Other Parts Discussed in Thread: AM3517

Hİ,

I have TAM3517 System on Module (TI Sitara AM3517 @ 600Mhz) and i have installed angstrom distribution on it.

I got everything works perfect except can bus.

I tried several things and i got some example below and i typed it in linux terminal

1) modprobe can-raw
2) modprobe ti_hecc
3) ip link set can0 type can bitrate 250000
4) ip link set can0 up					
5) ip link set can0 down

But the problem is my linux is not recognize the "modeprobe" command. Is there anyother way to

get can bus working or what can i do to solve this problem ?

Thanks Anil,

Is that mean i have to compile kernel again? or can i do this configuration with my current system?

And one more thing, Could it be because of my kernel version? it is 2.6.39.

Hakan,

You can look at the kernel configuration whether the kernel you are using have the CAN enable or NOT.

This can be done by (after kernel boots up)

$ zcat /proc/config.gz | grep HECC

If you see any flags related to HECC is saying "set" then by default kernel have HECC driver so no need to do "modprobe"

Otherwise (it says not set) then you have to rebuild the kernel with the configuration specified in the user guide.
