Error: Connected system ID hash not found on target at expected base address

It s ok don't worry if you have followed any tutorial..the design are all correct. I have used them.. I know there is a problem of the error you are getting.I had the same problem but there is a work around to it.

First check

Do you have a jtag component in ur sopc..if not add it..did you donwload the hardware design in the fpga??

Donot terminate the programmer open sopc ,the time limited which is running.

Go to eclipse select perspective..goto debug configurations..check if u can see the cable which u are using to download..now debug it..donot run it..

I don't know the cause of the error but it woorks fine,there will be a warning of terminated but don't worry you can run it..use debug
