2.3.3. Upgrade and Compatibility¶
2.3.3.1. FreeRTOS¶
- FreeRTOS is not supported on A72 core.
- FreeRTOS support is availble on all other cores. ( R5F )
- FreeRTOS Real-time Object View (ROV) in CCS IDE is available for R5F cores.
See FreeRTOS Chapter for more details.
2.3.3.2. TI-RTOS(SysBIOS)¶
- TI-RTOS(SysBIOS) is not supported on any cores from this release.
- RTOS support on A72 is also descoped.
2.3.3.3. NDK¶
- TI’s NDK TCP/IP stack is no longer supported on any cores.
- lwIP is now the only TCP/IP stack supported in this release.
2.3.3.4. OSAL¶
Following OSAL APIs which supported only TI-RTOS(SysBIOS) are descoped in this release.
- EventP
- EventP_pend()
- Migrate to similar API EventP_wait() which is supported for FreeRTOS
- QueueP
Descoped API Alternative API Osal_Queue_Handle QueueP_Handle Osal_Queue_Elem QueueP_Elem Osal_Queue_construct + Osal_Queue_handle QueueP_create Osal_Queue_put QueueP_put Osal_Queue_get QueueP_get Osal_Queue_empty QueueP_isEmpty
2.3.3.5. TI-CLANG¶
- This release introduces TI ARM Clang tool-chain/compiler for MCU R5 cores
- PDK drivers/examples are migrated from TI ARM CGT and validated with TI ARM Clang tool-chain.
- Note: TI ARM Clang tool chain generated code/binary size is more than that of TI ARM CGT.
See TI ARM CLANG Usage and Migration Guidelines Chapter for more details.
2.3.3.6. LPM¶
- LPM library provides a means on J7200 to move between Active mode and IO Retention mode.
- Scope would be to implement a Low Power Manager (LPM) running on MCU R5 core, with APIs to switch to and from IO Retention mode to ACTIVE mode on J7200 device with dual Leo + Hera PDN.
- When we come back from IO Retention to ACTIVE mode, programs can be executed on all other active cores.
- See LPM Chapter for more details.

2.3.10. Limitations¶
2.3.10.1. PDK¶
- PDK examples do not support SMP mode. Some of examples still support build in SMP mode but these binaries are not supported or validated.
- TI Clang compiler does not enable O3 optimization level and Thumb2 mode which were enabled by default with TI ARM CGT compiler. This has an impact on driver throughput. E.g. Ethernet performance has reduced by ~20% on J7200
- C++ build is not supported in this release for TI Clang compiler. It will be added back in next release.
2.3.10.2. ENET¶
- lwIP stack integration doesn’t support checksum hardware-offload feature.
