[yocto] CAN bus protocol error

[wuteng wu]

Hi, could you tell me how to clean and rebuild the kernel?
I'm newbie to yocto, i have done something like linux-menuconfig when i
used the build-root, bu which i can config the kernel configuration, but i
don't know how to do it in yocto, at least i didn't find any reference in
ref-manual.
