Yes, your info made me remeber another spot. I discussed this error once with a mastership student and he told me that a possible reason to this is when the communication between some Nios CPU and the Nios IDE falls. It was exactly what happen with you, wasn&#39;t it? However may exist other reasons to this communication falls, such as when a Nios CPU, or the Avalon switch fabric, is so busy so that stops sending messages to jtag_debug_module. However I&#39;m not being able to identify what component in the SOPC builder could be answerable for this.
