Hey Guys,

I am new to this and I want to use the board for development.

My requirements are that I need to have the spi lines, and i2s lines exposed.

I saw spi lines exposed. Are the i2s lines exposed on the header?

Can anyone give me the document related to it so that I can study.

Well... Google gave me these:

Note that the second is still unanswered... The first shows I2S (mcasp)
output apparently sharing at least one set of SPI pins, so you would lose
some SPI for those (also lots of mention of being associated with the HDMI
output).

And pinmux tables...

Lots of mcasp stuff using the same pins as UART 4 and 5, and LCD data pins,
besides sharing with some SPI pins.
