Can't flash ESP32-S2 via USB-DFU: LIBUSB_ERROR_TIMEOUT
Posted: Wed Jul 12, 2023 9:06 am
I have an ESP32-S2-SOLO module on a custom PCB, with my USB data lines connected directly to the ESP32-S2 D+ and D- pins.
I can see the ESP32-S2 in the Device Manager (and its associated COM port) when the chip is booted in download mode, and I have the drivers installed (Windows 11). I can compile the code just fine using VS Code with ESP IDF (just the blink test program for now).
When I try to flash the chip via DFU, dfu-util seems to be able to detect and communicate with the device, but the download never goes past 0%, and then I get an error:
The full output is:
dfu-util can detect the device and list it:
So I don't think it's a bad PCB or anything like that: voltages, continuity on the data lines and everything are all as you'd expect.
This is my first time using the built-in USB controller rather than a USB-UART bridge.
Has anyone faced this problem before or does anyone know how it might be solved?
