Test Environment

Operating System Information

Hardware Information

  • ESP32-C2（ESP8684）

Installation Steps

Install ESP-IDF

The environment installation for ESP32-IDF can mainly refer to the official website link: https://docs.espressif.com/projects/esp-idf/en/v5.4/esp32c3/get-started/index.html#get-started-how-to-get-esp-idf Both graphical interface and command line development have good results.

Prepare Project Repository

git clone https://github.com/espressif/esp-idf

Compile Code

cd esp-idf/examples/system/freertos/real_time_stats
idf.py menuconfig
idf.py build

Adjust parameters in menuconfig according to the board used.

Flash Image

After confirming the connection to esp32c2, flash the image. In a Linux development environment, you may need to add and apply udev rules in advance (the GROUP may need to be changed depending on the distribution).

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port you want to use.)

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

For the complete steps to configure and use ESP-IDF to build projects, refer to the Getting Started Guide.

Observe Log

Connect the development board via serial port.

Expected Result

The system starts normally, and information can be viewed through the onboard serial port .

Actual Result

The system starts normally, and information can be viewed through the onboard serial port .
