Subbu, You need to enable the CAN subsystem in the Linux kernel:
CONFIG_CAN=y (or m if you prefer a module) CONFIG_NET=y must be enabled for this (but is by default). You did not specify if you are using a particular CAN hardware that supports socket CAN. If so you need to enable the driver for that too. For example, a popular one is USB Peak CAN: CONFIG_CAN_PEAK_USB. Or if you want to use a virtual CAN interface CONFIG_CAN_VCAN=y You can change kernel configuration parameters for testing with: bitbake -c menuconfig virtual/kernel which will open the menu configuration for the kernel your Yocto build is using. :rjs On Thu, Sep 21, 2017 at 3:11 PM, Subramanian Ramachandran < sramachand...@agjunction.com> wrote: > Hi Yocto Team, > > > > I am using a custom Yocto linux distribution for my project and am > interested in implementing socket can support for it. > > > > I understand that socketcan is a kernel feature and needs to be included > at build time while using the bitbake/toaster toolset. > > > > The default yocto distribution of Krogoth I used does not contain > socketcan by default.
