Using IDE 2.0.4 I had a similar problem when I upgraded the ESP32 board files to version 2.0.7 from 2.0.6

I have not investigated the problem, but reverting to the ESP32 board files version 2.0.6 solved the problem

Interestingly, I just upgraded to board files 2.0.7 again and the problem is no longer occurring, so I don't know what is going on

Thanks. It's working.

UKHeliBob · March 5, 2023, 10:43am

What did you do ?

ptillisch · March 5, 2023, 6:02pm

I did some investigation and found this error was caused by a change made to the ESP32 package index file:

github.com/espressif/arduino-esp32

Path to esptool not discoverable due to post-release tool dependency bump

### Board All ### Device Description N/A ### Hardware Configuration … N/A ### Version v2.0.7 ### IDE Name Arduino IDE 1.8.19, 2.0.4, Arduino CLI 0.31.0 ### Operating System All ### Flash frequency N/A ### PSRAM enabled yes ### Upload speed N/A ### Description The [package index](https://arduino.github.io/arduino-cli/latest/package_index_json-specification/) provides support for installation of the platform via the Arduino Boards Manager. In addition to the platform itself, Boards Manager also installs the tool dependencies that are defined in the release entry. The package index data is also used by the Arduino development tools to expand [the `runtime.tools.TOOLNAME.path` properties](https://arduino.github.io/arduino-cli/latest/platform-specification/#how-to-retrieve-tools-path-via-runtimetools-properties) used in the command patterns defined in `platform.txt` to the paths of the tool dependencies installed on the user's computer. The [`packages[*].platforms[*].toolsDependencies[*].version`](https://arduino.github.io/arduino-cli/0.31/package_index_json-specification/#platforms-definitions:~:text=core%20archive%20file)-,toolsDependencies,-%3A%20the%20tools%20needed) field for the `esp32:esptool_py` tool dependency of the 2.0.7 platform release was changed from `4.5` to `4.5.1`: https://github.com/espressif/arduino-esp32/commit/50269f6ec02bb341d878ff57d7ea5fc8c9ac82fe This causes compilation or upload to fail under the following conditions: - The user installed version 2.0.7 of the platform before [the change](https://github.com/espressif/arduino-esp32/commit/50269f6ec02bb341d878ff57d7ea5fc8c9ac82fe) was made to the package index. - The [ESP32 package index URL](https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json) is in their "**Additional Boards Manager URLs**" IDE preference. - The package index file has been updated on the user's computer (the Arduino development tools do this automatically). #### Suggested Fix Make a new release of the platform. #### Workaround The user can use Boards Manager to uninstall and then reinstall the platform: ##### Arduino IDE 1.x 1. Select **Tools > Board > Boards Manager** from the Arduino IDE menus. A "**Boards Manager**" dialog will appear. 1.

