Esptool install for Alvik

Official Hardware Education Alvik

Hi,

I have Python and esptool installed on my Mac, but I don't see esptool in the programmer tab. Is there a certain directory esptool needs to be installed in? Thank you.

Hi @mfusco. esptool is installed along with the "Arduino ESP32 Boards" platform. Have you already installed that platform via the Arduino IDE Boards Manager? If so, select Tools > Board > Arduino ESP32 Boards > Arduino Nano ESP32 from the Arduino IDE menus. After doing that, you will find an esptool option under Arduino IDE's Tools > Programmer menu.

Thank you for your help. I'm now getting this error:

Just as you use libraries in your sketch code, libraries may use other libraries. When you are using one of the libraries that does this, it is necessary to install the other libraries on which the library depends in addition to the library you are using directly in your sketch.

The "Arduino_Alvik" library has a dependency on the "ucPack" library. You don't have the "ucPack" library installed, so the compilation fails with this "No such file or directory" error. It is odd that you don't have this library because the Arduino IDE Library Manager offers to install it for you when you install the Arduino_Alvik library. I guess you declined the offer. In the future, you should make sure to accept the offer to install library dependencies, unless you have a specific reason for not wanting them to be installed.

You can solve it by installing the missing library.

I'll provide instructions you can follow to do that:

  1. Select Sketch > Include Library > Manage Libraries... from the Arduino IDE menus to open the "Library Manager" view in the left side panel.
  2. Type ucPack in the "Filter your search..." field.
  3. Find the "ucPack" entry in the list of search results.
  4. You will see an "INSTALL" button at the bottom of the entry. Click the button.
  5. Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

    ⓘ Successfully installed library ...

Now try compiling or uploading the sketch again. Hopefully this time it will be successful.

Thank you, that worked! I'm not sure why I didn't have it installed already.

I'm now getting an error:

A fatal error occurred: Failed to connect to ESP32-S3: No serial data received.

I followed all the steps, perhaps I'm not resetting the board at the right time?

Hi, just following up.

The issue prior was that I wasn't pressing the reset button as the console printed "Connecting....". I am now getting this error:

A serial exception error occurred: Could not configure port: (6, 'Device not configured')
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

Failed programming: uploading error: exit status 1

Additionally now for some reason the Alvik ESP32 isn't being recognized by the IDE.

Edit: The IDE is recognizing the board now, but I'm still unable to upload any sketches.
