Hi,

    I'm trying to get flexcan send and receive working using a MPC5748G-GW-RDB board. I used the flexcan_mpc5748g example project, set up CAN settings, and generated code using processor expert. I am unable to see any CAN data that I send. I have attached my project and screenshots of my CAN configuration below. Please let me know what is wrong in my project. 

Thanks,

Hi,

on the MPC5748G-GW-RDB you need to enable peripheral supply (5V0_SR) which is OFF by default.

As per schematic PD12/GPIO60 pin must be set to output and set high.

PB0/PB1 and PC10/PC11 are connected to TJA1044 so no further control pins are needed, as it is for TJA1043.

I can recommend to download the board's Quick Start Package from https://www.nxp.com/design/development-boards/automotive-development-platforms/mpc57xx-mcu-platforms... 

It includes a lot of guides, examples for this board.

BR, Petr
