Introduction
This release notes provides important information that will assist you in using the EthFw component. This document provides the product information and known issues with respect to EthFw software component. The EthFw component consists of firmware for Ethernet switch, profiling tools and demos/applications for J721E, J7200 and J784S4 silicon platforms.
Licensing
Refer to Processor SDK RTOS top-level manifest.
Getting Started
The Ethernet Firmware User's Guide provides the documentation and references necessary to run EthFw demos and begin development on TI's platforms.
Documentation
Refer to following documentation for further details:
| Ethernet Firmware User Guide | Build instructions, Demos | [HTML] |
| Ethernet Firmware API Guide | API Guide | [HTML] |
What's New
- Scatter-gather support for packet transmission. Refer to ENET section in PDK User's Guide for porting information.
- TCP/UDP hardware checksum offload.
- XAUI (2.5Gbps), USXGMII (5Gbps and 10Gbps) support at driver level.
- MDIO CDC errata (i2329) workaround implementation.
Upgrade and Compatibility Information
Users moving from SDK 8.2 or older to SDK 8.4/8.5 must refer to the Porting Guide document which describes how the board initialization routines have been restructured.
Device Support
Below table shows device support for EthFw.| SoC | HOST (OS) | Target (OS) | Test Platform |
| J721E | Linux | FreeRTOS | J721E EVM with GESI and QSGMII Daughter Boards |
| J7200 | Linux | FreeRTOS | J7200 EVM with QSGMII Daughter Board |

Refer Processor SDK RTOS RTOS release notes for SDK device support.
Validation Information
This release was built and validated using the following tools. Refer to the EthFw User's Guide for additional instructions to install and setup the dependencies.Build Tools (included in Processor SDK)
- TI ARM CLANG: 1.3.0.LTS
- FreeRTOS Kernel: 10.4.3
- lwIP stack: 2.1.2
Fixed Issues
| Issue ID | Head Line | Module | Affected Platforms | Reported in Release | Fixed in Release |
| ETHFW-2064 | mdio: Manual mode emulation may result in infinite loop | ENET | J7200 | 08.04.02.00 | 08.05.00.00 |
| ETHFW-2028 | EthFw: j7200: QSGMII PHY reg read/write may fail at boot time | EthFw | J721E, J7200 | 08.04.00.00 | 08.05.00.00 |
| ETHFW-2029 | Enet: SGMII TX/RX not enabled at 100Mbps | ENET | J721E, J7200 | 08.04.00.00 | 08.05.00.00 |
Known Issues and Limitations
| Issue ID | Head Line | Module | Reported in Release | Affected Platforms | Workaround in this release |
| ETHFW-1580 | [EthFw] EthFw server app + Linux - I2C access failure | EthFw | 07.01.00.00 | J721E, J7200, J784S4 | EthFw should avoid any I2C operations from Main R5F core to prevent conflicts with A72 or other core from happening. Static MAC address pool can be used instead of dynamically populating from EEPROM. |
| ETHFW-2023 | Cable connect/disconnect can cause CPSW unrecoverable condition | ENET, EthFw | 08.00.00.00 | J721E, J7200, J784S4 | None |
| ETHFW-2084 | Assertion from EnetMcm_coreAttach() | ENET, EthFw | 08.01.00.00 | J721E, J7200, J784S4 | None |
| ETHFW-2083 | Documentation: Traceability matrix not generated for SDK 8.5 | Documentation | 08.05.00.00 | J721E,J7200, J784S4 | None. |
Dependencies
All Ethernet Firmware dependencies are also part of the SDK, please refer to the User's Guide for details.

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. |
