https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1632648/sk-am62-lp-imx219-not-able-to-enabled-camera-to-display-pipeline-using-gstreamer

器件型号： SK-AM62-LP

尊敬的团队：

我正在尝试调出摄像头、以在启动时显示流水线。

使用中的硬件：
- am62a EVM
- imx219 rasberrypi 相机
-标准 HDMI 显示屏

我使用 SDK 准备了 tisdk-edgeai-image、

步骤：
Git 克隆 https://git.ti.com/git/arago-project/oe-layersetup.git tisdk
CD tisdk
./oe-layertool-setup.sh -f configs/processor-sdk-analysis/processor-sdk-analytics-11.01.07.05-config.txt
CD 版本
Machine=am62axx-EVM 位 bake tisdk-edgeai-image

输出在 DEPLOY-ti/Images/am62axx-evm/tisdk-edgeai-image-am62axx-evm.rootfs.wic.xz 中生成

我正在使用 SD 卡进行引导。使用以下命令将编译版本加载到 SD 卡：
sudo bmaptool copy --nobmap tisdk-edgeai-image-am62a-evm-11.01.07.05.rootfs.wic.xz /dev/mmcblkX

通过添加摄像头 DTS 叠加来启用摄像头。更新 uEnv.txt

启动后、我看到创建了 camear deivce 节点。但我无法运行 gstreamer 命令。

嗨、Avijit、

它是否支持与我们 SDK 一同打包的默认映像？

https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-D37Ls3JjkT/11.01.07.05/tisdk-edgeai-image-am62a-evm-11.01.07.05.rootfs.wic.xz

我刚刚在 AM62A 上运行了以下命令、运行正常。

您好、Suren、

我现在可以通过添加 k3-am62a7-sk-edgeai.dtbo 覆盖层来使摄像头正常工作。

感谢您的帮助。
