Hi,

In AM335x TRM ( spruh73j.pdf) CAN message transfer (Normal mode ) is explained well.

But how is the CAN message transfer in Loop back mode ?

Can any one help on this ? or provide sample Loop back code ?

Regards,

TRM section 23.3.8.3.2 describes CAN loopback mode. To enter this mode you must set bit 4 (LBack) of the CAN TEST register to 1. Other than this there is no difference from normal mode, except that you will receive only the messages you send.
