Does anybody managed CAN networking with TRK-MPC6534M EVB?

Hello,

 

I can't get CAN to work. The board has a MPC5634m + SBC 33903 for CAN communication.

I've powered the board with 12V, supply source is is to SBC, SBC is in DBG mode, there is 5V on 5V-CAN pin of the SBS.

The board is terminated (60-Split-60) and I connected an PEAK CAN-USB on the other side that I terminated as well with 120Ohm.

 

I've used the sample application from the cookbook (100kb/s) for the MCU, but the ESR register is indicating BUS OFF.

This is working in loopback mode.

 

The only signal I see on the CAN_A_Tx pin is the atteched one (blue trace), which I think correspond to BUS ERROR recovery, isn't it?

 

Thanks for your help.

Freescale Tech support solved it. The SBC needs to be configured via SPI to turn the transceiver on (even in debug mode).
