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:

./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
