<![CDATA[UIFlow Desktop: “Upload code failed, device offline” error with M5Stack Core2 (Windows 10)]]>I would like to program my M5Stack Core2 ESP32 using the UIFlow Desktop Version on Windows 10.

2026-03-05_08-52-57.png

My progress so far:

1.) Installed the CP2104 USB-to-UART Bridge Controller driver on my computer.

2.) Connected the M5Stack Core2 ESP32 to my computer via USB.

3.) Flashed UIFlow 2.0 Firmware (v2.4.2-Core2) using the M5Burner tool.

4.) Started UIFlow-Desktop-IDE.exe.

5.) When trying to upload code, I get the following error:

ERROR: Upload code failed, maybe your device is offline check it and retry.

Could someone help me understand what I might be doing wrong or what I should check next?
