Flexible Software Package (FSP) for Renesas RZ.

FSP is the next generation Arm® MPU software package from Renesas, that enables HMI 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 IDE 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.

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.

Refer to the release notes for each version.

• FSP versions of 4.0.0 and later requires a minimum e² studio version of 2025-12.
• FSP versions of 4.1.0 and later requires a minimum e² studio version of 2026-04.1.
• FSP versions of 4.2.0 and later requires a minimum e² studio version of 2026-07.

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, FSP_Packs_<version>.zip, and an installer version, FSP_Packs_<version>.exe.

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 e<sup>2</sup> 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.
