Other Parts Discussed in Thread: AM62P
部件号: AM62P
您好、
目前、我正在调整 AM62P 平台上的 ISX031 摄像机、配置为:1920*1536 分辨率、UYVY422_8 位格式、30fps 帧速率、使用 MAX96717 串行器和 MAX96724 解串器。 单通道视频流开发已经完成、但在验证多通道视频流时、系统会阻塞、无法捕获图像。
2.我怀疑这是一个 MIPI 带宽问题。 解串器的当前 MIPI 带宽为每通道 2Gbps(4 通道)。 应该如何调整 CSIRX 或 SOC 侧?
3.我已经尝试过修改 链接频率 1000MHz 或任何其他高于 800MHz 的值、但始终导致如下所示的错误。
有人帮我吗? 谢谢!
