Flexible Software Package (FSP) for Renesas RA MCU Family
FSP is the next generation Arm® MCU software package from Renesas, that enables secure devices and IoT connectivity through production ready peripheral drivers, Azure RTOS or FreeRTOS, and portable middleware stacks. FSP includes best-in-class HAL drivers with high performance and low memory footprint. Middleware stacks with Azure RTOS and FreeRTOS integration are included to ease implementation of complex modules like communication and security. The e² studio ISDE provides support with intuitive configurators and intelligent code generation to make programming and debugging easier and faster.
FSP uses an open software ecosystem and provides flexibility in using your preferred RTOS, legacy code, and third-party ecosystem solutions.
For a list of software modules packaged with FSP, see Supported Software.
On November 21, 2023, Microsoft announced that they have decided to contribute Azure RTOS to open source under the stewardship of the Eclipse foundation and Azure RTOS will become Eclipse ThreadX. For detailed information, please refer to the announcement at Microsoft Contributes Azure RTOS to Open Source.
The support strategy scheme for Eclipse ThreadX will be determined and communicated at a later date. Microsoft will discontinue the Azure RTOS and Azure RTOS Middleware under the existing agreement LICENSED-HARDWARE.txt.
It is important to note that updates for Azure RTOS on these hardware will no longer be provided.
Product Security Advisories for FSP and third party software (where available) are tagged with the 'product_security_advisory' label. Please check these issues for information from the respective vendors for affected versions and a recommended workaround or patch upgrade.
Visit GitHub Issues for this project.
Critical issues that cause an MCU to operate out of the hardware manual documented specifications are tagged with the 'critical' label. Please check critical issues before going to production for a workaround or recommended patch upgrade.
If you have already installed a previous FSP release that included e² studio then you can download the packs separately. These are available for download under the Assets section for each release. There is a zipped version, FSPPacks\<version>.zip, that will work on any supported OS. There is also a self-extracting installer version, FSPPacks\<version>.exe, that will work on Windows.
When using the zipped version of the packs the zip file should be extracted into the e² studio support area. This directory is typically found under the user's home directory with a path such as ~/.eclipse/com.renesas.platform_2047834950. The number on the end of the path is unique to each e² studio installation. If you have two e² studio installations then you will have two directories with names of the format ~/.eclipse/com.renesas.platform_<unique_number>. Please note that e² studio must have been run at least once for this directory to be created. You can find the support area for a particular e² studio installation by clicking Help >> About e² studio. In the window that pops up click Installation Details and choose the Support Folders tab. The e² studio support area path will be shown.
