Does Infineon have an example that supports USB 3.x to JTAG?

A USB SuperSpeed (3.0) to JTAG would support downloading an image to an FPGA without setting up a separate channel for data to run over USB 2.0.

CY765215 is a good option to interface USB 2.0 with JTAG.

The JTAG interface of FX3 is used for debugging firmware only.
Infineon posted a Knowledge Based Article (KBA) in 2014 to documents this:

Application Note AN84868 = Configuring an FPGA over USB Using Infineon EZ-USB™ FX3 ,  describes some alternate methods to JTAG programming. Are there examples for users who want to continue to use the JTAG method with FX3?

Hello Greg,

Unfortunately, we do not have any reference example for USB 3.0 to JTAG

JTAG interface of FX3 cannot be used to program FPGA. FX3’s JTAG interface can  connect to a JTAG debugger in order to debug firmware through the CPU-core’s on-chip-debug circuitry

Rashi
