Supported MCUs (RX FreeRTOS)

The microcontrollers supported by RX FreeRTOS and their corresponding portable layer folders are summarized in the table below. You can determine the appropriate portable layer based on the combination of the microcontroller and compiler combination.
In the “RX MCU Group” column, 🔵 indicates microcontrollers that support the PG function, while 🔴 indicates microcontrollers that do not support the PG function. The microcontrollers that do not support the PG function are not covered by technical support through Renesas Technical Support “Support Tickets”.

Limitation (RX FreeRTOS)

• Do not switch the stack to the USP during interrupt processing.
• Always operate in supervisor mode with respect to the processor mode.
