Start by comparing the attached LicheePi4A Linux 6.6 logs produced with upstream OpenSBI and revyos OpenSBI, then inspect the referenced Armbian build commit 3098c2f0 and the th1520-v6.6.3 and th1520-v1.3.1 branches. Done means identifying why secondary CPUs fail with the upstream binary and documenting or implementing a compatible OpenSBI update for TH1520.
