Source codes in the porting layer is divided into multiple folders, and each folder contains codes for a specific device. Users need to choose the appropriate folder based on the characteristics of each device.
Judging from the folder names, it appears that the applied folder is determined by conditions of the MCU series and CPU core. However, the applied actual conditions don't always match this.

The folder that should be chosen for each RX family device is shown in the table below. The Renesas support window "Submit a Ticket" (see Renesas Support) only supports devices in the "Supported device" column in this table.

Folder name	Applied actual conditions	Supported device (Note 1)	Non-supported device (Note 2)
RX100	RX100 Series + RXv1 core	RX130	RX110 RX111 RX113 RX13T
RX200	RX200 Series + RXv1 core	-	RX210 RX21A RX220
RX600	RX600 Series + RXv1 core	-	RX610 (Not Recommended) RX621 RX62G RX62N RX62T RX630 RX631 RX634 RX63N RX63T
RX600v2	RXv2 core + without DPFPU or RXv3 core + without DPFPU (Note 3)	RX140 RX230 RX231 RX23E-A RX23E-B RX23W RX24T RX260 RX261 RX26T RX64M RX651 RX65N RX660 RX66T RX71M RX72T	RX23T RX24U RX65W-A
RX700v3_DPFPU	RXv3 core + with DPFPU (Note 3)	RX66N RX671 RX72M RX72N	-

• Note 1: Supported for PG feature.
• Note 2: Non-supported for PG feature. (Although it is theoretically possible to run FreeRTOS with creating a project manually by the user, Renesas support window "Submit a Ticket" doesn't support that.)
• Note 3: MCU series are not involved in the condition.

• When you use a GCC compiler, don't enable to the DPFPU because the context save/restore for DPFPU-related registers is not supported.
