can bus - CAN loopback test

Question

I have a CAN transceivers in my J7 based embedded board. I am testing the loopback mode. I am using "cansend" & "candump" utility to send & receive the message. could you please take a look on my log and see if you can point any error. This is the frame I am sending. I see the CAN ID in output but no data.

cansend can0 001#1122334455667788
interface = can0, family = 29, type = 3, proto = 1
<0x001> [1] 01 
<0x001> [1] 01 

Please let me know what could I be missing here. Let me know if you need any other information.

Thanks, Satish
