1. Board Support Package Mini Project – PCM-7230 TA: Shun-Lee Chang ( 張舜理 ) Important Dates: Borrowing PCM-7230: TODAY 15:00 ~ 18:00 Demo and your 2-page report: 4/14 (Tue) 15:00 ~ 18:00 TA Office: EECS ( 電資大樓 ) 701 E-mail: changsl@cs.nctu.edu.twchangsl@cs.nctu.edu.tw Contact: #54850 / 0919-972660

2. 2 Project Goals Learn how to assemble the PCM-7230 evaluation kit Learn how to install the boot loader Learn how to compile/install an embedded system

3. 3 Development Prerequisite OS –Windows XP Does Windows Vista work? –Linux 2.6 The project was verified on Fedora 10 The OS run upon VMWare shall be ok Hardware –Parallel port –COM port –D-sub (VGA) –USB slot

4. 4 2 Boxes PCM-7230 evaluation kit: 1 x PCM-7230 board 1 x CN8 cable (VGA) 1 x RST switch 1 x JTAG cable 1 x CN9-33 cable (COM1) 1 x Power switch cable (can be replaced by a jumper) 1 x Power-in cable 4 x Short rods 4 x Long rods 1 x CN9-47 cable (USB, optional) 1 x CN9-1 cable (Ethernet, optional) Other: 1 x Card reader 1 x 512MB CF card 1 x Power supply 1 x Power line Please return everything you get, including the boxes, in the end of this semester

5. 5 Assemble PCM-7230 Kit JTAG To Parallel To VGA reset Power inPower switch (jumper) To COM1 USB CF card slot rods

6. 6 White alignment line White notation

7. 7 The power switch cable is very fragile If broken –Solder it yourself –Use a jumper You must returned me the cable even it is broken

8. 8 Direction One PIN left JTAG

9. 9

10. 10 Files giveio.zip: JTAG driver Jen255.exe: JFlash, an application for writing bootloader into flash bootldr: (default) ARM Linux bootloader kernel: (default) ARM Linux kernel image ramdisk.gz: ARM Linux ramdisk arm_linux_gcc.tar.gz: Cross compiler linux.tgz: ARM Linux kernel source code i-boot-lite.tgz: bootloader source code

11. 11 Install Boot Loader Steps – install JTAG driver –Connect PCM-7230 and PC with the parallel port (JTAG cable) –Unzip giveio.zip, and read readme.txt if any trouble happens –Execute “LOADDRV.EXE” Fill the LoadDrv window with full path, including GIVEIO.SYS

12. 12 Install Boot Loader Steps – install boot loader –Power on PCM-7230 –Run “cmd” In the cmd window, Switch to the directory where giveio.cmd resides Execute “giveio” Switch to the directory where jen255.exe is Run “jen255.exe” to install a boot loader

13. 13 Before Booting PCM-7230 Configure 超級終端機

14. 14 Booting Copy the following files to CF card –kernel –ramdisk.gz Attach CF card with PCM-7230 Connect PCM-7230 and PC with the RS-232 (COM1) Run 超級終端機 Power on PCM-7230 –If everything is okay, you will see… –If you want to see 小企鵝, you need connect your PC and 7630 with the D-sub cable Default account/password is root/rootme

15. 15 Before Customization Install toolchain (on Linux 2.6) login as root mkdir /usr/local/arm cd /usr/local/arm tar xvfz somewhere/arm_linux_gcc.tar.gz export PATH=/usr/local/arm/2.95.3/bin:$PATH –Verify the correctness of your installation by executing arm-linux-gcc -v The directory contains arm_linux_gcc.tar.gz Unfortunately, the toolchain can be only installed here

16. 16 Build Boot Loader 需要 /usr/share/automake ，以 Fedora 10 為例 – 安裝 automake ( 使用 yum) –ln –s /usr/share/automake-1.7 /usr/share/automake 解壓縮 boot loader 原始碼，並編譯 boot loader –tar zxvf i-boot-lite.tgz –cd i-boot-lite make i-boot-lite/i-boot-cerf-board-pxa250_1.7-lite.img 為你的 boot loader ，請安裝到 PCM-7230 修改 boot loader: check src/main

17. 17 Demo 評分項目 1. 修改 Boot loader 的歡迎畫面，至少能顯 示你的學號

18. 18 Build Kernel Steps –tar zxf linux.tgz –cd linux/kernel –Run “make clean” and “make dep” to maintain the source (you only need to do it once) –Run “make menuconfig” to choose what driver you want (you can use default and skip this step) –Run “make zImage” to build your kernel –If everything is okay, the file “./arch/arm/boot/zImage” is your new kernel image (don’t forget to rename it to “kernel”)

19. 19 Customize ramdisk Steps –gzip -d ramdisk.gz –mkdir /mnt/ramdisk –mount -o loop -t ext2 ramdisk /mnt/ramdisk – 撰寫應用程式 app.c ，程式執行時顯示你的學號。 – 編譯 app.c arm-linux-gcc app.c -o app cp app /mnt/ramdisk/bin –umount /mnt/ramdisk –cat ramdisk | gzip -v9 > ramdisk.gz 將 ramdisk 掛載至 /mnt/ramdisk 目錄下 ramdisk 以含有 app 這隻程式 Your ramdisk

20. 20 Demo 評分項目 2. 能在 pcm-7230 上執行 app 3. 修改某個檔案，使得開機後，可以用超級終端機藉由 COM1 控制 pcm-7230 –Hint: google inittab ttyS0

21. 21 Demo Environment/Plan You MUST take your PCM-7230 –Customized boot loader must be already installed –Customized kernel/ramdisk are in the CF card Demo 1.Show boot loader’s welcome banner 2.Execute “app” 3.Show how to control the PCM-7230 via COM1 You can demo on your notebook/PC, or demo on the notebook I provide After demo, return me the 7230 kit including the 2 boxes
