Secure BOOT Genesys ZU3G




I am trying to do secure boot on the GenesysZU3G. The following is a comment in fsbl_%.bbappend for the OOB image:


# Exclude Secure feature from FSBL until -O2 compilation bug is fixed

Was this issue ever resolved? I tried removing the FSBL_SECURE_EXCLUDE, but I get build errors.

If I build the fsbl locally using Vitis 2020.1 with FSBL_SECURE enabled, everything boots fine but the kernel hangs.     


Although it looks like a device tree issue, I don't think it is because if I replace the FSBL I built with Vitis 2020.1 with the one that builds with the OOB, it boots to the command prompt and doesn't hang. The so issue is definitely being caused by the FSBL.
