| # Matter MW320 All Clusters Example Application |
| |
| The example is based on |
| [Matter](https://github.com/project-chip/connectedhomeip) and the NXP MW320 SDK |
| to demonstrates device commissioning and cluster control over a low-power, WiFi |
| 802.11n network. |

| ## Introduction |
| |
|  |
| |
| The example targets the |
| [NXP MW320 WiFi Micro controller Soc](https://www.nxp.com/products/wireless/wi-fi-plus-bluetooth/88mw32x-802-11n-wi-fi-microcontroller-soc:88MW32X) |
| development kit. |
| |
| ## Building |
| |
| Building the example application is quite straightforward. It can be done via |
| following commands: |
| |
| ``` |
| $ cd examples/all-clusters-app/nxp/mw320/ |
| $ git submodule update --init |
| $ source third_party/connectedhomeip/scripts/activate.sh |
| $ gn gen out/debug |
| $ ninja -v -C out/debug |
| ``` |
| |
| Example application binary file "chip-mw320-all-clusters-app.bin" will be |
| generated under directory "out/debug". |
| |
| Note: |
| |
| 1. "git submodule update --init" only needs to be issued for the first time in |
| order to download MW320 SDK for Matter. |
| 2. "source third_party/connectedhomeip/scripts/activate.sh" can be omitted if |
| your environment is already setup without issues. |
| |
| Tinycrypt ECC operations: |
| |
| Note: This solution is temporary. |
| |
| In order to use the tinycrypt ecc operations, use the following build arguments: |
| |
| ``` |
| $ gn gen out/debug --args='treat_warnings_as_errors=false mbedtls_repo="//third_party/connectedhomeip/third_party/nxp/libs/mbedtls" chip_crypto="tinycrypt"' |
| ``` |
| |
| ## Flashing |
| |
| Connect MW320 to Ubuntu USB port and open Linux text-based serial port |
| communications program at second USB interface (/dev/ttyUSB1): |
| |
| ``` |
| $ TERM=linux minicom -D /dev/ttyUSB1 -b 115200 |
| ``` |
| |
| Prepare MW320 download firmware image: |
| |
| ``` |
| $ ln -sf third_party/connectedhomeip/third_party/nxp/mw320_sdk/repo mw320_sdk |
| $ mw320_sdk/tools/mw_img_conv/bin/mw_img_conv mcufw out/debug/chip-mw320-all-clusters-app.bin out/debug/all-cluster-mw320.mcufw.bin 0x1F010000 |
| $ cp out/debug/all-cluster-mw320.mcufw.bin mw320_sdk/mw320_matter_flash/Matter/. |
| ``` |
| |
| Install OpenOCD (Open On-Chip Debugger): |
| |
| ``` |
| $ sudo apt-get install openocd |
| ``` |
| |
| Flashing firmware image to MW320: |
| |
| ``` |
| $ cd mw320_sdk/mw320_matter_flash |
| $ sudo python2 flashprog.py -l Matter/layout-4m.txt --boot2 Matter/boot2.bin --wififw Matter/mw32x_uapsta_W14.88.36.p172.bin --mcufw Matter/all-cluster-mw320.mcufw.bin -r |
| ``` |
| |
| After MW320 is reset, console will allow you to enter commands: |
