[参考译文] DS90UB954-Q1EVM：排队的 v4l2缓冲区包含损坏的数据(1843200字节)

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1058452/ds90ub954-q1evm-dequeued-v4l2-buffer-contains-corrupted-data-1843200-bytes

大家好、

          我们正在研发配备 AR0521摄像头的 TI DS90UB954和 TI DS90UB953 EVK。 在串行器侧、我们使用两条差分数据线连接了 ar0521摄像头。 加载的摄像头驱动程序没有任何错误(检测到摄像头 i2c 地址)并创建了/dev/video0节点。 但是、在尝试使用以下命令录制视频时、我遇到了一个错误。 请检查以下日志。
