tda4系列:利用starter-kit开发板开发rtos应用
使用starter-kit开发RTOS应用
返回主目录 tda4系列
TI推出的 edgeai starter-kit （后称为SK板） 是一款针对边缘AI的开发板，针对Linux开发者设计，用户不需要了解底层RTOS的框架即可进行AI应用的开发。
与TI的官方EVM使用同一SDK进行开发，使得我们有可能通过简单的配置，将EVM的开发环境及开发步骤应用于SK板。
Linux SDK的修改
默认SK板的硬件都由Linux控制，包括DP显示， CSIRX的mipi输入，i2c接口等。
通过GPIO控制使能HDMI显示端口，但是在Linux中禁用HDMI.
您可能需要登陆才能查看下方代码
禁用相关外设, 并配置CSIRX端口至QSH-ti cam接口，而不是 raspberry pi camera 接口。
