Re: canbus interface issue on imx536

["Simone" <cjb.sw.nospam@gmail.com>]

Hello Daiane,
thanks for your reply.
I have checked and my configuration already have package iproute2.
I've checked in defconfig and all config related to FLEXCAN are setted to
"yes"
I don't know where to look.

There are someone with can experience on imx5?

Thanks so much!

I *almost* remember something regarding the package iproute2 and can. Do you
have this package into your image? Could you, please take a look on this?

Do you know if you need to re-configure buxybox to include some can support?

I'm sorry, I don't have any experience with can.... all my mental links are
from what I heard from imx-community threads.
