This document describes how to create a MeeGo image for the TI OMAP4 Blaze development board.

Contents

Prerequisites

  • Sourcery G++ Lite 2009q1 
wget -c http://www.codesourcery.com/sgpp/lite/arm/portal/package4571/public/arm-none-linux-gnueabi/arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
mkdir -p ${HOME}/opt
tar -C ${HOME}/opt -jxf arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
  • MIC2

Reference http://wiki.meego.com/Image_Creation to set up MIC2

  • Environment Variables 
PATH=${HOME}/opt/arm-2009q1/bin:${PATH}
export BLAZESOURCE=${HOME}/blaze.source
export BLAZEFS=${HOME}/meego-blaze-rootfs
  • Create ${BLAZESOURCE} 
mkdir -p ${BLAZESOURCE}

Get Files

  • u-boot 
cd ${BLAZESOURCE}
git clone git://git.omapzoom.org/repo/u-boot.git
cd ${BLAZESOURCE}/u-boot
git checkout --track -b omap4_dev origin/omap4_dev

git clone git://dev.omapzoom.org/pub/scm/integration/kernel-omap4.git
cd ${BLAZESOURCE}/kernel-omap4
git checkout --track -b L24.9 origin/L24.9
  • OMAP44xx SGX SDK

TI have not yet released OMAP44xx SGX SDK publicly. 

cd ${BLAZESOURCE}
wget -c http://wiki.meego.com/images/00-device-omapfb.conf

wget -c http://wiki.meego.com/images/Blaze.sh

Build

  • u-boot 
cd ${BLAZESOURCE}/u-boot

make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm uImage
make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm modules
  • MeeGo rootfs 
cd ${BLAZESOURCE}
./Blaze.sh

Make Bootable SD Card

  • Format SD

Reference http://www.omappedia.org/wiki/SD_Configuration to format SD card. Insert formated bootable SD card, /media/boot & /media/rootfs should be mounted automatically.

  • Install binaries to ${BLASEFS} 
# kernel modules
(cd ${BLAZESOURCE}/kernel-omap4 ; sudo PATH=${PATH} make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm INSTALL_MOD_PATH=${BLAZEFS} modules_install)
# 00-device-omapfb.conf
sudo cp ${BLAZESOURCE}/00-device-omapfb.conf ${BLAZEFS}/etc/X11/xorg.conf.d
# OMAP44xx SGX SDK
# TI have not yet released OMAP44xx SGX SDK publicly.
  • Install binaries to SD 
cp ${BLAZESOURCE}/x-loader/MLO /media/boot
cp ${BLAZESOURCE}/u-boot/u-boot.bin /media/boot
cp ${BLAZESOURCE}/kernel-omap4/arch/arm/boot/uImage /media/boot
sudo cp -rfp ${BLAZEFS}/* /media/rootfs

Make Blaze eMMC Bootable

  • Boot from SD Card
  • Login from serial console and insert g_file_storage module 
MeeGo release 1.0.90 (MeeGo)
Kernel 2.6.35 on an armv7l

Last login: Sat Jan  1 08:03:40 on ttyO2
[root@localhost ~]# modprobe g_file_storage file=/dev/mmcblk0 stall=0 removable=1
  • Connect the Blaze micro USB connector to your Linux box. You should be able to access Blaze eMMC as normal storage device.

  • Format Blaze eMMC

Reference http://www.omappedia.org/wiki/SD_Configuration to format Blaze eMMC. Disconnect the Blaze micro USB connector and connect again, /media/boot & /media/rootfs should be mounted automatically.

  • Install binaries to Blaze eMMC

Please change /dev/sdb to your real device name. 

sudo dd if=${BLAZESOURCE}/x-loader/MLO of=/dev/sdb bs=1024 seek=128
sudo dd if=${BLAZESOURCE}/u-boot/u-boot.bin of=/dev/sdb bs=1024 seek=512
cp ${BLAZESOURCE}/kernel-omap4/arch/arm/boot/uImage /media/boot
sudo cp -rfp ${BLAZEFS}/* /media/rootfs
  • Change Blaze sysboot selection S2-(6:1) from default 0b000101 to 0b000000, ie S2-(6:1) is (on, on, on, on, on, on).
  • Remove SD card, reboot from Blaze eMMC, modify u-boot parameters
