MPC5748G-GW-RDB CAN communication with Vector CANoe not working using default sample code

[hims8111]

Hi All,

I am facing issue in CAN/flexCAN communication between MPC5748G-GW board and Vector CANoe. I have referred many posts on this stating sample code for MPC5748G DEVKIT but not sure about MPC5748G-GW board. I also verified bit timing setting on both as described below but still no luck. If someone can share test example covering successful CAN communication between Vector CANoe and MPC5748G-GW board would be highly appreciated.

MPC5748G- Bit time setting in Component Inspector Window:

Clock source : PE Clock (40MHz), Arb Bit Rate :500Kbps, Sampling Point : 62.5%, PropSeg=0, PhaseSeg1=7, PhaseSeg2=5, Pre-scaler=4, SJW=2

CANoe side-Bit time setting in Hardware setting window:

Clock source=80MHz, Arb Bit Rate :500Kbps, Sampling Point : 62.5%, TSeg1=4, Tseg2=3, Pre-scaler=20, SJW=2

Thanks

Hi,

on this board you need to enable peripheral power supply setting PD12 high. Also if using TJA1043 transceivers enable it too. You can refer to MPC5748G-GW-RDB_ExampleCodes-UserGuide.pdf which is part of 3) MPC5748G-GW-RDB Quick Start Package.

BR, Petr

Hi PetrS,

Thanks I was already following the QSG document. I thought its bit time setting issue but I misinterpreted CAN channel numbering from cable schematics. According to CAN harness schematic VIEW A, P1-P2 (CAN 0) is starting from extreme right from front side. However, I misinterpreted from back side. I confirmed the CAN communication, its working now.
