Can't connect to Feather ESP32-S2

Post by dshorstein »

When I plug in the feather to USB, it doesn't show up on either my linux or windows machine. I was able to connect to the Serial port showing a blank screen. I tried using the Adafruit Web ESPTool but got an error message when trying to connect.

I first tried connecting before putting it into bootloader mode, and it said

Code: Select all

Error: Failed to set control signals.
Next I put the board in bootloader mode (press and release Reset while holding Boot) but I got repeated messages of

Code: Select all

EspLoader.readPacket:503] Timed out waiting for packet header
Timed out after 100 milliseconds
followed by

Code: Select all

Error: Couldn't sync to ESP. Try resetting.
Is this board bricked or am I missing something here?

You might have the button pattern mixed up for entering bootloader mode. Try a factory reset.
To enter bootloader mode, plug in the board into a USB cable with data/sync capability. Press the reset button once, wait till the RGB LED turns purple, then press the reset button again. Then drag this file over:
