Adafruit ESP32-S2 Feather with BME280 NOT Recognized Moderators: adafruit_support_bill, adafruit

Hello,

I just got the Adafruit ESP32-S2 Feather with BME280 Sensor.

For some reason, when it's plugged into my computer (windows 10), no drive is mounted.

Curiously, my PC detects something was connected, and the ESP32 led flashes, but nothing happen.

Under Devices and Printers, Windows shows it as Feather ESP32S2, but the rest is blank (see screenshots)

Thanks for your help,

This sounds about right if this ships without CircuitPython installed.

Have you tried uploading code via Arduino?

If you wish to use CircuitPython you would need to enter bootloader mode to see the BOOTPY or equiv drive.

Try pressing the holding the BOOT button down and press reset (then release BOOT).

Thanks for the suggestion. Unfortunately when I do "Try pressing the holding the BOOT button down and press reset (then release BOOT)" , the board LEDs turn off and no new drive is mounted, I am starting thinking this was DOA.

Now windows reports for the "ESP32-S2 device"

"The drivers for this device are not installed. (Code 28)

There are no compatible drivers for this device.


To find a driver for this device, click Update Driver."

Win10 includes the necessary USB serial drivers and you have a COM port and USB ID. The board is hardware sound, but it looks like you need to install the UF2 bootloader.

https://github.com/adafruit/tinyuf2/rel ... -0.5.2.zip

Install, Repair, or Update UF2 Bootloader
Latest version: 0.5.2

The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. If a UF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.)

It is not necessary to reinstall a UF2 bootloader you unless a BOOT drive is not visible when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader.

If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash .uf2 files onto the board. .bin files can be uploaded without a UF2 bootloader, using the Adafruit WebSerial ESPTool or esptool.py.

Note: update.uf2 files are not currently working on ESP32-S2 boards.

Important: this will erase previously flashed firmware and sketches from the board, but needs to be perfomed only once.

Unzip to find the file combined.bin.
Place board in bootloader mode:
Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
Press and hold down the BOOT or 0 button.
Press and release the RESET or RST button.
Release the BOOT button.
Upload combined.bin (Google Chrome 89 or newer):
Open Adafruit WebSerial ESPTool in a new window/tab.
Select 460800 Baud from the pull-down menu (top-right).
Click Connect (top-right).
Select the COM or Serial port from the pop-up window.
After successful connection, click Erase.
After successful erase, click any Choose a file..., then locate and select the combined.bin file unzipped earlier.
After successfully choosing combined.bin, click Program.
After the TinyUF2 firmware update is complete, press the RESET button on the board. A new drive BOOT should be visible in your file browser.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to load or reload CircuitPython using the .uf2 file.

Thank you for your help.
Following your steps to load the UF2 bootloader fixed the issue.

Thanks again for your support.

Excellent. Thank you for the followup. Happy hacking.
