This How-To is meant to be a starting point for people to learn use UART for IGEP v2 devices as quickly and easily as possible. In this how-to, we use a program'''(upload source code)''', executed twice in separated progres at the same IGEP:. Its functions function is get a number from UART, increase it and send result via other UART, the result will be a infinite loop between 2 UARTs. This program was tested in [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]].
