Problem: I just flashed WLED onto a newer ESP32 development board to drive my HUB75 LED panels, but I have run into a serious issue where the firmware simply will not boot. Although the flashing tool reported success and the hardware works fine in other projects, I am not seeing the WLED setup AP and the device remains completely unresponsive. Given the specialized hardware requirements for HUB75 and the recent evolution of official WLED support, what is the fundamental reason why the firmware can be flashed successfully but fails to execute on this specific setup?
Answer: Mainline WLED lacks HUB75 drivers for this hardware and requires a specialized fork like MoonModules to function.
