Target is broken and needs to be reset

I get this error message when trying to stop the Nios II processor in System Console (so I can write directly to memory). 

 

 

% processor_stop $mypath 

error: java.lang.RuntimeException: com.altera.systemconsole.internal.plugin.jtag.oci.Nios2DebugException: Target is broken and needs to be reset 

while executing 

"processor_stop $mypath" 

 

Does anyone know why I would be getting this message and how to prevent/fix it?

This message means that the target processor didn't go into debug mode when it was asked to. The most common reasons for this are: 

 

  • You did not close timing on the hardware correctly. If Quartus give you any critical warnings or worse then fix them 

  • Your clock is not running 

  • Your reset is permanently asserted 

  • The instruction or data bus attached to the processor has locked up because of a bad slave 

 

I suggest checking them in the same order I wrote them (least to most work to check)
