Agilex 7 eFuse programming failed - "certificate is invalid"
Using Quartus 23.3, I successfully programmed the eFuses on an Agilex 7 FPGA once, but have failed ever since with same and different boards, and the same and different eFuse files. Getting invalid certificate error with no other information. Is this a licensing issue? Our Quartus Prime Pro license is valid.Solved1KViews0likes3CommentsRe: quartus_sign fails to generate signed ccert
Hi @Farabi , I was able to get help from Intel via our FAE. Basically the answer was the permission settings (should have been 0x40) which are part of the "Security Methodology for Intel FPGAs and Structured ASICs User Guide". However, this document is restricted. But for others reading this post, the correct settings were actually part of the " Intel Agilex® 7 Device Security User Guide", Page 33. I will close this case. Thank you.2KViews0likes0Comments
