Interface notes
---------------
**SPI** Currently not working
**SPI**
Two SPI buses are available, with one chipselect each. Pins listed are MRAA
numbered pins. Other chip selects are available if enabled in BIOS/EEPROM but
cannot be enabled as BIOS options. You will need the spidev kernel module
loaded, Ostro-XT does this by default.
Bus 0 (32765)
MOSI = 2
MISO = 4
CS = 6
CLK = 10
Bus 1 (32766)
MOSI = 67
MISO = 69
CS0 = 59
CS1 = 61
CLK = 65
(remove 40 from numbers to get pin header number for pins on low speed header
2)
**UART** Some pins are labelled as UARTs but are not configured in BIOS as UART
so only available UART is on the FTDI header
