This How-To is meant to be a starting point for people to learn use UART for IGEP devices as quickly and easily as possible. In this How-To, we use [http://labs.isee.biz/index.php/Pre-installed_software_on_IGEP_Processor_Boards IGEP Firmware] and a program that use UART peripherals. This How-To was tested in:
*[[IGEP firmware Yocto|IGEP firmware Yocto]] with and [[Linux_Kernel_2.6.37.y|Kernel 2.6.37.y]]with IGEPv2.
Example program has a debug option using GPIOs to debug via oscilloscope, this method is useful to learn about the Kernel latencies. Debug has set to "write" and "select" functions. [[Peripherals Summary#UART|More information]].
