[参考译文] SK-AM62A-LP：如何启用 IMX327摄像头传感器

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1479258/sk-am62a-lp-how-to-enable-imx327-camera-sensor

工具与软件：

您好！

我们一直在尝试使用 IMX327摄像头运行电路板、但没有成功。 基于此 链接、 我们已决定按照 IMX290摄像头的安装步骤进行操作、请查看基于现有 IMX219覆盖文件的附加 overlay .dtso 文件。 首先、我们尝试编译文件并将其上传到板中、然后在 Enable a New CSI-2 Sensor 指令后构建下一个全新的内核。 在这两种情况下、电路板均无法检测到摄像头。 为了澄清、.dtbo 文件可在电路板上找到、我们更改了 uEnv.txt 文件以将其包含在内。
