[Buildroot] Request for Help

[BertHuber]

Hello,
I am new to this mailinglist and also quite new to the buildroot
environment.
I got stuck in my current project with the following problem:
 
I am currently trying to build an embedded Linux System with Buildroot. 

It works so far, I get a bootable SD Card for my A20 based board. 

I included all CAN Drivers & protocols I could find (can, can_raw and vcan) 

My problem is : after booting and loggin in as root

I type:

 ip link add dev vcan0 type vcan ---- THAT WORKS



but

 ip link add dev can0 type can 



produces:

RTNETLIINK answers: Operation not supported

What is wrong ?? Thanks in advance for any ideas.

Regards

Bert

Maybe your kernel is missing can support?

I don't beleive so, as I said, I selected every configuration item that has
anything to do
with CAN, also I explicitly selected the A20 CAN Driver in the Kernel.

Right,

maybe an issue with iproute, are you using busybox one, or the real one,
from 'ip tools' package?

AFAIK bbox ip does not support can. I might be wrong too.

I don't know. As I said I'm quite new to the whole Buildroot world.
How can I find out ? .. and if it is the wrong how do I install the right ?

Ok, so you go under Target Packages -> Networking Applications -> iproute2

Check it and do a rebuild. It will install legacy ip and tc tools.

[BertHuber]

Thank you. I did this and recognized that iproute2 was already selected.
So that means I already have the correct Version on my target system ?

Yes, its enabled then.

Well, I guess driver didnt detect your canbus.

Could you confirm if can0 can be added by:

ip link set can0 type can bitrate "you can bitrate here without quotes"


also, vcan0 is a virtual can interface, not the native one.
