the print is :

mipierr:frmErrCnt=0,crcErrCnt=0,mdlErrCnt=4003D50C,ctlErrCnt=4000794C,eidErrCnt=4000A778,recrErrCnt=0,unrcErrCnt=0,recSyncErrCnt=0,unrSyncErrCnt=0

you see some format is print error,and the print format sometimes is print ok, some times error.

How to slove it?

  I use cx3 on ARM(RK3399 Ubuntu),  the sensor is ov9282, 1280x800 @ 15fps, it always block in a minutes(about 30 minutes), there is no error, but can't get any frame data.  The log is as below. "commit_num" is added by myself, to count the times of data commit to usb endpoint. When it is block, there is no error,  and the "commit_num" also not update.

  But on PC, also Ubuntu OS, it always ok.

Is there anyone have this issue, and give me spme suggestion?

Hi everyone.

I'm using CX3 to transfer image data to Jetson Xavier board through USB port.

I'm using cyusb_bulk_transfer function and there is a problem of timeout.

When I check the packet transfer time, each packet tranfer usually takes 300 us but sometimes it takes 280000 us.

It causes severe frame drops of my system.

Is this due to CPU resources or an intrinsic problem of bulk data transfer?

Thank you in advance.

Hello

I'd like to interface FX3 with an Standard resolution S-VIDEO encoder (Analog device ADV7280A)

I need some advice in order to modify the UVC AN75779 to works with a Interlaced video signal.

At the moment I'm able to get a 720x288 video.

I think there are some modification to do in the payload header and to the configuration descriptor.

I have is motor driver with interface I2C. I want comunication with motor driver by USB controller, which have interface USB3.1 or USB3.0

Why does enabling the USB_DEBUG_INTERFACE in the AN75779 code using SDK version 1.3.4 let the firmware run under the debugger when the debugger has problems with it disabled.

This question is not on how to use the USB_DEBUG_INTERFACE or how it works;

This question is to understand what else may be affected due to a known issue with the debugger in 1.3.4 as discussed in Community Post FX3 SDK version 1.3.4 won't put breakpoints while running
