Built on top of the RTOS, Linux, and Non-OS, TuyaOS is a distributed and platform-agnostic IoT operating system.
Backed by the TuyaOS kernel and various development components, TuyaOS is designed to tackle the heterogeneity of platforms, systems, protocols, and applications in order to enable quick and reliable integration, interconnection, interoperability, and compliance. The tiered and plug-and-play architecture design allows you to quickly tailor a development framework based on your hardware resources and use cases hence reducing the cost of development with high cost performance. Tuya’s proprietary things data model and software bus allow all TuyaOS-based products to be interconnected.

Some package dependencies need to be installed before compiling.
$ sudo apt-get install build-essential wget git python python3 libc6-i386 Do not install libc6-i386 will prompt arm-none-eabi-gcc not found, install libc6-i386 and first call compile clearup command to clearup the generated intermediate files, then compile.
The compile project is in the apps directory, you can quickly compile, burn, and run the process through tuyaos_demo_examples. Use the following command in the root directory to compile:
$ sh build_app.sh apps/tuyaos_demo_examples tuyaos_demo_examples 1.0.0apps/tuyaos_demo_examples：compile project path
tuyaos_demo_examples：compile project name
1.0.0：The version of the current compilation firmware
You can clear the compiled intermediate files with the following commands:
$ sh build_app.sh apps/tuyaos_demo_examples tuyaos_demo_examples 1.0.0 cleanThe compiled bin file is in apps/tuyaos_demo_examples/output/1.0.0. The file name and its functions are as follows:
| Firmware name | Usage scenario |
|---|---|
| tuyaos_demo_examples_QIO_1.0.0.bin | Production firmware，includes bootLoader and application firmware, can be used for new module production |
| tuyaos_demo_examples_UA_1.0.0.bin | Application firmware，not include bootload |
| tuyaos_demo_examples_UG_1.0.0.bin | OTA firmware，can upload Doodle cloud platform to complete OTA function of the device |
Use bk_writer_gui.exe for serial port burning, burning instructions refer to T2 burning Instructions
The current application provides rich examples and industry application product development kits to help developers quickly familiarize themselves with TuyaOS software development based on T2 chips.
