Building the firmware

As only the application are concerned, we can use the online firmware building service at http://nodemcu-build.com to get the firmware. It’s quite straightforward to build the firmware on this website, by just selecting the modules to be included. However, it won’t work if too many modules are selected.

Flashing the firmware

First make sure that the usb serial firmware is properly installed on the system.
I used this tool to flash the firmware:

baudrate: 115200 (others might also work), dual IO, …

Using NodeMCU-Tool

NodeMCU-Tool: https://github.com/andidittrich/NodeMCU-Tool
Before installing NodeMCU-Tool, make sure that you have Node.js >= 7.6 installed on your system.

Installation

sudo npm install nodemcu-tool -g
This will install NodeMCU-Tool globally on your system.

Verifying the installation

nodemcu-tool --version

Creating the file system

nodemcu-tool mkfs --port=/dev/tty.wchusbserial14410 --connection-delay 300 --baud 115200
outputs:

(node:13754) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)
[NodeMCU-Tool]~ Connected
[device]      ~ Arch: esp8266 | Version: 3.0.0 | ChipID: 0x2aecbf | FlashID: 0x1640c8
[NodeMCU-Tool]~ Uploading "helloworld.lua" >> "helloworld.lua"...
[connector]   ~ Transfer-Mode: hex
[NodeMCU-Tool]~ File Transfer complete!
[NodeMCU-Tool]~ disconnecting

Uploading code

nodemcu-tool upload --port=/dev/tty.wchusbserial14410 --connection-delay 300 --baud 115200 helloworld.lua
outputs:

(node:13754) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)
[NodeMCU-Tool]~ Connected
[device]      ~ Arch: esp8266 | Version: 3.0.0 | ChipID: 0x2aecbf | FlashID: 0x1640c8
[NodeMCU-Tool]~ Uploading "helloworld.lua" >> "helloworld.lua"...
[connector]   ~ Transfer-Mode: hex
[NodeMCU-Tool]~ File Transfer complete!
[NodeMCU-Tool]~ disconnecting

Running the helloworld

nodemcu-tool run helloworld.lua --port=/dev/tty.wchusbserial14410 --connection-delay 300 --baud 115200
outputs:

(node:13764) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)
[NodeMCU-Tool]~ Connected
[device]      ~ Arch: esp8266 | Version: 3.0.0 | ChipID: 0x2aecbf | FlashID: 0x1640c8

构建固件

由于只关心应用程序，我们可以使用在线固件构建服务 http://nodemcu-build.com 来获取固件。在这个网站上构建固件非常简单，只需选择要包含的模块即可。但是，如果选择了太多模块，它可能不起作用。

刷写固件

首先确保 USB 串行固件已正确安装在系统上。
我使用了这个工具来刷写固件：

波特率：115200（其他波特率也可能适用），双重 IO，…

使用 NodeMCU-Tool

NodeMCU-Tool：https://github.com/andidittrich/NodeMCU-Tool
在安装 NodeMCU-Tool 之前，请确保您的系统上已安装 Node.js >= 7.6。

安装

sudo npm install nodemcu-tool -g
这将在您的系统上全局安装 NodeMCU-Tool。

验证安装

nodemcu-tool --version

创建文件系统

nodemcu-tool mkfs --port=/dev/tty.wchusbserial14410 --connection-delay 300 --baud 115200
输出：
