The Console interface is available on the Evaluation Kit at the connector ''TBD:Jxxx''J35.

''Jxx'' J35 is a ''TBD:connector-type'' 4 pin (4x1x2.54mm) header connector for the RS232 two-wires UART3 UART2 port, used for debug purposes (bootloader and operating system serial console).

UART3 UART2 is mapped to <code>/dev/ttymxc2ttymxc1</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

# connect the DB9 adapter bracket an UART transceiver (eg: TTL-232RGVIP-WE) to J35 and to the J22 connector on the SBCX boarda workstation# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)* leave J35.3 unconnected if the transceiver is self powered# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,18N1
