Xilskey functionality on A53 Linux

Hi, I was wondering if PUF registration can be done from Linux. There's an SDK example program called "xilskey_puf_registration" which only works as bare metal on the R5 or A53. The program converts a red key to a black key and outputs the syndrome data to use when creating the boot image. I know Linux has an AES driver, but I don't think it allows registration or regeneration of the PUF. Any suggestions? (The reason for wanting this functionality is for the convenience of automated boot image builds.)

Re: Xilskey functionality on A53 Linux

There are few different posts on this topic. Currently the answer in NO but Xilinx is exploring the possibility to add this feature. Possibly second half of 2020 but I can't promise anything.

Right now the official way is to do it standalone.

Don’t forget to reply, kudo, and accept as solution.
