Please note that all the signals are 0-3.3V level.
=== Device mapping ===
UART3 is mapped to <code>/dev/ttymxc2</code> The device in Linux. The peripheral is mapping depends on the used as the default serial console, both for the bootloader device and the kerneldevice tree configuration.
=== Device usage ===
To connect to 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: 115200The associated device can be accessed in Linux by standard stacks,N,8,1such as ''pulse audio'' or ''alsalib''.
