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

Known Issues

ID	Head Line	Module	Applicable Releases	Applicable Devices	Workaround
MMWLPSDK-244	HWA decompression output minor deviations	HWA driver	5.01.00.03	xWRL6432	None
MMWLPSDK-243	Limited configuration support.	Motion and Presence detection OOB demo	5.01.00.03	xWRL6432	None
MMWLPSDK-229	In low Power mode when the configuration is such that there is no enough time to entry-exit deep sleep, demo is halted.	Motion and Presence detection OOB demo	5.01.00.03	xWRL6432	Change the configuration providing sufficient time for deep sleep entry-exist (i.e. increase frame periodicity)

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.
