Renesas RA

Registry:: https://registry.platformio.org/platforms/platformio/renesas-ra
Configuration:: platform = platformio/renesas-ra

Renesas Advanced (RA) 32-bit microcontrollers with the Arm Cortex-M33, -M23 and -M4 processor cores deliver key advantages compared to competitive Arm Cortex-M MCUs by providing stronger embedded security, superior CoreMark performance and ultra-low power operation.

For more detailed information please visit vendor site.

Examples 

Examples are listed from Renesas RA development platform repository:

Debugging 

Debugging - “1-click” solution for debugging with a zero configuration.
