AM2634: Need to know about CAN transceiver IC mentioned in AM2634 EVM board.

Hitesh,

Only MCAN1 is connected to the TCAN1042 (U20). MCAN0 and MCAN2 are not connected to a CAN transceiver, and thus there is no hardware convert the single-ended logic used by the AM2634 to the differential signal transmitted over the CAN bus.

Hi Brennan,

I am aware of that MCAN0 and MCAN2 are not connected to a CAN transceiver internally and only MCAN1 is connected.
Thus I have used external TCAN1042 hardware to connet with MCAN0 or MCAN2.
I am using the same circuit externally which is there in internally on AM2634 EVM board. Please ref the above circuit which I am using externally.

Hello Hitesh,

I presume you are using this EVM? https://www.ti.com/tool/TCAN1042DEVM

If so can you take an image of how you are wiring into that EVM? I want to review your connections and jumper configurations.

Best Regards,

Ralph,

I am not using TCAN1042DEVM hardware module. I am using below breadboard circuit ( Schematic is taken from TI AM2634 EVM module)
Please refere the below wiring diagram that I am using as external CAN transceiver.
