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:

RK3308

获取 Client ID:

RK3308

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

RK3308

● 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

RK3308

RK3308

选择[1],然后按空格选择上 alexa client sdk

RK3308

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
