1 Embedded System Design Term Project Porting(v1.04) Jaeyong Chung SoC Laboratory Incheon National University

2 Porting The reason why you install an OS on your embedded system is not only to do multi-tasking Operating Systems provide hardware abstraction, which let you run many existing applications on your system These days, it is not common to build something from scratch Most software is developed by integrating existing programs/libraries There are tons of open-source programs on the Internet Porting is the process of adapting software so that an executable program can be created for a computing environment that is different from the one for which it was originally designed.

3 Open-source Community and many more Chung EPC6071 3

4 Term Project The objective is to port an open-source program for 320 embedded system Choose one out of 4 given programs (MP3 player, image viewer, web server, pacman game) Source codes will be provided Cross-compile and run it on the target system Chung EPC6071 4

5 Term Project You are supposed to change the USER INTERFACE of the programs You don t have to modify and even understand the core of the programs Modify the user interface and use as many I/O devices in the 320 (e.g., FND, dot-matrix, character display, keypad, etc) as possible Install necessary device drivers to the target system Driver sources and test programs will be given Chung EPC6071 5

6 General guidelines Download the source files Compile it for your intel PC Run it and think about how to modify its user interface Repeat when you don t have the board: Try to find how the program take inputs from the user and produce outputs in the source files Use printf here and there Compile it for your intel PC Run it Chung EPC6071 7

7 General guidelines Repeat until the project is done: Modify the source files referring to fnd_test.c, key_test.c, etc Cross-compile it for the 320 embedded system Transfer executables and libraries to the board using minicom Run it Chung EPC6071 8

8 Topics (easiest) HTTP server (tinyhttpd-0.1.0, ) (easy) MP3 Player (mpg , ) (moderate) Image Viewer (sxiv-1.2, ) (difficult) Pacman Game (njam-1.25, ) (difficult) Overlay System Use Xilinx Zynq SoC, 4 teams only Chung EPC6071 9
