    Question: What is Bulkloop.exe and What Does it do?



    This is a bulk loopback test application that exercises the EZ-USB FX2 bulk endpoints. This test consists of a Windows application that may be used to loop data to and from any device using the general purpose driver that supports bulk endpoints. EZ-USB AN21xx, EZ-USB FX, and FX2 are all supported by the same front-end test program. The device under test must have loopback firmware loaded such as bulkloop.hex (see the bulkloop example program in c:\cypress\usb\examples\fx2\bulkloop).
