Error on non-volatile encription for Arria10

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

    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.
