Release Notes 09.02.00

Table of Contents

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 explicitly noted otherwise, the SW modules would work in both FreeRTOS and no-RTOS environment.
Unless explicitly noted otherwise, the SW modules would work on any of the R5F's present on the SOC.
Attention
Current PMIC support in SDK is bare minimum meant to power up the modules and should not be used beyond this including safety use-case etc
Note
CSP 12.7 or beyond needs to be used for XIP load/run from CCS. Refer Update CSP for installation steps.

xbar SOC_xbarSelectInputXBarInputSource, SOC_xbarSelectPWMXBarInputSource, SOC_xbarSelectInterruptXBarInputSource, SOC_xbarSelectDMAXBarInputSource, SOC_xbarSelectPWMSyncOutXBarInput added SOC_xbarSelectInputXBarInputSource_ext, SOC_xbarSelectPWMXBarInputSource_ext, SOC_xbarSelectInterruptXBarInputSource_ext, SOC_xbarSelectDMAXBarInputSource_ext, SOC_xbarSelectPWMSyncOutXBarInput_ext both API versions are kept for compatibility purposes. for the additional/ extended configurations on xbar "API", please use "API_ext" GPIO NA The GPIO deviceData has been modified to reduce the load from the solver working at the backend of sysconfig application. Instead of choosing the gpio peripheral GPIO0 or GPIO1 for the main domain, user can now directy choose the pins. With this change, user can add as many gpios as possible without facing any sysconfig crash. SDK changes thereby had to be adjusted accordingly. Please note that these changes are backward compatible, so the old example.syscfg will still work. However, this change will break compatibility with users who are not using the SDK but directly using pinmux. They will have to remove the gpio related configurations from their syscfg file, then open the file in syscfg and add those gpios configurations again via gui.
