参考固件

固件：ROC-RK3308-CC Alexa

Amazon授权

使用 Alexa Voice Service，首先你需要注册一个Amazon账号，向 Amazon 注册你的产品，并对你的 alexa client 进行授权。

第一步，按照官方指导，仔细的按照步骤，注册你的产品，并创建安全配置文件。

第二步，得到你的 Client ID 和 Product ID

获取 Product ID：

获取 Client ID：

使用流程

注意：Alexa Voice Service 不支持中文。

● 上电开机，如果没有配置网络，先进行配网。

● 将上面获得的Client ID 和 Product ID填入 /oem/AlexaClientSDKConfig.json的deviceInfo属性：

"deviceInfo":{ // Unique device serial number. e.g. 123456 "deviceSerialNumber":"123456", // The Client ID of the Product from developer.amazon.com "clientId":"YOUR_CLIENT_ID", // Product ID from developer.amazon.com "productId":"YOUR_PRODUCT_ID" },

● 执行下面命令启动 Alexa

SampleApp /oem/AlexaClientSDKConfig.json /oem/resources/

● 第一次启动需要进行认证授权，按提示打开对应网页，输入验证码进行认证即可

################################## # NOT YET AUTHORIZED # ################################## ################################################################################################ # To authorize, browse to: 'https://amazon.com/us/code' and enter the code: AT4HLU # ################################################################################################ ################################################# # Checking for authorization (1)... # #################################################

● 认证过程中，稍等几分钟后，就可以与 Alexa 进行对话，可通过呼叫“alexa”唤醒，不过大部分交互体验都要通过命令行引导。

资源

Alexa 源码目录：

SDK/external/alexaClientSDK/

Buildroot 的 Alexa package 目录：

SDK/buildroot/package/rockchip/alexaClientSDK/

Alexa 没有自启动入口，需要进入系统后自己手动启动Alexa，方法如上一节。如果需要自启动，则可以参考DuerOS。

编译方法

● 编译之前，亦可将上面获得的Client ID 和 Product ID填入SDK/device/rockchip/rk3308/alexa/AlexaClientSDKConfig.json的deviceInfo属性，这样固件就默认的带有了Client ID 和 Product ID信息。

"deviceInfo":{ // Unique device serial number. e.g. 123456 "deviceSerialNumber":"123456", // The Client ID of the Product from developer.amazon.com "clientId":"YOUR_CLIENT_ID", // Product ID from developer.amazon.com "productId":"YOUR_PRODUCT_ID" },

● 甚至可以从已经认证过的设备中，拷贝/oem/application-necessities/cblAuthDelegate.db到SDK中device/rockchip/rk3308/alexa/application-necessities/cblAuthDelegate.db，这样Alexa就会跳过认证，直接开始对话。

● 编辑 device/rockchip/rk3308/BoardConfig.mk 文件，将 OEM_PATH=oem 修改为 OEM_PATH=alexa，保存退出

● 配置 firefly_rk3308_release

source buildroot/build/envsetup.sh

选择[1]，按回车，配置成功后如下

● Buildroot配置：BR2_PACKAGE_ALEXACLIENTSDK

make menuconfig

进入图形选择界面，输入 /，跳出搜索界面如下，输入BR2_PACKAGE_ALEXACLIENTSDK，按回车进行搜索

选择[1]，然后按空格选择上 alexa client sdk

前面有 [ * ] 号，表示已经选上，然后< Save >保存，并< Exit >退出图形界面，输入配置保存命令：

make savedefconfig

保存配置，不保存的话，会在一键编译脚本中被重置

● 在编译前，如果当前仓库不是第一次编译，需要执行：

make gst1-plugins-good-reconfigure && make gst1-plugins-good-rebuild

● 最后全部编译

./build.sh
