- Attention
- Also refer to individual module pages for more details on each feature, unsupported features, important usage guidelines.
- Note
- The examples will show usage of SW modules and APIs on a specific CPU instance and OS combination.
Unless noted otherwise, the SW modules would work in both FreeRTOS and NORTOS environment.
Unless noted otherwise, the SW modules would work on any of the CPU present on the SOC.
Unless noted otherwise, the SW modules would work on all supported EVMs

Limitations
| Head Line | Module | Reported in Release | Applicable Devices | Workaround |
| In BOM optimized mode, the current firmware doesn't give sufficient settling time for the 1.2V RF LDO. As a result, the 1.2V RF LDO is not settled before burst start. | General | 5.01.00.03 | xWRL6432 | Refer the known issues section in DFP release notes. |
| All the TLV's cannot be enabled at same time due to limitation of UART baudrate | Motion and Presence detection OOB demo | 5.01.00.03 | xWRL6432 | Enable only required TLV's |
| On-board INA sensor(INA 226) cannot be used for power measurement. When device with INA226 sensor is used, the Power will not be plotted in visualizer. | Motion and Presence detection OOB demo | 5.01.00.03 | xWRL6432 | None |
| SensorStop not supported in low Power configuration. | Motion and Presence detection OOB demo | 5.01.00.03 | xWRL6432 | None. |
| Using 32KB RAM memory (Range: 0x00458000 to 0x0045ffff) in application can cause issues. This block is being used by RBL. | General | 5.01.00.03 | xWRL6432 | Use this block of memory for sections like Stack, Heap, BSS (if allocated contiguously). |
| RangeProc and DOAProc examples are in development | Datapath Examples | 5.01.00.03 | xWRL6432 | None. |
Upgrade and Compatibility Information
- Attention
- When migrating from Processor/Older SDK RTOS, see Migration Guides for more details
This section lists changes which could affect user applications developed using older SDK versions. Read this carefully to see if you need to do any changes in your existing application when migrating to this SDK version relative to previous SDK version. Also refer to older SDK version release notes to see changes in earlier SDKs.
Compiler Options
| Module | Affected API | Change | Additional Remarks |
| Release Build | - | The release build with ti-arm-clang compiler has been done with Os optimization level. It is recommended that user rebuilds the existing libraries and applications with 'Os' option. This can be done by updating CFLAGS_release in library/example makefiles. |
