I'm currently working on i.MX28 with a linux kernel generated by Yocto project.
I noticed that I can activate some functionnalities of kernel with this specific config file :
For example, I've changed
# CONFIG_CAN_BCM is not set
I recompile linux kernel with following command
bitbake -C fetch virtual/kernel
and it activates BCM protocol for CAN bus.
I would like to know if it is possible to add this BCM protocol without recompiling all kernel.
I've heard kernel modules could do that, but I'm totally novice to that.
Thank you in advance if you could help me.
