Arria10 HPS secure boot from FPGA

Hi, For bootstrapping in production and as a rescue mechanism for 'bricked' boards, we use an FPGA image, with a U-boot image embedded in ROM. The FPGA image is loaded over JTAG and forces the HPS ...

Hi RVCA,


From consulting the team so far I didnt get to know any of the method to boot up from the ROM of FPGA. I afraid the Boot ROM may not support that. Any particular requirement reason that you are going to boot from the ROM of FPGA instead of other flash location?


Thanks.

Regards,

Aik Eu

Hi aikeu,

We always boot from a ROM embedded in an FPGA image to bootstrap fresh boards on the production line. This is before we flash the keys and enforce secure boot.

We would like to have a way to re-start this process in case a problem occurs during production test. Flashing the secure fuses cannot be re-done, but it seems there is no way to rescue a board if it has issues booting from flash, once secure boot is enabled.

I am also in contact with Intel Premier Support now to get a final answer.

Kind regards,

Robbe
