If you need a custom firmware, for example a module only available on the development version, save space … you can read this previous article that shows how to get a custom firmware through frightanic nodemcu_build.įirmware flashing is an energy consuming operation (with peaks between 200 and 300mA). You should get a message indicating the firmware version and an error message NodeMCU 0.9.6 build 20150704 powered by Lua 5.1.4

Now open your Arduino IDE and open the Serial Monitor. The blue LED on the antenna will blink throughout the operation.
You can track the progress of the update from the terminal. If everything is correct, esptool starts by erasing the flash memory and then downloads the firmware. Small reminder how to do for those who discover Sudo python esptool.py -baud 921600 -port /dev/tty.usbserial-A1048DR2 write_flash -fm dio 0x00000 ~/Downloads/nodemcu_integer_0.9.6-dev_20150704.binĭepending on your ESP8266 module, you may need to bootload this mode. Don’t forget to modify PORT_COM and BIN_PATH before to execute the command sudo python esptool.py -baud 921600 -port COM_PORT write_flash -fm dio 0x00000 BIN_PATH.BIN In my case it is connected to /dev/tty.usbserial-A1048DR2Īll that remains is to prepare the command to flash the firmware. The command returns the list of devices connected to your Mac. To identify the serial port on which your board is located, you can use the Arduino IDE or enter the following command ls /dev/tty.* To write this article, I used the binary nodemcu_integer_0.9.6-dev_20150704.bin.Ĭonnect your ESP8266 NodeMCU board using an FTDI module (or a USB cable depending on the board you have). Download the version that corresponds to your project. Now that esptool is ready, download the latest firmware NodeMCU ESP8266 by visiting github.
#2017 esp8266 firmware install
sudo python setup.py install Update firmware ESP8266 NodeMCU with esptool.py on macOS You will need to enter your password to allow the command to run. Now we will execute the script setup.py which allows to add the necessary dependencies (in particular pySerial). We will recover esptool by cloning it from github with command. Let’s now go to the Document directory (or the directory of your choice, it is equal) like this cd ~/Documents Do not forget to leave python by entering exit (), quit () or Ctrl + D before continuing. If this is not the case install python 2.7 by visiting here. Type "help", "copyright", "credits" or "license" for more information. If everything is properly installed you should have a message like this
To find out if python is already present on your machine, simply type the python command in the Terminal.
#2017 esp8266 firmware mac os
Provide an FTDI module (or cable) if your module is equipped with a programming interface via a COM port.Įsptool.py requires Python 2.7 which is normally the default on Mac OS X. You can find it in applications, in the Utilities folder, or by entering Terminal in Spotlight. If you are a beginner, we will use the Terminal to perform all the steps of this tutorial.
