When I use MBD Toolbox's CAN examples, my devkit-5744p board couldn't receive or send messages through Kvaser after the code generated by the model was downloaded,none of CAN's examples can make it communicate properly. However, other examples such as ADC and FLEXPWM make my devkit-5744p work properly.Please tell me the reason.Thanks.
The CAN transceiver requires 12V power and it won't work when the board is powered over USB. Please give it a try by powering the board at 12V.
Hope this helps,
