Everything is all right but program does not start

Hi All,
I am new to PlatformIO, I have installed everything and started a small program.
Compilation and upload is successful.

I see the message “Hard resetting via RTS pin…” but the program does not starts on ESP 32.
I played with platformio.ini, look at some similar issues on Internet but no way it simply does not work.

From the Arduino IDE, everything is working fine.

Here is my ini :

platform = espressif32
board = az-delivery-devkit-v4
framework = arduino
lib_deps =
monitor_speed = 115200

Do you know what could be wrong ?


Have you tried building and uploading a simple blink sketch to make sure all is well?

Full platformio.ini details for your AZ Delivery board (A great company to deal with by the way!) can be found at AZ-Delivery ESP-32 Dev Kit C V4 — PlatformIO latest documentation, in case it helps.

You don’t appear to have any upload parameters in your ini file.


Most likely error is that you’ve not selected the right active project.

Ok, thank you for your messages.
I just tested the blink example and here it works.
So should be an issue in my code.
Have to investigate.
