Hi,

I'm doing some low-level bare-metal programming with the BBB and "abuse" 
the pins on P8 and P9 for different things. Thus I multiplex these pins to 
the functions I need (mainly GPIOs).

As far as I understood it some of these pins are used for SD-card reader 
and eMMC and therefore should not be used and multiplexed to something 
different.

In case my understanding is correct: is there an overview which pins are 
affected by SD-Card and eMMC? LCD/HDMI is not used by my application and 
therefore can be overwritten but CD and MMC should work in every case.

Thanks!
