Hi am using IMX28 EVK and its linux 2.6.35 BSP

I am having problems in configuring can interface.

In ltib package list i enabled can4linux and cantest

-- Package Selection

Package List -->

[*] cantest

[*] can4linux

In kernel configuration

[*] Networking support --->

<*> CAN bus subsystem support --->

<*> Raw CAN Protocol (raw access with CAN-ID filtering)

<*> Broadcast Manager CAN Protocol (with content filtering)

CAN Device Drivers --->

<*> Virtual Local CAN Interface (vcan)

<*> Platform CAN drivers with Netlink support

[*] CAN bit-timing calculation

<*> Microchip MCP251x SPI CAN controllers

<*> Philips/NXP SJA1000 devices --->

CAN USB interfaces --->

[*] CAN devices debugging messages

<*> Freescale FlexCAN

But when i issue the commands like

$ ip link set can0 up type can bitrate 500000

Cannot find device "can0"

$ ifconfig can0 up

ifconfig: SIOCGIFFLAGS: No such device

What will be the problem???
