ESP32 ESP-IDF

Hi,

I'm using VM to write and compile code for ESP32. I have two problems.
First, is it possible to use ESP32 ESP-IDF with VM and not Arduino version? If yes, how do I start new project using ESP-IDF?

I have ESP32 board with 16MB flash. If I select bigger partition size from VM menu, say 8MB or 16MB, I do not see any changes when building image. It still displays "Program FreeRTOS size: 275093 bytes (used 21% of a 1310720 byte maximum)".

When I upload the bin, program keeps restarting. If I use default option of 4MB, everything works. How do I select bigger flash size?

Brgds,
Damjan

IDF: You can only use cores that are compatible with the Arduino framework. 

Flash: Please follow guide in yellow above

Newbie here. What do you mean when you say "core"?

A core is usually installed using Board Manager, either in the Arduino IDE or Visual Micro. Board Manaer downloads and installs packages. 

A package consists of a tool chain and core. The core defines code that you can reference such as digitalread(). The tool chain is the .exe files that are used in background to compile and upload.

Esp32 package/core by Espressif (manufacturer of esp32) does use some of IDF under the hood, but that is preset by them.

The esp32 Arduino compatible package allows tools, such as Visual Micro, to know how to power intellisense and compile code.

If you have not installed it already you will find it under the auto-discovery node at the top of the Board Manager. See our docs for how Board Manager works (if need be).
