MediaTek LinkIt(TM) Development Platform for RTOS provides a comprehensive software solution for devices based on the MT76x7 and MT2523x SOCs. 1. Getting started The SDK package supports GCC, Keil, and IAR tool chains. Follow the instructions at <sdk_root>/doc/LinkIt_for_RTOS_Get_Started_Guide.pdf to build your first project and run it on the HDK. Release notes are also under the <sdk_root>/doc folder. 2. Folder structure \doc -> SDK documents, including get started guide, developer's guide, software and environment guide, -> API reference manual, and SDK release notes. \doc\HDK -> HDK documents, including user guide, layout information, schematics, daughterboard information, -> BOM list. The HDK relative application notes are also in this folder, such as power measurement guide. \doc\MCU -> Chipset documents, such as chipset product brief and chipset datasheet. \driver\board -> Drivers for the development board \driver\chip -> Chipset modules, such as GPIO, I2C, Bluetooth Low Energy. \driver\CMSIS -> CMSIS interface drivers. \driver\inc -> HAL driver APIs \kernel -> OS / system service \middleware\MTK -> MediaTek middleware. Read readme.txt in each module for details. ** The SDK package downloaded from labs.mediatek.com does not include GNSS middleware. See instructions ** ** on http://labs.mediatek.com/ or the vendor's website, http://www.wpgo2o.com/getAdDownloadList?AdId=60. ** \middleware\third_party -> Open source software, such as cjson, fatfs, httpd. Read readme.txt in each module for details. \project\<board> -> Example projects of the current SDK. Read <sdk_root>/project/readme.txt for more details. \tools -> Script, generation script, gcc compiler. If there isn't a gcc compiler under the /tools/gcc folder, -> extract the tool package to the root folder of the SDK with the following command. -> 7za x SDK_VX.Y.Z_tool_chain.7z -o<sdk_root> ** Please make sure you have /tools/gcc before you build the SDK under linux environment. **
