ModeratorHi @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.

New ContributorHi 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.
ModeratorHi @FrogWeapons,
Apologies for the delayed in response, may I know how did you program your devices?
Here is some guide on programming the onchip memory which might provide some insight.
Did you managed to program your devices with the 'memory test' template and did the same issues occur?
On a separate note on watchdog, yes it will cause some issues when you are trying to run program in debug mode, hence do not enable watchdog timer if you are debugging. (details explanation can be found here)
Best Wishes
