Tracing all 4 MCSI signals starting from the Calypso MCSI_TxD: Calypso ball L10, L1 trace goes to (3829,474). The trace on L2 gets lost in the edge grind-down damage. MCSI_RxD: Calypso ball M10, no visible trace on L1 - perhaps there is a micro-via under the ball? The ball pad coords are (3841,499). Looking at L2, the micro-via hypothesis seems to be correct: a trace from those coords goes in the same bunch as the MCSI_TxD. But then it gets lost in the damage too. MCSI_CLK: Calypso ball N10, L1 trace goes to (3898,369). L2: joins the same bunch with MCSI_TxD and MCSI_RxD, then gets lost in the damage. MCSI_FSYNCH: Calypso ball K9, L1 trace goes to (3865,524). L2: same story as the others.
