2.1.3. Upgrade and Compatibility¶
2.1.3.1. FreeRTOS¶
- By default all the tasks will be created with floating point context enabled; i.e, save/restore of FPU Registers will be performed during each task switch.
- Until last release, this was not enabled and any task that required floating point hardware had to call portTASK_USES_FLOATING_POINT.
For more details, refer Task FPU context

2.1.10. Limitations¶
2.1.10.1. 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
2.1.10.2. ENET¶
- lwIP stack integration doesn’t support checksum hardware-offload feature.
