Building a firmware binary with the Thingsquare firmware SDK
The Thingsquare firmware SDK allows developing custom firmware for running on the devices. Custom firmware applications are developed in the C programming language. The SDK can be used both to build firmware for access points and non-access point devices.
The SDK is a directory with files that contain all the necessary firmware code, include files, and a set of example C files.
The firmware SDK can be used to create both firmware binaries that can be directly flashed to the board, and firmware images that can be programmed over the air.
To use the SDK, you need to set up an environment and install a few tools. See the documentation on Installation for detailed instructions on this.
SDK directory structure
The SDK directory structure is as follows:
examples/ directory contains starting points for custom firmware applications.
include/ directory contains header files needed for custom firmware builds. Look here if you are developing your own drivers.
libs/ directory contains pre-compiled code archives that is the foundation of the firmware. This is used automatically in the build process and you don't need to do anything with this directory.
Build a custom firmware image from the examples
To build a custom firmware from the example directory, go to the
examples/ directory and run:
cd examples make TARGET=thsq-cc1310lp-etsi client-launchpad.bin
This will build a firmware image for the TI CC1310 Launchpad in ETSI (868 MHz) configuration called
client-launchpad.bin. This can be flashed to a CC1310 Launchpad board using the
SmartRF Flasher 2 tool available from Texas Instruments.
Build a custom firmware image in a user directory
The above method of building an example firmware image is not recommended for development projects.
It's better to separate the SDK from your projects and drivers, to ease version control and updating the SDK.
Instead, if you followed the installation procedure, the installation script will have set up a directory structure such as,
c:\development\sdk c:\development\projects c:\development\tools
Thus, copy the contents of the SDK
examples/ directory into eg
c:\development\projects\sdk-examples\ and update the
Makefile to point to the SDK location as follows. Edit the file called
Makefile and change the line starting with
SDK = into
SDK = ../../sdk/
Note that in the
Makefile, the path should use forward-slash (as in Linux), not back-slash (as in Windows), even if you are using a Windows computer.
Now it should be possible to build a custom firmware in the new directory with the command,
make TARGET=thsq-cc1310lp-etsi client-feather.bin
(Note that the value after
TARGET= reflects the customer base hardware platform and may need to be changed according to the hardware you are working with.)
