ESP32-S3-EYE v2.2 - device not recognized by Ubuntu

[davidjaqua]

I have been programming various ESP32 Cam modules successfully using using IDF 4.4 on Ubuntu 20.04.

I recently bought an ESP32-S3-EYE v2.2.

The instructions state:
---
ESP32-S3-EYE does not have a USB-to-UART bridge, which may cause a problem: If the program flashed onto the board keeps the chip rebooting, you cannot flash more programs onto the board.

In case this issue occurs, you need to:

Hold down BOOT button and press RST button, then release RST button first, and BOOT button next. In this way, the board enters Firmware Download mode and you can start flashing program onto the board.
After flashing the program, press RST button to start the program.
---

When I press BOOT, then RST, release RST then BOOT, the default program stops.

However, the device is not recognized by the OS. ls /dev/*USB* is empty with no other USB devices plugged in.

If I plug in another device, such as an ESP-EYE or ESP32-CAM using the same cord, it appears as ttyUSB0 in /dev as expected.

I tried it under Windows, and the ESP32-S3 does appear as a COM device in device manager.

Any ideas?

Code: Select all

/dev/ttyACMx

Is the problem still present or did you solve it?

I face the same issue and it is not listed as "/dev/ttyACM*" either.

Same thing for MacOS.. doesn't show up or enumerate as a SLAB or ttyACM. Does show up as /dev/cu.usbmodem144****

Any help here?
