TDA4VM: Tda4+ox08b performance

Shine
Genius 13655 points

Part Number: TDA4VM

Hello Champs,

HW: TDA4VM+ox08b

SW: ti-processor-sdk-rtos-j721e-evm-08_04_00_06

Customer prints Tda4+ox08b performance statistics information，the log shows the frame rate is 12.55 fps，the root cause maybe CAPTURE2 waster  about 79ms ,but the sensor setting is 30fps, so please help check the issue, the attachment is the performance statistics log, thanks!

    Hi Shine,

    How many channels are you trying to capture? Are all of these channels transmitting at 30fps? Because CSIRX node just processing interrupts, there isn't much processing in CSIRX node. So if your channels are async and/or its not outputting at 30fps, capture node's timing will increase..

    Hi TI expert，

    I only link   one camera capture，and the sensor setting is 30fps,Is there any other reason?

    Best Regards

    Hi Renhui,

    In the TDA4+ox08b statement, what is ox08b? Is it some sensor that you are trying to enable on TDA4 device? 

    Also are you building vision in debug profile? or is Linux OpenVX application getting blocked due to some reason? 

    Can you capture timestamp in the driver callback and see if the callback is received at every 33ms? This will confirm if the sensor is outputting at 30fps.

    Regards,
