Part Number: TMS570LS20216

Tool/software: Code Composer Studio

Hi,

    I want to run "Media:FlexRay_Communication_CCSv5.zip" flexray demo code on 2 TMS570LS20216 HDK development kits ,one  as "node A"，

and the other  as "node B"。

   The problem is  I dont know how to connect the FlexRay terminals together.weather bothe  the FlexRay1 terminals should be connected or else. 

and I cant  find any documents to tell the way how to use the development kits with demo code,for example "which node sends what data to which node ,and what the het1 and het31 led stands for."

    Hello Cheng,

    The flexray node consists of a controller and an external driver or transceiver. The controller includes the host CPU (for example LS20216) and FlexRay communication controller (CC, integrated in LS2x MCU)). The driver includes bus drivers (BD) and bus guardians (BG). The bus driver changes structure based on the bus guardian, which is an optional component for a FlexRay node.

    This is the connection between MCU and the bus driver:

    This is the node interface to the Flexray bus (BP to BP, BM to BM):
