I have an OMAP4430 design and for some odd reasons, the PCB misses the pad corresponding to the ball AG17 of the OMAP4430. Assembly has already been done and everything is functional including the USB host feature. It's worth noted that AG17 is in the middle of all the USBB1_ULPITTL balls. But those balls can be muxed in other features.
In the data manual, this ball is simply mentioned as VSS ("main and slicer ground") but it doesn't say anything more.
Some VSS balls that are specific to a sub-system are sometimes marked in the data manual. For instance, ball H10 is marked as the ground of the USB OTG phy.
I would like to know if this ball AG17 is connected to the other main ground balls or if it's isolated and linked to the ground of a specific sub-system.
It's an after-assembly question to assess any impact. It will obviously be fixed in next revision.
