The UARTs interface available on the Evaluation Kit at are mapped to the connector ''TBDfollowing connectors:Jxxx''.

''Jxx'' * J25 is a ''TBD:6x1x2.54 pitch vertical header for the UART4 port. This is a Digilent Pmod™ Compatible connectorfor the UART Pmod™ Compatiblemodule (6-type'' header Pin Pmod™ Compatible Connector Digilent Pmod™ Interface Specification Type 4 UART)* J21 is a standard DB9 male connector for the RS232 two-wires UART3 configurable UART5 port, used . The board provides some configuration options for debug purposes the selection of the UART mode (bootloader and operating system serial consoleRS232/RS422/RS485 with auto-direction).

The following table tables describes the interface signals: ==== UART4 ====

UART3 * UART4 is mapped to <code>/dev/ttymxc2ttymxc3</code> device in Linux. The peripheral * UART5 is used as the default serial console, both for the bootloader and the kernel.mapped to <code>/dev/ttymxc4</code> device in Linux

To connect to the debug serial port: # connect the DB9 * UART4 can be used with a PMOD adapter bracket to the J22 connector on the SBCX boardor with a TTL peripheral# connect * UART5 is a serial cable between DB9 connector and PC COM port through a NULL-modem cable MultiProtocol that support (not providedafter harware Jumper configuration)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200the RS232,N,8,1RS4222 or RS485 protocols. The related ''device tree file'' has to be properly configured too for enabling the GPIO transceiver configuration.
