Dear experts,
Now I am facing with a hardware issue on writing encription. When I wrote a non-volatile encription key with ekp-file to Arria10 device, it caused writing failure on Programmer. After that, I checked port status, and found TDO was always 1.8V, Vcc for JTAG. Since TDO was always remained as 1.8V, I couldn't use JTAG port. Once I used the target ekp-file for another device, and it worked correctly. I revised file-name only for the ekp-file on this time. Does anyone have any idea about such an issue? Thanks, Tetsuya- Tags:

Guys,
I found a root cause. My new assembled board had mistake on component for 0.9V regulator. It would resolve by correct part mount. Thanks. Tetsuya
