ESP32-S2/S3 Upload Failure: Needs --after no_reset Option

[DocKenny]

Describe the problem

When uploading code to the ESP32-S2 or ESP32-S3 boards using the Arduino IDE, the process fails with a warning that the board cannot exit download mode over USB. This issue persists due to the lack of the --after no_reset option in the esptool command used by the IDE.

To reproduce

1. Connect an ESP32-S2 or ESP32-S3 board to your computer via USB.
2. Open the Arduino IDE and select the appropriate board under Tools > Board.
3. Load any sample sketch and attempt to upload it to the board.
4. Observe the error in the console output indicating that the board cannot exit download mode.

Expected behavior

The sketch should upload successfully without errors.

Arduino IDE version

2.3.3

Operating system

Windows

Operating system version

Windows 10

Additional context

This issue seems to be specific to boards like the ESP32-S2/S3 that use GPIO0 for download mode. A manual workaround is to add --after no_reset to the esptool command, but this requires user intervention and is not conducive to a smooth workflow. For more context and related discussions, please refer to this pull request on the esptool repository: esptool PR #997.

Hi @DocKenny. This issue is specific to the ESP32 and other boards platforms that use esptool. The esptool command is configured in the platform.

So there is nothing that can or should be changed in the Arduino IDE codebase hosted in this repository. Instead, it should be done in the boards platform.

You should report it to the "esp32" boards platform developers here:
