FX3/CX3 (CYUSB3065) Regarding the thread being locked:
I use this chip, and then use the routine to create a DMA to transfer UVC video data through USB3 (as a computer camera). The function has been realized, but when the device is connected to the computer, the computer enumerates the device, but the device has not been selected as a camera, the threads of the device system are not running (it looks like it is locked), including the clock interface provided by the system (CyU3PTimerCreate or tx_timer_create) and no longer callback functions. These threads will continue to run until the computer selects the device.
Note: When the device is not connected to the computer, or after the device is selected by the computer, the device threads are normal.
Please ask, where is this problem, or is there any information that can help me learn about this problem?
