FNet communication

FNet is an BlueBox proprietary bus system and communication protocol that provides fast communication between devices connected to the same network and enables:

Fast communication between MCU and BlueBox

Network analysis

Synchronous debug and trace of multiple MCUs

Correlation of MCU events with network events.

 

 

This chapter will show you how to:

Configure the ADIO or CAN/LIN

Configure counters, triggers and events

Inject a CAN message

Provide SPI protocol description

 

 

FNet communication network

FNet communication network consists of devices, that are connected to FNet nodes with FNet cable.

 

fnet_network

 

Active Probes enable fast communication between MCU and the iC5700:

oInfineon DAP/DAPE connects to the DAP debug and DAPE trace interface

oInfineon AGBT connects to the Aurora GigaBit Trace (AGBT) interface

oARM HSSTP connects to ARM High-Speed Trace Port (HSSTP)

 

Network analyzers, add-on modules (AOMs) that capture network data:

oADIO, analog/digital/SPI analyzer

oCAN/LIN, CAN/CAN-FD/LIN analyzer

 

hmtoggle_arrow0 FNet communication is supported on iC5700 only.
hmtoggle_arrow0 Each iC5700 features 1 FNet port, which allows connection of 1 FNet device.
hmtoggle_arrow0 IOM6 Hub extends the iC5700 with 3 additional FNet ports and a FBridge port.
hmtoggle_arrow0 FBridge port connects to another IOM6 Hub on a second iC5700 for synchronous debug and trace.
