Open Windows Device Manager. Identify the designated COM port number assigned to your serial connection.

The is the secondary bootloader responsible for initializing the Sunplus SoC (System on Chip) hardware, performing minimal memory configuration, and loading the main operating system kernel (typically Linux) into RAM. It acts as the bridge between the proprietary Sunplus BootROM (masked ROM) and the user-space operating system.

Most Sunplus loaders are lightweight executable (.exe) files built for Windows XP, 7, 10, or 11. sunplus loader
