Error message- Failed to identify the firmware ID code_E8a

Last Updated:10/11/2017


When I start up the E8a emulator to use with an R32C series MCU, the following error message appears and the E8a does not run. How can I resolve this problem?
Error message: Failed to identify the firmware ID code.


When the E8a is started up, the debugger writes the firmware to the MCU’s built-in flash memory. This error message is generated if the firmware was not successfully written to the memory.

The firmware write may fail if the power supply voltage applied to the MCU exceeds the range allowed when writing to the flash memory.

Make sure the power supply voltage to the MCU is within the range specified in the MCU’s electrical characteristics.
