Development Tools

Like other RA products, the RA2L2 supports debuggers including Renesas Electronics’ E2/E2 Lite/EZ-CUBE3, SEGGER’s J-Link, IAR’s I-jet, Arm’s ULINK, and open-source CMSIS-DAP.

Software development relies on FSP (Flexible Software Package), which not only provides HAL Driver-level drivers but also includes rich middleware such as file systems, USB protocol stacks, and network protocols. Additionally, configurations for FreeRTOS and Azure RTOS can be completed through the FSP UI interface.

FSP can be embedded into Renesas Electronics’ IDE e² studio based on the Eclipse platform. For third-party IDEs like Keil MDK and IAR Embedded Workbench for Arm, it needs to be used with the RASC (RA Smart Configurator) standalone plugin, which can be downloaded fromGitHub (Releases · renesas/fsp), and more details can be found in the RASC documentation(RASC MDK IAR User Guide).(You can copy the link below into your browser or scan the QR code to view)
