can error missing /usr/lib/ip/link_can.so

admin — Wed, 11 Dec 2013 09:49:08 GMT

Hello

Im trying get socketcan up and running on imx28 using

freescale-community package for yocto. I have included, libsocketcan, canutils and iproute2 as recepies in my build.

Calling:

strace ip link set can0 type can bitrate 125000

if end with: open("/usr/lib/ip/link_can.so", O_RDONLY|O_CLOEXEC) = -1

ENOENT (No such file or directory)

I can see from the mailing liste that older advise is to use a newer

version of iproute2, but i can not see that version iproute 3.10 helps

me.

Can any point me i a direction that may bring socketcan up and running on imx28?

more detailed information:

Currently i am using the default linux 2.6.25-3 that is in long term

maintenance from freescale.

I use http://layers.openembedded.org/layerindex/recipe/21569/ i.e.

iproute2 3.10.0.

ip -V on target replies:

root@imx28evk:~# ip -V

ip utility, iproute2-ss130716

so im fairly sure that im not being hit by and old busybox version.

ifconfig -a gives me:

can0 Link encap:UNSPEC HWaddr

in /sys i have:

root@imx28evk:/sys# find . -name *can*

./devices/virtual/net/can0

./devices/virtual/net/can1

./class/net/can0

./class/net/can1

./kernel/slab/can_receiver

./module/scsi_mod/parameters/scan

./module/can

kernel options enables for can

CONFIG_CAN_DEBUG_DEVICES=Y

CONFIG_CAN_FLEXCAN=Y

CONFIG_CAN=y

CONFIG_CAN_RAW=y

CONFIG_CAN_CALC_BITTIMING=Y

CONFIG_CAN_DEV=Y

I hope this gives knowledgeble persons enough to help me troubleshoot

this problem.

Best

Jens

Hi Jens,

Have you tried with cantest? I have used it with LTIB and I have not got any issue.

I do not know if that fulfills your requirements. But let me try with socketcan and yocto.

I will let you know if I find something useful.

Best Regars,

Alejandro
