TMS570 CAN loopback testing

Other Parts Discussed in Thread: TMS570LS3137

Hi,

I'm trying to test loopback mode in TMS570LS3137 device. I have enabled test mode in CTL, LBack in Test register, configured one mailbox in CAN1 for sending a message and another mailbox in CAN1 ro receive a message. I have set a breakpoint in ISR but the breakpoint is never hit. I monitored CAN TX pin on Osci. There is no activity after sending a message. Could you let me know what else to do for loopback testing?

Thanks and Regards,

Vishwanath Reddy.
