Operating System Information

Hardware Information

  • ESP32-C6-DevKitC-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 esp32c6_devkitc samples/basic/sys_heap

Flash Image

After confirming the connection to ESP32-C6, 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
