Create your own Firmware Build without IDE - stodev-com-br/Tasmota GitHub Wiki
PlatformIO is not just an IDE. In fact, all its features are accessible from the command line, and the IDE is a convenience wrapper layer around it.
Thus, we can build Tasmota using only this PlatformIO-Core, which may come handy for automated builds, or for those who feel more comfortable with the command line than with the IDE.
The steps are surprisingly simple and straightforward:
At least if you want to work in a cloud environment, but you may also choose to work on your physical machine as well.
PlatformIO is based on python, so if we use python-virtualenv, then all the dependent packages will be confined to a separate folder, so it won't even taint the OS installation.
As all of python, python-virtualenv and python-pip are available in most of the recent distros, you may pick your favourite one.
Install python and python-virtualenv, and python-pip, because we don't want to mess up the python ecosystem of the distro.
Update pip by pip install --upgrade pip, and this was the last step done as root, the rest goes as a plain user.
I used CentOS here, so if you prefer Debian-based distros, just substitute apt-get install -y ... for yum install -y ....
[tasmota_builder@jtest ~]$ sudo yum install -y python python-virtualenv python-pip
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
...
Complete!
You may update pip in the host environment, but we'll do it in the virtualenv as well, so it's optional:
[tasmota_builder@jtest ~]$ sudo pip install --upgrade pip
Collecting pip
...
Successfully installed pip-18.1
virtualenv creates a folder and prepares a whole self-contained python subsystem there.
To activate it, so that all python-related things refer to this environment and not to the system global, you need to source the file bin/activate within it.
NOTE: Not just execute in a subshell, but include it into the current one, so please note the . before bin/activate below:
[tasmota_builder@jtest ~]$ virtualenv platformio-core
New python executable in /home/tasmota_builder/platformio-core/bin/python
Installing setuptools, pip, wheel...done.
[tasmota_builder@jtest ~]$ cd platformio-core
[tasmota_builder@jtest platformio-core]$ . bin/activate
(platformio-core) [tasmota_builder@jtest platformio-core]$
Now we are ready to install PlatformIO-Core into this small virtual environment:
(platformio-core) [tasmota_builder@jtest platformio-core]$ pip install -U platformio

You are using pip version 9.0.1, however version 18.1 is available.
As it would prefer a recent pip instead of the one set up by virtualenv, so let's upgrade it:

If you want only to build, then the original repo will do, but if you want to contribute as well, then fork an own copy of the repo and clone out that one.

After changing to the working copy, we are ready to go:
(platformio-core) [tasmota_builder@jtest platformio-core]$ cd Tasmota/
(platformio-core) [tasmota_builder@jtest Tasmota]$
Now you may want to configure the sources for your needs, as described at Upload
Actually, the sources do build fine right out-of-the box, only it'll be a full build, including all the language localisation and all the build flavours as well, while you are usually interested only in one language and one build flavour only.
In platformio.ini choose the environment (or flavour, if you like) you want to build.
In tasmota/user_config_override.h fine tune the default values for the module, the wifi, the MQTT server, and so on. Refer to the Tasmota Wiki for details.
The build command itself is pio run, but as it emits quite a lot of messages (including errors if you're developing), so you may want to redirect a copy of the standard output and error to a file, so it'll be pio run 2>&1 | tee build.log.
(platformio-core) [tasmota_builder@jtest Tasmota]$ time pio run 2>&1 | tee build.log

The recent versions of PlatformIO-Core seem to parallelise quite well.
When you've changed only a few files, not everything needs to be recompiled (though the image must still be re-packed), so that minute-like build time is the maximum, usually it'll be less.
You may rebuild the firmware on a remote machine, but you must have the installer tool on the local machine where the module is connected to.
Fortunately, it's also python-based, so we can again employ virtualenv here.
If you built the firmware also on your localhost, then there is no need for a separate environment, you may quite well install esptool into that one.
Otherwise, create a virtual environment the usual way:
[tasmota_installer@lantash ~]$ virtualenv esptool

Requirement already up-to-date: pip in ./lib/python2.7/site-packages (18.1)
Now let's install esptool:
(esptool) [tasmota_installer@lantash ~/esptool]$ pip install esptool

If you've built the firmware on a remote machine, now it's time to download it into this installer environment (e.g. via scp or sftp).
IMPORTANT: For the subsequent steps your user must have the permission to write the serial port.
First of all, disconnect the bulb from the mains and wire up the serial connection and a button on GPIO0.
If this GPIO0 is connected to GND when the module gets power, it starts in a firmware-update mode, and you can then read/write its flash storage.
Switch off the power of the board, this will be the reference 'steady state' of the system.
(esptool) [tasmota_installer@lantash ~/esptool]$ esptool.py read_flash 0x00000 0x100000 fcmila_bulb_orig.bin
esptool.py v2.6
Found 1 serial ports
Serial port /dev/cuaU0
Connecting......
Now, it'll wait for the module to appear connected, so
- press the button (GPIO0 to GND), keep it pressed
- switch on the power of the board
- now you may release the button

If they don't work, then check your cabling and your serial adapter. Until you can't get this step working, don't proceed to the next one, it won't work either.
