Start Application Development

Before powering up your M5Stack Fire, please make sure that the board is in good condition with no obvious signs of damage.

System requirements

Prerequisites

Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command below to retrieve those files.

west blobs fetch hal_espressif

Note

It is recommended running the command above after west update.

Building & Flashing

The m5stack_fire board supports the runners and associated west commands listed below.

	flash	debug	rtt	debugserver	attach
esp32	✅ (default)
openocd	✅	✅ (default)	✅	✅	✅

Build and flash applications as usual (see Building an Application and Run an Application for more details).

# From the root of the zephyr repository
west build -b m5stack_fire/esp32/procpu samples/hello_world

The usual flash target will work with the m5stack_fire board configuration. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b m5stack_fire/esp32/procpu samples/hello_world
west flash

The baud rate of 921600bps is set by default. If experiencing issues when flashing, try using different values by using --esp-baud-rate <BAUD> option during west flash (e.g. west flash --esp-baud-rate 115200).

You can also open the serial monitor using the following command:

west espressif monitor

After the board has automatically reset and booted, you should see the following message in the monitor:

***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx *****
Hello World! m5stack_fire

Debugging

M5Stack Fire debugging is not supported due to pinout limitations.
