S32M276SFFRD- CAN Communication

Bravin_Link — Mon, 21 Oct 2024 21:05:42 GMT

Hello,

I have received a S32M276SFFRD evaluation board and need to get CAN working on it. See the attached .zip file for the board details. I am following the approach of using the s32m27x_can_receive_s32ct example that is included within NXP_MBDToolbox_S32M2xx. This example can be found under this path: C:\Users\username\AppData\Roaming\MathWorks\MATLAB Add-Ons\Toolboxes\NXP_MBDToolbox_S32M2xx\S32M2_Examples\can and includes a Simulink file that relies on the S32 Configuration Tool to configure the board settings. I have already been successful with interacting with the boards built in RGB LED but am struggling with getting CAN to either be transmitted or received. I have a VN5620 Vector case that I am using to hook up to the CAN H and CAN L header pins on the board to either send or receive messages on the bus. If I understand correctly there is a CAN PHY built into the microchip already, so I don't need to configure pins such as PTB0 and PTB1 as CAN rx and CAN tx. I would expect the example project to work on the evaluation board without any issue but have had no luck so far.

I have made sure that there is 120 ohm resistance on each end of the bus. I have verified that the baud rates on both the board and the VN5620 CAN case are the same. I have probed out the pins from the microchip to the headers to the pins on the Vector CAN case to prove there is continuity through the CAN H and CAN L lines.

Can you help me out with this issue? Please let me know of any additional information that is needed.
