Re: AW: AW: CAN Interface on Toradex Board

[Mirza Krak <mirza.krak@gmail.com>]

Hi.

I am also an user of Tegra 2 module from toradex and I haven't had any 
similar issues. Which eval board are you running? Have you tried the 
canconfig tool? Have you tried building iproute2 with the bitbake, this 
is what I have used without any issues. Don't know the state of the 
packages available for download.

And also why don't ask toradex support for this?

mvh
Mirza
