Arria10 Secure Boot : program fuses - Arria10 Secure Boot : program fuses Hello, We are currently using U-Boot 2024.04, and all components are signed (U-Boot SPL, U-Boot 2nd stage, Kernel/DTB). Our final step is to program the fuses on the Arria 10 FPGA. The alt_authtool.py script generates a file containing the hash of the root public key, which needs to be burned into the device fuses. However, we are unsure how to actually program this hash into the FPGA. Could you please advise us on the procedure to program the fuses? Which tools should we use? Are there any specific caveats or important points we should be aware of? Thank you in advance for your support.
