ELF Loader Example

This example shows how to use ELF loader to run ELF file.

How to Use Example

Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>.

• Note: Only ESP32, ESP32-S2 and ESP32-S3 are supported

Hardware Required

• A development board based on espressif ESP32/ESP32-S2/ESP32-S3 SoC
• A USB cable for power supply and programming

Configure the Project

Open the project configuration menu (idf.py menuconfig).

In the Example Configuration menu:

• Enable ELF input arguments in the Support arguments for ELF main option if necessary.
• Set the arguments in the Arguments of ELF main option.

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)
