Using Arduino IDE 2.3.4 to verify a sketch and received this Compilation error: Exit Status 255.
What I'm trying to do is use an existing sketch created by someone else (as explained in the attached sketch) and then upload it to my ESP32 Servo Driver Expansion board w/built in WiFi & Bluetooth. Then I can use the ESP32 Kit App on my iPhone to operate the ESP32 Servo driver Expansion board wirelessly.

While verifying my sketch using Arduino IDE 2.3.4, I received a Compilation error: Exist status 255. Can someone help to resolve this error ?

Release Notes:
- V1.1 Created 29 Dec 2019
Installation instructions using Arduino IDE Boards Manager:
1- Go to this link and follow the instructions:
https://github.com/espressif/arduino-esp32/blob/master/README.md
2- Go to Tools/Board/Boards Manager
3- Search for: ESP32
4- Install the Package: esp32 by Espress Systems version 1.0.4
5- Go to Tools/Board then select ESP32 Dev Module
6- Go to Tools/Partition Scheme then select Huge App(3MB No OTA / 1MB SPIFFS)
7- Update the below WIFI creditntial to your WIFI ssid and password.
8- That's it, Now you can upload the sketch to your board.
Connection:
- No connections are required, Just upload the sketch to your ESP32 board.

post the code with code tags, not as an attachment we can't read easily on our smartPhone
(please read How to get the best out of this forum and post accordingly)
Ok. I followed the code tags direction and loaded the code
Thx - is that all the compiler is saying?
Yes.
Can you compile an empty sketch for your target platform ?
Let me try quickly
The empty sketch doesn’t work either. Still getting the, Compilation error: Exit status 255
The Compilation error: Exit status 255 typically indicates a failure in the build process - so some missing files or IDE not installed correctly, missing included files or loops in the included etc
Did you install the ESP32 board package and selected the right board for compilation?
Yes.
Installed Package: esp32 by Espress Systems version 1.0.4
Selected Board: ESP32 Dev Module
Selected, Partition Scheme: Huge App(3MB No OTA / 1MB SPIFFS)
I was getting a Python error earlier today. Then I installed Python 2 and Python 3 and that went away, and now I'm only getting the "Exit Status 255 error"
Which platform are you using?
This sounds like an IDE install issue
This feels outdated
Did you set the board package to be
https://espressif.github.io/arduino-esp32/package_esp32_index.json
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html
I just installed the board package you recommended. Thanks. Now I'm questioning if I selected the right board in Arduino. Currently I have selected "ESP32 Dev Module.
Not sure how to find the right board - I pasted a link to the ESP32 Servo board I have. Can you tell me what board I should be selecting in Arduino ?
Read their wiki - it’s not your typical Arduino it seems … (I don’t know that one)
They say
Generally, we control the ST series servos by compiling and uploading the demo through the Arduino IDE. However, compiling through Arduino requires installing various dependency libraries before use. Therefore, we provide an ESP32 download tool. With this tool, users can download the demo to the driver board without needing to download other dependency libraries or the Arduino IDE software.
This is great news. Thanks, I just downloaded the software. Give me a few minutes and I'll let you know where I am in the process
I'm using a Mac. Trying to file an app to open the exe file
They might have just a windows version…
Ok. I installed cross over and the exe file opened up and I'm now I see a screen that lets me activate servos connected to the ESP32. I connected the ESP32 servo board to my computer but it's not communicating while hardwired. Not sure what to do at this point to operate the board wirelessly. Can you help ?
I don’t have that board and never heard about it before you brought that up…
It seems very specific, did you download and explored their zip SCSTServoLibrary
https://files.waveshare.com/upload/2/22/SCSTServoLibrary.zip
