- Please read [the support policy](SUPPORT_POLICY.md) and [the documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) for more information about ESP-IDF versions.
- Please see the [End-of-Life Advisories](https://www.espressif.com/en/support/documents/advisories?keys=&field_type_of_advisory_tid%5B%5D=817) for information about ESP-IDF releases with discontinued support.
The following table shows ESP-IDF support of Espressif SoCs where ![alt text][preview] and ![alt text][supported] denote preview status and support, respectively. The preview support is usually limited in time and intended for beta versions of chips. Please use an ESP-IDF release where the desired SoC is already supported.
There are variants of revisions for a series of chips. See [Compatibility Between ESP-IDF Releases and Revisions of Espressif SoCs](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY.md) for the details of the compatibility between ESP-IDF and chip revisions.
**Note:** Each SoC series and each ESP-IDF release has its own documentation. Please see Section [Versions](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) on how to find documentation and how to checkout specific release of ESP-IDF.
ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub. If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.
The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete. If cloning ESP-IDF from GitHub, this step is not needed.
As well as the [esp-idf-template](https://github.com/espressif/esp-idf-template) project mentioned in Getting Started, ESP-IDF comes with some example projects in the [examples](examples) directory.
To start your own project based on an example, copy the example project directory outside of the ESP-IDF directory.
# Quick Reference
See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects:
* Install host build dependencies mentioned in the Getting Started guide.
* Run the install script to set up the build environment. The options include `install.bat` or `install.ps1` for Windows, and `install.sh` or `install.fish` for Unix shells.
* Run the export script on Windows (`export.bat`) or source it on Unix (`source export.sh`) in every shell environment before using ESP-IDF.
*`idf.py set-target <chip_name>` sets the target of the project to `<chip_name>`. Run `idf.py set-target` without any arguments to see a list of supported targets.
*`idf.py menuconfig` opens a text-based configuration menu where you can configure the project.
Replace PORT with the name of your serial port (like `COM3` on Windows, `/dev/ttyUSB0` on Linux, or `/dev/cu.usbserial-X` on MacOS. If the `-p` option is left out, `idf.py flash` will try to flash the first available serial port.
This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with `idf.py menuconfig`.
The `idf.py monitor` target uses the [esp-idf-monitor tool](https://github.com/espressif/esp-idf-monitor) to display serial output from Espressif SoCs. esp-idf-monitor also has a range of features to decode crash output and interact with the device. [Check the documentation page for details](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
The `idf.py flash` target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run `idf.py erase-flash`.
This can be combined with other targets, ie `idf.py -p PORT erase-flash flash` will erase everything and then re-flash the new app, bootloader and partition table.
