Hi,


The IDCODE is not changeable but from the issue that you observed, the TDO is stuck at 1. which cause the readout to be 0xFFFFFFFF

I probed the TDO pin on DSO to check whether it is stuck at some logic level.

But that was not the case I was able to see the signal getting toggled, when there is programming command from Quartus-Prime through Blaster
