SPI on OMAP-L138 LCDK Expansion header schematic

Hi,

I wish to use SPI on the OMAP-L138 to communicate with an external board (a CAN controller).

Looking at the schematic for the board, J15 has the following connections:


SPI1_SCSn_7, SPI1_SCSn_6, SPI1_SCSn_1, SPI1_SCSn_0

and

SPIO_SIMO, SPIO_SOMI, SPIO_CLK, SPIO_ENAx

Firstly, there are no SPIO pins on the processor, only SPI0 and SPI1 - is this a typo, should this read SPI0?


Secondly, am I correct in thinking that SCSn pins are the chip select pins? If so, is the label correct when it says they are for SPI1? It does not make sense to bring the chip select pins for SPI1 out to this header, if the 'main' SPI pins are for SPI0.


I'm hoping there is a typo somewhere, because it would be very unfair to not bring out the chip select pins for the same SPI peripheral on the header!

Many thanks,

Chris
