| | Step | Typical User Actions | Common Pitfalls | | :--- | :--- | :--- | :--- | | 🔌 Setup | 1. Hardware Connection | Connect a PC to the device using a null modem RS-232 cable. Laptops often require a USB-to-RS232 adapter. | Using a standard serial cable instead of a null modem; incorrect or unstable wiring of a DIY adapter. | | 2. Tool Prep | Launch the Sunplus Loader Tool and load the correct firmware ( Select ROM File ). | Selecting a firmware file that is incompatible with the target device. | | 3. Port Config | Identify the correct COM port (e.g., via Device Manager in Windows) and select the matching DDR Type (DDR2 for 4MB software, DDR3 for 8MB). | Mismatched COM port or incorrect DDR type selection. | | 4. Device Prep | Turn the device OFF (unplugged). | Attempting the process with the device already powered on. | | 🚀 Flashing | 5. Start Procedure | Click the Start button in the software. The software will often display a prompt like Turn ON the Power or Please Turn On The Power . | Failing to follow the specific timing of the power-on sequence. | | 6.
