Overview

To avoid problems with repeatability and deployments this page hosts the default images to be used for the various projects. If you make modifications to your image you should create new patches, update .tgz files, etc. rather than simply creating new images so we have a way of getting from one image to another. For example, 'take the current image, run this patch on it, and copy these files to it'.

Current Image

The recommended system image:

Other Image Builds

February 27, 2007

Built using the following two scripts build command and build helper script.

• Filesystem was changed to support multiroute wifi units (a new fs.jffs2 image was created)
• Changes disable www access via the usb gadget (under linux only because network bridges don't appear to work in Windows)
  • removed "gateway 192.168.99.100" from /etc/network/interfaces

January 26, 2007

Built using the following two scripts build command and build helper script.

• Changed Zydas driver to build for revB boards
• Added lib bluetooth

January 24, 2007

Built using the following two scripts build command and build helper script.

• Gadget driver only affects the zImage
• console/no console affects all 3 files

Description	Bootloader	Kernel Image	Filesystem
Console on STD UART Windows Ethernet Gadget	blob	zImage	fs.jffs2
Console on STD UART Unix Ethernet Gadget	blob	zImage	fs.jffs2
No console on STD UART Windows Ethernet Gadget	blob	zImage	fs.jffs2
No console on STD UART Unix Ethernet Gadget	blob	zImage	fs.jffs2

Comparing two filesystem images

To compare two, fs.jffs2, file system images you can simply mount both images on a machine and do a diff on them: <bash>mkdir /mnt/jffs2ImageA mkdir /mnt/jffs2ImageB mknod /dev/mtdblock0 b 31 0 mknod /dev/mtdblock1 b 31 1

echo "Change fs.jffs2 to point to your images" losetup /dev/loop0 fs.jffs2_A losetup /dev/loop1 fs.jffs2_B

modprobe blkmtd device=/dev/loop0,/dev/loop1 mount -t jffs2 /dev/mtdblock0 /mnt/jffs2ImageA mount -t jffs2 /dev/mtdblock1 /mnt/jffs2ImageB

diff -urN /mnt/jffs2ImageA /mnt/jffs2ImageB</bash>

To remove the mounted images: <bash>sync umount /dev/mtdblock0 umount /dev/mtdblock1 modprobe -r blkmtd losetup -d /dev/loop0 losetup -d /dev/loop1</bash>

Script to update new images

<bash>mkdir -p /var/www/files/imote2/images/backup_2_6_2007/Console_nixGadget/ mkdir -p /var/www/files/imote2/images/backup_2_6_2007/Console_winGadget/ mkdir -p /var/www/files/imote2/images/backup_2_6_2007/noConsole_nixGadget/ mkdir -p /var/www/files/imote2/images/backup_2_6_2007/noConsole_winGadget/ cp -a /projects/builds/buildDir/Console_nixGadget/images /var/www/files/imote2/images/backup_2_6_2007/Console_nixGadget/ cp -a /projects/builds/buildDir/Console_winGadget/images /var/www/files/imote2/images/backup_2_6_2007/Console_winGadget/ cp -a /projects/builds/buildDir/noConsole_nixGadget/images /var/www/files/imote2/images/backup_2_6_2007/noConsole_nixGadget/ cp -a /projects/builds/buildDir/noConsole_winGadget/images /var/www/files/imote2/images/backup_2_6_2007/noConsole_winGadget/ cp -a /var/www/files/imote2/patches /var/www/files/imote2/images/backup_2_6_2007/ cp /projects/builds/build /var/www/files/imote2/images/backup_2_6_2007/ cp /projects/builds/buildScript /var/www/files/imote2/images/backup_2_6_2007/ cd /var/www/files/imote2/images/current rm ./blob rm ./fs.jffs2 rm ./zImage ln -s ../backup_2_6_2007/Console_winGadget/images/blob ./blob ln -s ../backup_2_6_2007/Console_winGadget/images/fs.jffs2 ./fs.jffs2 ln -s ../backup_2_6_2007/Console_winGadget/images/zImage ./zImage cd /var/www/files/imote2/images/current/backup_2_6_2007/ find ./ -type f -exec chmod 444 {} \; find ./ -type d -exec chmod 755 {} \; </bash>
