Tutorial: Using the USB-Blaster as an SOPC/Qsys Avalon-MM master

Hi all, I've put together a tutorial on how to use the Altera JTAG-to-Avalon-MM master and Altera Verification IP Avalon-MM BFM Master under both SOPC builder and Qsys. http://www.ovro.cal...

Hi Dave,

yes, I managed to start the server succesfully and let it connect to the JTAG Master interface in my design.

I also managed to connect the client to the server.

Unfortunately, I get an "Invalid command from the client" error when I try to send write requests. When I try to send read requests, the client GUI freezes.

Attached is a screenshot of the client/server running with the mentioned error.

In my GX FPGA, my component is connected to the JTAG to avalon Master Bridge as it is connected to the HPS in the SX FPGA, where the communication with my custom component just works from the HPS/Linux interface.

I also attach a screenshot of my system. I am also not able to access the xcvr or reconfiguration component on their avalon slave interfaces...

I looked for that error message in your server source and found that it was not even transmitting anything to the JTAG interface, because it already had problems before the actual write command. But I don't know, if this is the correct interpretation of the source code.

Maybe you can help and tell me what I am doing wrong, here.

Thanks,

Maik
