Error:Connected system timestamp not found on target at expected base address.

Hi Daixiwen:

I tried your suggestion. It gives me some new clues which I regretfully do not know how to understand.

First I tried to implement the instructions in the system console and here is the result

% set mast [lindex [get_service_paths master] 0]

/connections/USB-Blaster on localhost [USB-0]/EP2C70@1/[MFG:70 ID:34 INST:0 VER:3]/nios2_0

% open_service master $mast

% master_read_32 $mast 0 1

error: java.lang.RuntimeException: com.altera.systemconsole.internal.plugin.jtag.oci.Nios2DebugException: Can't do this while target is running

while executing

"master_read_32 $mast 0 1"

% master_read_32 $mast 4 1

error: java.lang.RuntimeException: com.altera.systemconsole.internal.plugin.jtag.oci.Nios2DebugException: Can't do this while target is running

while executing

"master_read_32 $mast 4 1"

But I have closed the SOPC and the programmer, I am very new and I really do not understand why it is running.

Then I tried to look at the SOPC but I did not find the timestamp connection.

I have attached my Printout of the SOPC file

Thank you very much for your time and attention.
