I can't run the Flexray_Demo sample code with 2 nodes,some error interrupts were generated.Could you post the sample code described in the FlexRay Transfer Unit (FTU) Setup.pdf?Thank you.

    Hi,

    As I mentioned earlier, In a FlexRay cluster consisting of two nodes, both nodes must be coldstart nodes. At least two fault-free coldstart nodes are necessary for the cluster to startup. Please ensure that two nodes are startup at the same time.

    FlexRay buses require termination at the ends, in the form of a resistor connected between the pair of signal wires. Termination is one of the most frequent causes of frustration when connecting a FlexRay node to a test setup. Please double check if the termination resistors are populated on your boards.
