kernel 4.11 or higher. You can add ELM327 driver by following these step :

• Go to root of your Kernel repository and run these commands

git submodule add https://github.com/V0lk3n/elmcan drivers/net/can/elmcan
cp drivers/net/can/elmcan/can327.c drivers/net/can/

• Edit drivers/net/can/Makefile and add the following line.

obj-$(CONFIG_CAN_CAN327)	+= can327.o

• Edit drivers/net/can/Kconfig and add the following config.

config CAN_CAN327
	tristate "Serial / USB serial ELM327 based OBD-II Interfaces (can327)"
	depends on TTY
	select CAN_RX_OFFLOAD
	help
	  CAN driver for several 'low cost' OBD-II interfaces based on the
	  ELM327 OBD-II interpreter chip.

	  This is a best effort driver - the ELM327 interface was never
	  designed to be used as a standalone CAN interface. However, it can
	  still be used for simple request-response protocols (such as OBD II),
	  and to monitor broadcast messages on a bus (such as in a vehicle).

	  Please refer to the documentation for information on how to use it:
	  Documentation/networking/device_drivers/can/can327.rst

	  If this driver is built as a module, it will be called can327.

Finally, build the kernel.

Under “CAN bus subsystem support > CAN Device Drivers —>

• Select as module (<M>) Serial / USB serial ELM327 based OBD-II Interfaces (can327)

For Kernel lower than 4.11. You can add ELM327 driver by following these step :

• Go to root of your Kernel repository and run these commands

git submodule add -b linux-pre-4.11 https://github.com/V0lk3n/elmcan drivers/net/can/elmcan

• Edit drivers/net/can/Makefile and add the following line.

obj-y                           += elmcan/

Finally, build the kernel.
