Audio interface[edit | edit source]

There is no directly available Audio interface on the Evaluation Kit, two SAI and one SPDIF full duplex interfaces are available on the expansion connector.

Description[edit | edit source]

The SAI and SPDIF interfaces are available on the Evaluation Kit at the connector J8.

J8 is a 20x2x2.54mm pin header expansion connector that delivers many interfaces unused on board.

Device mapping[edit | edit source]

UART3 is mapped to /dev/ttymxc2 device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

Device usage[edit | edit source]

To connect to the debug serial port:

  1. connect the DB9 adapter bracket to the J22 connector on the SBCX board
  2. connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)
  3. start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1
