canbus does not work because of iproute2

ozcanhakanzi

Hi everyone,

I have made my own filesystem with buildroot. When i config buildroot, i selected iproute2 support and can-utils.

But, when i type

"ip link set can0 type can bitrate 125000 "

this command gives below output

"ip: either dev is duplicate, or "type" is garbage "

Then i type "ip -V" to check iproute2 it gives

"BusyBox v1.19.3 (2012-02-16 14:41:41 EET) multi-call binary

Usage: ip [OPTIONS] {address | route | link | tunnel | rule } {COMMAND}

ip [OPTIONS] OBJECT {COMMAND}

where OBJECT := {address | route | link | tunnel | rule }

OPTIONS := {-f [amily] {inet | inet6 | link } -o[neline] }

but it has to show this output instead of the output above;

ip utility, iproute2-ss090324

What should i do to enable/configure canbus ?

Thanks in advance,

Hi Hakan,

1. Check the ip utility whether it's support can or not?

If not use latest iproute2 utilities.

2. For building the ip utility follow the steps mentioned at http://processors.wiki.ti.com/index.php/DCAN_Driver_Guide#CAN_Utilities

3. Copy ip utility to target filesystem under /sbin/. and rename to /sbin/ip.route2

Thanks Anil,

I just deleted the /bin/ip and it works. I think the device first look at the /bin folder and if "ip" doesn't exist then

the device use /sbin/ip and this is works for me
