Question about AN8694_Bulk in Read data does not meet expectations
Hi, I have read through the document of the application note AN86947 - Optimizing USB 3.0 Throughput with EZ-USB® FX3™ there is a subproject GpifToUsb which is used to measure the performance of GPIF to USB Bulk data transfers.
This example continuously reads data from a bare-boneGPIF II interface and sends it to the USB host through an IN endpoint, without any firmware intervention.
My PCB has a FPGA(not configurated)connect with the FX3's GPIF
When I run the GpifToUsb and use the USB Control Center to read from the Bulk in enpoint 0x81,I got "06 00 00 50"Infinite loop Instead of the expected "00"loop.
Can someone help us explain what?
