Introduction

The Gateway Demo package consists of all demos related to Automotive Gateway for J721E family of devices . These demos use AUTOSAR compliant drivers. At present only CAN-Ethernet Gateway demo is part of the package.

Getting Started

What's New

Module Changes Over Previous Release
CAN-Eth Gateway Demo
  • Support for CPSW9G driver has been added and support for CPSW2G has been deprecated
  • Support for Eth-to-Eth routing has been added since the demo now supports two Ethernet ports
  • Demo application runs on MCU 2_1 on Main domain and support for MCU domain has been deprecated
  • Main domain MCANs (MCAN4 and MCAN9) are used instead of MCU domain MCANs
  • There is an additional dependency to run Ethernet Firmware on MCU 2_0
  • Automated test setup to run all four routes (CAN-to-CAN, CAN-to-Eth, Eth-to-Eth and Eth-to-CAN) and report test results
  • The HW setup now requires an additional GESI card in addition to J721E EVM

Device Support

SoC HOST (OS) Target (OS) Test Platform
J721E Linux TI RTOS J721E EVM + GESI card

Validation Information

This release was built and validated using the following tools.

Build Tools (included in Processor SDK):

Fixed Issues

ID Description Module
NA NA CAN-Eth Gateway

Known Issues

ID Description Workaround Comments Module
ADASVISION-3729 Test tool reports high Max latency (milliseconds) occassionally for Eth-to-CAN routing Run at a lower inter packet gap and fewer number of packets Not a major issue, does not affect routing as average latency is still low. CAN-Eth Gateway
ADASVISION-3961 Unexplained packet drop for Ethernet to CAN routing NA Suspected to be a queue overflow issue, but not root caused. CAN-Eth Gateway

Known Limitations

ID Description Workaround Comments Module
ADASVISION-3962 Implement polling mode for CAN to reduce average and min latencies Run at a lower inter packet gap and fewer number of packets This results in high latencies for CAN to CAN routing. Use workaround to see actual latencies or do manual routing CAN-Eth Gateway

Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit Meaning Description
1 (M=Major) Major revision Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor) Minor revision Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch) Patch number Incremented for all other source code changes. This include any packaging support code.
4 (b=build) Build number Incremented for each release delivery to CM. Reset for any change to M, m or p
