After you have changed the target microcontroller for a project in the CubeSuite+ environment, change the following setting.
In [Property] of the CC-RX (build tool), change the setting for [Section] -> [Section start address] on the [Link Options] tabbed page to suit the ROM or RAM space of the CPU you will be using.
In CS+ 3.00.00 and later versions, the section start addresses allocated by default correspond to the ROM and RAM sizes for the RX MCU that you have selected for the project.
