Hi @FrogWeapons,

Thank you for posting in Intel community forum, hope this message find you well.
Can we know what board are you using? And also the type of USB blaster cable is being used to connect to the board?
Also if convenient, perhaps you can share a screenshot of the design you have for us to better understand the situation.

Warm regards.
BB

Hi BB, the information I can give is:

- Arria V

- Quartus 16.1

- Using internal block RAM only for NIOS.

- Just as standard "Altera USB-Blaster" - although probably not too relevant as the failure event happens when connected or not connected !

We have a watchdog in the system, but disabling this has no effect - I also tried forcing an infinite loop to see it the watchdog was causing trouble.

Whatever is killing the NIOS seems to be killing the "jtag debug module" - see attached image "Nios lock"

Thanks.
