<section end="History" /><section begin="Body" />

The GPIOs interface is available on the Evaluation Kit at the connector ''TBD:Jxxx''J8.

''Jxx'' J8 is a ''TBD:connector-type'' 20x2x2.54mm pin strip header connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).

UART3 is GPIOs are mapped to into banks each of which contains 32 pins. They are named as GPIO<codebank>/dev/ttymxc2_IO</codepin> device in Linux. The peripheral is used  Each pin can be addressed with an incremental number, calculated as the default serial console, both for the bootloader and the kernel.follows: GPIO = 32 x (<bank> - 1) + <pin>

To connect to Under Linux the debug serial port: # connect GPIOs can be manipulated su sysfs export or with 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,8,1gpio tools.
