The following error is displayed because the setting of the emulator debugger on a workspace is not E8a but E8.
The title “E8R8C” in message window differs by device.
The emulator debugger of the E8a is different from that of the E8, so select [Debug] -> [Debug Settings] from the High-performance Embedded Workshop menu, and open the [Target] tab in the [Debug Settings] dialog box, and change the setting of [Target] to [XXX E8a SYSTEM]* .
If the E8a emulator debugger according to the MCU used in your systems is not installed, [XXX E8a SYSTEM] in the pull-down menu of [Target] is not displayed, so please download and install the E8a emulator debugger according to the MCU used in your systems.
Note: Please refer to here about switchover from E8 to E8a.
* [XXX E8a SYSTEM] is displayed depending on the MCU used in your systems.
R8C family: R8C E8a SYSTEM
