SopC Builder n System Console

hi there,

i've already checked out for a similar threat, but there isn't.

So i have the following problem:

I want to control within a Jtag to Avalon-Master Bridge a Register where i can program a constant, all with the System Console Interface.

So i found an example the "LED Lightshow Example", introduced in the "System Console User Guide".

So that comes quite near to my problem i think. In addition i've checked out that example, all works fine. I can change the value of the constant in System Console and another LED blinks up (i have removed the accelerator)

Next i tried to build up this example on my own, to understand how things work in SOPC Builder and so on (i am a beginner on this)

So i started SOPC Builder and took a Avalon Memory Mapped Master and a Simple PIO where I modified Options to "Output Ports only" Width: "8".

I connected the Master and the PIO, all works finde.

I don't want to use this accelerator thing to have a running light, so forget this!

Then i generated the code.

Then i created a Symbol Block from the Verilog-Code

Next i created a Schematic File

where i dropped the Symbol-Block.

In the last step i assigned the PINS to the Output of the bevor created Symbol Block.

I loaded the code into my Cyclone II Starter KIt in a EP2C35F672C6N FPGA.

All works fine.

Now i want to control the LED's, i started SOPC Builder's System Console.

Then i opened the Master.

All works fine to this point.

Now i want to write a value in a register, with "master_write_8 $jtag_master 0x0 192" With the value 192 to have 2 LED's on.

But that doesn't work, it's like it try to write but nothing happens.

I couldn't use the Console anymore, so i hae to close it.

So what is the problem, could anybode help me plz? I'm new on this. :D

greetings elec
