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

Hi Maik,

Here's the procedure I just used to check the server+client tcl code.

1. Start a NIOS II IDE Console (Cygwin shell) and start the server

quartus_stp -t jtag_server.tcl 2540 1

2. Start a NIOS II IDE Console (Cygwin shell) and start the first client

quartus_stp -t jtag_client.tcl

3. Start a NIOS II IDE Console (Cygwin shell) and start the second client

quartus_stp -t jtag_client.tcl

4. Write and read to addresses from both clients, and look at the messages in the server console

For example, in the first client write (addr, data) = (0, 1111), (1, 2222), (2, 3333), (3, 4444)

Then in the second client, read all of those addresses.

It worked fine for me.

When using a JTAG-to-Avalon device, you might want to make sure the addresses are 4-bit aligned, eg., write to addresses 0, 4, 8, 0xC, etc.

Have you confirmed your JTAG-to-Avalon-MM bridge interface works with SystemConsole?

Cheers.

Dave
