Hi, Ti
I would like to ask you a question. I am debugging ub960-ub953-imx390 now. The sensor has been loaded successfully, but how to capture pictures or video streams? Can you tell me some commands？

    您好，Alice

    我是想适配ox03c10，在imx390的驱动上修改为ox03c10的驱动，我按照您提供的FAQ中的方式，在最后一步test camera中，执行./apps_python/app_edgeai.py configs/imx390_cam_example.yaml，没有成功，log如下：

    您好，

          这种报错通常是格式不匹配， 下面的用户手册的配置您参考一下

          Demo Configuration file — Processor SDK Linux for Edge AI Documentation

         如前面回复，不同的评估板适用的SDK不一样。

           类似的问题的帖子请参考

         TDA4VM: About some problems encountered by OX03C10+MAX96717+MAX96712 - Processors forum - Processors - TI E2E support forums

    您好，Alice

          请问下，edgeai-tiovx-kernels等模块应用程序应该在哪里编译，因为我在虚拟机上编译会报错，却很多头文件，但是在开发板上可以编译通过。这个是为什么呢，那假如应该是在开发板上编译，那我改动的代码从哪去保存呢

        谢谢

    您好，

          我查看了文档，但是文档中描述的似乎也是开发板端的改动和编译，一旦我重烧系统，我的改动就丢了吧，所以我怎么把我的代码保存到我pc端呢，谢谢

    您好，

        就比如说，我在/opt/edgeai-tiovx-modules和edgeai-gst-plugins里增加了ox03c10的sensor相关代码，在板子上跑通了，但是这个代码怎么在我的pc端commit保存呢
