4.1.3. Upgrade and Compatibility

In this section, we only highlight a few significant changes in this SDK. For full list of upgrade and compatibility topics, please refer to individual components release notes SDK Components. Gateway Demos

Gateway Demos are no longer included in the PSDK package starting in 08.01.00 release. TI Arm Clang C/C++ Compiler

08.01.00 was the first release which includes TI Arm Clang Compiler (tiarmclang) for the R5F cores. Prior releases used the TI Arm Compiler (armcl). There are migration steps that may be necessary for existing code running on the R5F cores. The software delivered on R5F from TI has aleady been migrated accordingly. Please review the PDK release notes (LINK) for additional links and developer pages dedicated Clang migration. TI-RTOS vs. FreeRTOS

FreeRTOS is the default OS for R5F libraries and binaries starting in 08.00.00 release. In 08.01.00 release, FreeRTOS is the default build and TI-RTOS (Sysbios) is no longer supported or packaged as part of the SDK. Please review the PDK release notes (LINK) for additional links and developer pages dedicated FreeRTOS migration. Enet LLD

Support for scatter-gather in packet transmission has been added starting in 08.05.00 release. This feature requires a change in Enet LLD DMA API, so applications using Enet LLD APIs need to be ported to use the updated API. Developers should refer to the porting steps documented in Enet LLD User’s Guide (LINK). NDK vs. lwIP

lwIP is the default network stack starting in 08.00.00 release. In 08.01.00 release, NDK was no longer supported or packaged as part of the SDK. MCU Software (MCUSW) Ethernet

MCAL Ethernet (MCU CPSW_2G) and Virtual MAC (virtual client for CPSW9G) drivers have been signficantly refactored to remove most dependencies with other SDK components, such as Enet LLD and UDMA LLD. The only remaining SDK dependency is with SCI Client driver. The driver configuration has also moved to a static-oriented allocation approach for TX channel, RX channel, Ring Accs, and other resources. Please refer to the Ethernet User Guide (LINK) chapter in the MCUSW documentation for further information about Ethernet module configuration.

Additionally, MCAL Ethernet driver (MCU CPSW_2G) now has Global Time support (packet timestamping) as well as support for link time and post-build configuration, in addition to pre-compile variant already supported in previous SDKs.
