CX3 UVC reset to bootloader after serveral frames

BeCh_1049336 · ‎Apr 20, 2020

Hello,

I download my UVC firmware to RAM with control center, and preview the images with "WebcamViewer".

I encounter one problem, that is the device reset to "Cypress USB BootLoader" device after grabbing several frames and UVC device is gone.

May I ask for the help to solve this issue, is it a hardware issue or software issue?

Thanks.

Hello,

Please find the result when I tested the same with Denebola Kit:

There is no re-enumeration issue. This test was done to understand if the problem is on the hardware side or on the firmware side. As 2 different firmware showed the same issue, the problem should be on hardware side. The test that I performed on Denebola Kit confirms this. Please refer to Page 28 and 29 of the document AN70707. The link to the same can be found below:

Please check if you have followed all the guidelines properly. As this issue can also be caused by bad cables, please try testing with different cables also.

Best Regards,
