Flashing Tool

Use the tool below to flash firmware to your MAKCU device.

Important: COM Port Limitation

This tool is only for flashing and testing MAKCU. MAKCU only allows one device to be connected to USB 2 (COM port) at a time. Please ensure this AIO tool is closed before using MAKCU with your software, otherwise your software will not be able to connect.

First Time Flashing

If your MAKCU comes without firmware or has not been tested, it is normal to be connected to USB 1 or 3 without holding buttons down and the USB sound to loop endlessly. This is the ESP32-S3 chip's default state from the factory. Upon the first flash, this state will go away and never return.

USB 1 - Left Side

USB 1 corresponds to the left side - select firmware with 'LEFT' in the name

USB 3 - Right Side

Note: Check the numbers printed on the MAKCU board to ensure you match the correct USB port to the correct side
