The following registers do not show up in the Registers Window for the C6657:
EMIF16
SPI
McBSP0
McBSP1
MDIO
uPP
There may be others. At least one of these was reported over a month ago. What needs to happen to get this fixed? It's very difficult to debug a McBSP using the Memory Browser. Furthermore the DDR3 registers are still not fixed (they read all zeros).
