Part Number: TDA4VEN-Q1
Other Parts Discussed in Thread: AM62P
Hi,
We are currently adapting four ISX031 cameras on the TDA4-Ven chip, using the MAX96724 deserializer and MAX96717 serializer. I am currently using SDK version 10.1. The camera specifications are 1920x1536, UYVY422 8-bit, at 30fps. While the 4-channel video stream outputs correctly most of the time, we are experiencing intermittent failures where the video output is completely lost. To isolate the issue, we conducted the following comparative tests: Sensor Swap:
Replacing the ISX031s with four Ox01f10 sensors works perfectly without any issues.
Reduced Channel Count: Using three or fewer ISX031 cameras simultaneously outputs images without any problems.
Frame Rate Test: Lowering the frame rate of the four ISX031 cameras to 12fps still exhibits the issue. Therefore, we believe this is not a bandwidth limitation.
Kernel Version: We attempted to port the driver to kernel version 11.2, but the adaptation was unsuccessful due to significant kernel version differences.
Could you please provide some insights or suggestions on what might be causing this intermittent failure specifically with the 4x ISX031 setup?
