Please let me know more details about the application
- When is the reset seen? Is it after the enumeration is completed or during the data transfer
- Also, let me know about the firmware that you are using. Is the firmware attached to the application note AN65974?
- Is the boot mode from I2C EEPROM with USB fallback or only I2C EEPROM
- Does the custom board have a UART interface to view the UART debug prints (on Teraterm)
In am application I am sending data from PC to custom board (which contains CYUSB3014 controller interfaced with FPGA) through USB3.0
-Reset is seen during data transfer
-I am using firmware version 1.3
-boot mode is from I2C EEPROM with USB fallback
-Custom board doesn't have a UART interface (uart pins are not free)
