The HDMI interface available on the Evaluation Kit at the connector J12, labelled as ''TBD:JxxxHDMI''on the bottom.

''Jxx'' J12 is a ''TBD:Mini HDMI horizontal receptacle connector-type'' header connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).

UART3 HDMI video is mapped to the corresponding device driver in Linux, depending on the device tree configuration. If this is the only video output, then the default value is mapped to <code>/dev/ttymxc2fb0</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

To connect to The associated framebuffer device is accessed in Linux through the debug serial port: # connect the DB9 adapter bracket to the J22 connector on the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1standard graphic access.
