UBC-220 User Manual 30
3.1 Introduction
UBC-220 platform is an embedded system with Linux kernel 3.0.35 inside. It contains
all system-required shell commands and drivers ready for UBC-220 platform. We do
not offer IDE development environment in UBC-220 BSP, users can evaluate and
develop under the Ubuntu 10.04LTS environment.
There are three major boot components for Linux, “u-boot.bin”, “uImage” and “File
System”. The “u-boot.bin” is for initializing peripheral hardware parameters; the “uIm-
age” is the Linux kernel image and the “File System” is for Linux O.S. used.
It will not be able to boot into the Linux environment successfully if one of above three
files is missing from the boot media (SD card, SATA HDD or onboard flash)
The purpose of this chapter is to introduce software development of UBC-220 to you,
so that you can develop your own application(s) efficiently.
UBC-220 is designed for Linux only. For now the official supported host version is
Ubuntu 10.04 LTS, hosting any other version may have compatibility issues. In this
case, we strongly recommend to have Ubuntu 10.04 LTS installed to your host PC
before start UBC-220 evaluation/development.