Wait for the installation to finish. #### Additional reports - https://github.com/arduino/Arduino/issues/11866 - https://forum.arduino.cc/t/t-display-s3-esp32s3-how-to-reset-to-factory-settings-after-burn-bootloader/1096636 - https://forum.arduino.cc/t/esptool-exe-is-not-recognized-as-an-internal-or-external-command-an-executable-program-or-batch-file/1096495 - https://forum.arduino.cc/t/esp32-s3-stuck-with-manual-uploading-resetting/1096945/3 - https://forum.arduino.cc/t/compilation-error-esptool-exe-not-recognized/1096550 - https://forum.arduino.cc/t/problem-latest-update-ide/1095897/5 ### Sketch ```cpp void setup() {} void loop() {} ``` ### Debug Message **Arduino IDE 2.x** / **Arduino CLI**: ```text cmd /c IF EXIST "C:\\Users\\per\\Documents\\Arduino\\sketch_mar2a\\bootloader.bin" ( COPY /y "C:\\Users\\per\\Documents\\Arduino\\sketch_mar2a\\bootloader.bin" "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-D4D9383D25724F4612E543EFB0213587\\sketch_mar2a.ino.bootloader.bin" ) ELSE ( IF EXIST "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\2.0.7\\variants\\esp32\\bootloader.bin" ( COPY "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\2.0.7\\variants\\esp32\\bootloader.bin" "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-D4D9383D25724F4612E543EFB0213587\\sketch_mar2a.ino.bootloader.bin" ) ELSE ( /esptool.exe --chip esp32 elf2image --flash_mode dio --flash_freq 80m --flash_size 4MB -o "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-D4D9383D25724F4612E543EFB0213587\\sketch_mar2a.ino.bootloader.bin" "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\2.0.7\\tools\\sdk\\esp32\\bin\\bootloader_qio_80m.elf" ) ) '/esptool.exe' is not recognized as an internal or external command, operable program or batch file. 1 file(s) copied. ``` **Arduino IDE 1.x**: ```text ___REMOVE___/esptool.exe --chip esp32 --port COM10 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size 4MB 0x1000 C:\Users\per\AppData\Local\Temp\arduino_build_839818/foo_bar.ino.bootloader.bin 0x8000 C:\Users\per\AppData\Local\Temp\arduino_build_839818/foo_bar.ino.partitions.bin 0xe000 C:\Users\per\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.7/tools/partitions/boot_app0.bin 0x10000 C:\Users\per\AppData\Local\Temp\arduino_build_839818/foo_bar.ino.bin java.io.IOException: Cannot run program "___REMOVE___/esptool.exe": CreateProcess error=2, The system cannot find the file specified ``` ### Other Steps to Reproduce 1. Use Boards Manager to install version 2.0.7 of the platform if it is not already installed: https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#installing-using-arduino-ide 1. If you have installed the platform after the time of the package index change, adequately simulate the conditions by exiting Arduino IDE and renaming the folder at the following path to `4.5`: - **Windows**: ```text C:\Users\<username>\AppData\Local\Arduino15\packages\esp32\tools\esptool_py\4.5.1 ``` (where `<username>` is your Windows username) - **Linux**: ```text ~/.arduino15/packages/esp32/tools/esptool_py/4.5.1 ``` - **macOS**: ```text ~/Library/Arduino15/packages/esp32/tools/esptool_py/4.5.1 ``` 1. Trigger an update of the package index: - **Arduino IDE 1.x**: 1. Select **Tools > Board > Boards Manager** from the Arduino IDE menus. A "**Boards Manager**" dialog will appear. 1. Wait for the updates to finish, as shown by the messages printed at the bottom of the "**Boards Manager**" dialog. 1. Click the **<kbd>Close</kbd>** button on the "**Boards Manager**" dialog. - **Arduino IDE 2.x**: 1. Press the <kbd>**Ctrl**</kbd>+<kbd>**Shift**</kbd>+<kbd>**P**</kbd> keyboard shortcut (<kbd>**Command**</kbd>+<kbd>**Shift**</kbd>+<kbd>**P**</kbd> for macOS users) to open the "Command Palette". 1. Select the "**Arduino: Update Package Index**" command from the menu. 1. Wait for the "**Downloading index: ...**" notification to close. 1. Select any ESP32 board from Arduino IDE's **Tools > Board** menu. 1. Select a serial port from Arduino IDE's **Tools > Port** menu. 1. Select **Sketch > Upload** from the Arduino IDE menus. 🐛 The process fails due to an incomplete path to `esptool` in the compilation or upload command. ### I have checked existing issues, online documentation and the Troubleshooting Guide - [X] I confirm I have checked existing issues, online documentation and Troubleshooting guide.

You can restore the platform to a functional state by uninstalling and then reinstalling it:

Select Tools > Board > Boards Manager from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
Scroll down through the list of boards platforms until you find the "esp32 by Espressif Systems" entry.
Hover the mouse pointer over the "INSTALLED" label on the "esp32 by Espressif Systems" entry. You will now see it change to an "UNINSTALL" button.
Click the "UNINSTALL" button.
A confirmation dialog will appear. Click the "YES" button.
Wait for the uninstallation to finish.
Select "2.0.7" from the dropdown version menu at the bottom of the "esp32 by Espressif Systems" entry.
Click the "INSTALL" button at the bottom of the "esp32 by Espressif Systems" entry.
Wait for the installation to finish.
