Imx6DL sabre AI CAN testing

arunswarnam — Thu, 05 Mar 2015 13:33:59 GMT

I have ported linux onto IMX6Sabre Dual lite AI board. I wanted to test the CAN peripheral .As given in the linux reference manual I made the CAN0 link up using

"ip link set can0 up type can bitrate 500000"

Then i tried which ip , ifconfig .Everything worked fine

Then tried to send a CAN message using cansend can0 500#1E.10.10 .

But nothing is received on the other side (I have an arduino with a CAN shield operating at 500Kbps whose CAN L and CAN H are connected to the imx6 base board CAN1 connector).

Any suggestions on how to make this work ?

Thanks for the rreply igorpadykov. But when I try to set my can1 up (ip link set can1 up type can bitrate 125000) . It says "Cannot find device "can1" ".

suggest to check linux configuration with i.MX_6Solo6DualLite_Linux_Reference_Manual.pdf

document sect.33.1.4 Linux Menu Configuration Options from Doc package L3.0.35_4.1.0_LINUX_DOCS

also please use BSP from Sabre - AI product page

SABRE|Automotive-Infotainment|i.MX6|Freescale !

L3.0.35_4.1.0_ER_SOURCE_BSP
