Hi,

Your SOPCB system looks right, I might connect the JTAG master to the RAM as well (it would be useful for testing). SOPCB will tell you what can be connected to what - if there is no hollow dot then you can't connect it.

The JTAG to Avalon Master Bridge contains all the pieces you need - all the components you mention are inside it.

You can set the registers from Nios or from SystemConsole - with the PIO component whatever wrote last will win.

You don't need to connect the JTAG master to the JTAG UART (in fact you should not as the JTAG UART slave will be confused if accessed by two masters).

Regards
