TMS570LS04x HDK Demos



Hello,

I just received this board and am able to successfully run all demos except for the CAN reader. I am sending messages via PCAN but see no activity on the screen. The SCIRX and TX lights are flashing but no CAN messages are received. I have used both DCAN 1 and DCAN2 and have also tried connecting ground and not connecting it.

I do have a 120 Ohm resistor across CANH and CANL, and PCAN does not give me any bus errors. Can someone help me debug?

Lastly, the Port Reset button seems to do nothing. There is no feedback when pressing it, it almost feels stuck and the safety demo software never recognizes when i press it. Do i have a defective unit?

Please advise.

Regards,

Adam Ambriz
