CCS/TMS570LS20216: Hercules TMS570 MDK Kit Flexray to NI Flexray fail

Part Number: TMS570LS20216

Tool/software: Code Composer Studio

We have test  Herclues Flexray and use the development tool as below:
EVM: TMS570 MDK Kit Chip is TMS570LS20216 (

We test TI Hercules 4 nodes connection OK
TMS570 MDK Kit => Flexray cable => TMS570 MDK Kit

But connected to National Instruments NI-XNET PCI card is failed:
TMS570 MDK Kit => Flexray cable => NI Flexray NI-XNET PCI card ( )

Does anyone have a successful link Hercules Flexray to NI Flexray card?


  • Hello Andy,

    Nice to know you got 4 nodes (TI Hercules device) Flexray network work. We never tested with NI PCI card. Please check the configuration for NI PCI to make sure they match each other (number of static segments, dynamic segments, wakeup, number of coldstar, llength of the communication cycle, and timing parameters, etc).
