I have followed the Xilinx doc, xapp1175, to set up authentication and encryption. Authentication has been set properly and is mandatory. I am able to flash images that apply RSA to the FSBL, and they work correctly.
Now I am trying to set up encryption. This is not working.
I am unable even to read the Efuse PL key. The error code indicates a JTag initialization problem. There has been another post on this topic in this forum 3 years ago (TE0720 eFuse programming with TE0703 carrier board), and the person was able to resolve his problem by putting a sleep into one of the xilskey functions. I have tried that without success.
Is there a Trenz reference project that addresses the programming of the EFuse PL key? If not, is it possible to pay for customer support to get me through this? I am completely stymied.
