This How-To is meant to be a starting point for people to learn use UART for IGEPv2 devices as quickly and easily as possible. In this how-to, we use [http://releases.linaro.org/platform/linaro-m/headless/final/linaro-m-headless-tar-20101108-2.tar.gz Linaro Headless] with [[Linux Kernel 2.6.35.y|Kernel 2.6.35.y]] and [http://labs.isee.biz/images/e/eeindex.php/UartPre-test-beta2.tarinstalled_software_on_IGEP_Processor_Boards IGEP Firmware].bz2 UART test program] More information about [http://en.wikipedia.org/wiki/UART UART].
'''Note''': This program has a debug option using GPIOs to debug via oscilloscope, this option is useful to learnt about the Kernel latencies. Debug has set to "write" and "select" functions.
