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

Hi Maik,

Take a look at the server code. If you start the server in debug mode it just accesses a Tcl variable. Use that mode to debug what the clients are doing.

Start with just one client, and then check that it works. If you start a second client and it breaks, the issue could be related to the server handling of multiple clients.

At some level this type of debugging gets too complicated ... not that using clients and servers is hard, but that Altera does not provide sufficient information to "design" everything nicely.

If your hardware has a UART or FTDI interface, then you can write actual client/server code that will be more robust than using Altera's Tcl interfaces - some of which are broken and useless due to their use of Java.

If you do want some advice on how to implement your system, feel free to ask here on the forum, or if you do not want to discuss your project in public, send an email to my forum name.

Cheers,

Dave
