No CAN transmission without loopback in SPC5 studio with SPC58xGxx board

In SPC5 Studio, I have an example of CAN communication using the SPC58xGxx board. When loopback mode is enabled, the transmission works correctly. However, when I disable loopback mode, the transmission fails.

Could you provide guidance on how to successfully transmit CAN messages without using loopback mode? Additionally, I would like to know how to monitor the CAN signals using Peak-CAN.

Hi jmary,

I was setting wrong clock configurations because our board is different.
If you want to work CAN with NO LOOPBACK, configure your clock according to your board.

It may work, I solved the problem in similar way.

yes, I already found the solution also. correct, the bitrate not match between the device and the usb-can converter I use.
