I do not see even a single line of log even from bl1. Would that mean the SW stack/Yocto doesn't support armv8.2 for fvp-base model platform? > > If you’re using a recent meta-arm which sets the base-fvp to v8.4 cores, then you didn’t also tell TF-A to use 8.2 and it might have been trying to use 8.4 instructions.
