Hmm good question, it fails a bit later on during the boot just before __enable_mmu. But I just tried commenting out the setting of bit 11: @orrlt r10, r10, #1 << 11 @ set bit #11 And just trying to write the unmodified diagnostic register also makes it fail. So yeah it seems to be related to the secure crap instead :( Regards, Tony -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
