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 Maik,

I first have to start the jtag_server.tcl and after that I can use the jtag_client.tcl to access the JTAG to Avalon Master Bridge in my FPGA design, right?

Yes. I'm pretty sure I made the client as simple as possible, i.e., if the server was not there it does not keep retrying the connection. You could easily add retry functionality, but I would recommend putting a delay in between retries.

And in order to get the server connected to the desired device on my JTAG Chain, I have to edit the jtag_open function and use device 2 instead of 0, right?

The indexing starts from 0, and since you want to access the second device, you will want index 1.

After that I should just be able to access the avalon slaves via JTAG in my FPGA with the jtag_client software, right?

Yes, that sounds correct.

Cheers,

Dave
