UJA1169 TRANSCEIVER

Hi ,

I'm trying to run the project example FlexCAN on the S32K DESIGN STUDIO with no success.

I suspect the culprit is UJA1169 Transceiver. This project originally uses a different Transceiver.

However I modified it to use the UJA1169 .

But it is not working for me .

I 'm pretty certain that I connected the boards and all the jumpers are set properly however I'm not a %100 sure.

CAN_HI/LO to CAN_HI/LO and Ground to Ground  and jumpers j109/j108 are at default 1-2 position to insert the termination. THE BOARDS ARE POWERED VIA micro USB connector .

But I can't see anything on the scope on TX/RX CAN_HI/CAN_LO and it is not toggling the LEDS as it is supposed to.

When I choose the loop back mode for the CAN, it works

The project is attached.

 

Thanks,

Koorosh Hajiani
