Rebuild Drivers for Ubuntu

Rebuild Drivers for Ubuntu

[Jeff Holtz]

I'm developing some ISOTP programs and would like to rebuild the drivers to
include the CAN-ISOTP.ko file for UBUNTU (currently using 14.04 LTS)  I can
get the code for the build for 14.04 which includes all the can, can-bcm,
can-raw ko's but nt the isotp.  I've git the can-modules but having
difficulties merging the latest code and where to place it to build.  Any
help/instructions would be appreciated.

for example:
   cp ~/can-modules /usr/src/linux-3-13.0/.
   make SUBDIR=drivers/net/can

Hello Jeff,

I would suggest the following:

Download the can-modules git from gitorious:

	git clone git://gitorious.org/linux-can/can-modules.git

	cd can-modules/net/can/

	make CONFIG_CAN=n CONFIG_CAN_RAW=n CONFIG_CAN_BCM=n CONFIG_CAN_GW=n

This should have created a can-isotp.ko which you can load with

	sudo insmod ./can-isotp.ko


# dmesg | tail -1
[  452.044371] can: isotp protocol (rev 20130731 alpha)

There's no need to compile the CAN mainline modules again.
You just need the linux-headers-<your-kernel-version> and the standard gcc
build environment (which was needed to compile can-utils anyway).

Please give me some feedback if it doesn't work as expected on your machine.

Regards,
Oliver

BRILLIANT!!

Thanks.  This worked.  I had tried to simply do a make and it wasn't

working.  Found the error since I am on Trusty 3.13 and PDE is no longer

valid (need to use PDE_DATA)
 

I'd love to figure out how to simply place can-modules into source and

rebuild everything but seeing as I have what I'm looking for now I'm good to

do.  THANKS AGAIN!!!
