EasyLoader is a quick and user-friendly program burning tool. Each product page includes EasyLoader, which provides a related case program that can be easily flashed to the main controller, enabling functional verification. After downloading, double-click to run the application, connect your M5 device to your computer via USB, set the port parameters, then click "Burn" to start the process. (For M5StickC, please set the baud rate to 750,000 or 115200 during the burning process.) EasyLoader is currently only available for the Windows operating system and is compatible with the M5 system, which uses the ESP32 core. You must install the CP210X driver before burning for M5Core (not needed if using M5StickC as the controller).
