To test the USB communication in the Reference Architecture case is necessary:
...
To completely test the Reference Architecture is necessary:
The procedures are the following.
.bit or .mcs direct download iMPACT, OpenFut or OpenFutNet | Procedure SDK: opening and update SDK project only Compile and link time less than 1 minute. | Procedure XPS+SDK: opening and update both XPS and SDK projects Resynthesis of reference HW could take from 10 minutes to 1 hour(1) | |||
---|---|---|---|---|---|
| |||||
Update XPS project from an old version to a new one | |||||
Open SDK project and (if needed) update the SDK project from an old version to a new one | Recreate SDK project using the new exported HW project | ||||
Generate a new link script | |||||
Download the bitstream to the FPGA | |||||
Run the demo project | |||||
Check the fiirmware of FX2 microcontroler | Run the demo project|||||
USB communication tests + DMA tests |
(1) It depends on which computer is used (workstation, regular PC or low-end PC).

To use the demo project without the XMD UART, you need to use "RS232" instead of "debug_module" as standard in/out port. Otherwise the application running on the Microblaze processor freezes if you disconnect the XMD. To accomplish that you need to set up the Microblaze "Software Platform Settings".
