Operating System Information

Hardware Information

  • ESP8684-DevKitM-1

Installation Steps

Install Zephyr

Configure the Zephyr environment according to the Zephyr documentation:
https://docs.zephyrproject.org/latest/develop/getting_started/index.html

Prepare Project Repository

cd zephyr

Compile Code

west build -p always -b esp8684_devkitm samples/basic/sys_heap

Flash Image

After confirming the connection to ESP32-C2, 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).

west flash
west espressif monitor

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

Observe Log
