Hi,

I am designing in the two 70 pin connectors to provide future expansion for an existing AT91SAM7X board for an embed application.  It's hard for me to tell from the existing documentation how the J1 and J4 connectors map to the OMAP CBB chip.  A table with that mapping would help.  (Or if I could know which I/O mode the OMAP is in for the J1 and J4 reverences provided on the website.)

I need the following resources to replace what I'm using on the ARM7:

2 Async serial interfaces (RS-485)
2 SPI with CS's
40 GPIO

Thanks in advance, Bill
