ub960+ov490适配dump 图片报错

我们是自己开发的硬件, 参考的J5开发板.

摄像头点亮过程中,发现无法获取图像.

视频传输链是CSI2 -> UB960->OV490

i2C bus 2.

使用/app/bin/camera_test/j5_camera_test.sh ./hb_j5dev.json 无报错, 无图像.

使用/app/bin/camera_test/j5_camera_test.sh ./hb_j5dev.json t1 d3 尝试dump图片, 出现报错如下:

Test work vin_handle thread---running.

Test vin_handle_worker_thread Ready !

Test work cim raw data thread---running.

查看fps可以看到如下信息:

47180000.cim_dma# cat fps

cimdma pipe 0: input fps 25, output fps 0

查看cimdma_stat有如下信息, 发生sw drop

47180000.cim_dma# cat cimdma_stat |head

现在我无后续明确调查方向, 请帮看看此问题是哪里错了导致的.
