Hi,

1. I have described the usage and the current state of the BSP of the
new machine  mpc5125-twr in a tutorial and wanted to publish it on
gentoo-wiki.com. Unfortunately gentoo-wiki.com is currently  not accessible.

Here is the tutorial in text form.

2. I can provide it also as html file, if someone wants it.

3. I would like to publish this tutorial under
http://www.openembedded.org/index.php/Category:Machine
because I think this would be the right place for it.
How can I get write access to the openembedded-wiki?

Best regards

Jan

About this tutorial

   This tutorial describes all the steps which are needed to create the
linux
   kernel and different root file systems on a Gentoo Linux host for the
   board Freescale TWR-MPC5125 with Openembedded, a build framework for
   embedded Linux. The Linux Distribution Angstrom, which is part of
   Openembedded, is used here to create the linux kernel and to create
   several root file systems:

     o a minimal-image for testing purposes,

     o OPIE (Open Palmtop Integrated Environment), a graphical user
interface
       for PDAs,

     o GPE (GPE Palmtop Environment), a graphical user interface for
PDAs and

     o Xfce, a lightweight desktop environment.

   The minimal-image uses about 35MB RAM at runtime on the Freescale
   TWR-MPC5125. OPIE uses about 51MB RAM at runtime. GPE uses about 61MB RAM
   at runtime. Xfce uses about 95MB RAM at runtime.

   Note: This is the first release of a BSP for the board Freescale
   TWR-MPC5125 in Openembedded. It seems to work, but only few tests have
   been made so far.

Freescale TWR-MPC5125

   The Freescale TWR-MPC5125-KIT consists of one MPU module and a peripheral
   module which can be plugged between two backplane boards. On the MPU
   module is the Freescale MPC5125 with a Power Architecture e300c4 core.
   Freescale provides a Linux demo and the source code for the Linux kernel
   and for U-boot.

Folder Names

   These folders are used for

   Bitbake: $MY_BITBAKE

   Openembedded: $MY_OPENEMBEDDED

   Project configuration: $MY_PROJECT

   Build: $MY_TMP

   NFSRoot: $MY_NFSROOT

   Source: $MY_SRC

   The application bitbake is installed into the folder $MY_BITBAKE.

   The project definitions of openembedded are installed into the folder
   $MY_OPENEMBEDDED.

   Source files are downloaded by bitbake into the folder $MY_SRC.

   The configuration files for the current project are created in the folder
   $MY_PROJECT.

   bitbake creates all files in the folder $MY_TMP.

   The created root file systems are extracted in the folder $MY_NFSROOT and
   can be mounted by the target via NFS.

   The current project is just called test01.

   Define environment variables:

 export MY_BITBAKE=/MyOE/bitbake-1.12;
 export MY_OPENEMBEDDED=/MyOE/openembedded;
 export MY_PROJECT=/MyOE/project/test01;
 export MY_TMP=/MyOE/tmp/test01;
 export MY_NFSROOT=/MyOE/nfsroot/test01;
 export MY_SRC=/usr/portage/distfiles;

Install Software for Openembedded

   Before you can install and use openembedded, you need to install some
   software. At first set the use flags.

 nano /etc/portage/package.use/openembedded-use

   New or changed content of file openembedded-use:

 # use flags for openembedded
 dev-util/quilt graphviz

   Emerge the software, which is missing.

 emerge --update --ask -v psyco patch make sed dev-lang/python m4 bison
cvs openjade \
 quilt sgmltools-lite docbook-xml-dtd docbook-dsssl-stylesheets xmlto
docbook-sgml-utils \
 libpcre boost subversion texi2html pysqlite chrpath diffstat

   It is possible that portage requests that some other use flags are set
   too. psyco is not available for gentoo amd64 i.e. x86_64.

   Now you can check, if all needed applications exist

 which libtool python2.6 git svn cvs make gcc g++ patch help2man
diffstat texi2html \
 bzip2 gawk tar md5sum texi2pdf chrpath

   texi2pdf is part of the package texinfo.

Install Bitbake

   Create folders and download the branch 1.12 of bitbake:

 mkdir -p $MY_BITBAKE;
 git clone -b 1.12 git://git.openembedded.net/bitbake $MY_BITBAKE

   The size of this folder is about 3MB.

Install Openembedded

   Create folders and download the branch master of openembedded:

 git clone git://git.openembedded.net/openembedded $MY_OPENEMBEDDED

   The size of this folder is about 150MB.

Update

   From time to time you need to update your local versions of openembedded
   and bitbake.

   Update Openembedded

 cd $MY_OPENEMBEDDED;
 git pull --rebase

   Update Bitbake

 cd $MY_BITBAKE;
 git pull --rebase

Install the Patch for the Board Freescale TWR-MPC5125

   Because Openembedded has so far no configuration files for the board
   Freescale TWR-MPC5125, some patches need to be applied.

   Note: The patches will be soon released and the URL announced.

   When the patches are published on the Openembedded patch list
   http://patches.openembedded.org/project/oe/list they can be easily
   applied:

 more $MY_OPENEMBEDDED/contrib/patchwork/pw-am.sh
 cd $MY_OPENEMBEDDED;
 $MY_OPENEMBEDDED/contrib/patchwork/pw-am.sh  xxx yyy

Create the configuration file

   For each project you should create a project folder with a configuration
   file. Here it is $MY_PROJECT. Almost all settings for your project are
   defined in the local.conf file. At first use the file
local.conf.sample as
   template for the local.conf file.

 mkdir -p $MY_PROJECT/conf;
 cp $MY_OPENEMBEDDED/conf/local.conf.sample $MY_PROJECT/conf/local.conf

   Then adjust the configuration file

 nano $MY_PROJECT/conf/local.conf

   New or changed content of file local.conf:

 # DL_DIR = "${HOME}/sources"
 # use the distfiles of gentoo
 DL_DIR = "/usr/portage/distfiles"

   Bitbake downloads source files into and creates md5 files in the folder
   which is specified by the environment variable DL_DIR. Portage and
bitbake
   download the same source files. You can define DL_DIR to point to the
   source file repository of portage which is by default
   /usr/portage/distfiles. This avoids downloading a file two times by
   portage and bitbake. Make sure that you have access permissions to this
   folder. If you don't want to use the same download folder, then choose
   some other folder name for DL_DIR.

   Note: I don't know if sharing the download folder is a real feature of
   portage and openembedded, but it works for me. Sometimes when a fetch
   fails, I use Workaround_when_fetch_fails

   Continue adjusting the local.conf file. New or changed content of file
   local.conf:

 # BBFILES := "${@bb.fatal('Edit your conf/local.conf: BBFILES')}"
 BBFILES = "/MyOE/openembedded/recipes/*/*.bb"

 # on gentoo help2man unknown arg --no-discard-stderr
 # ASSUME_PROVIDED += "help2man-native"

 # TMPDIR = /usr/local/projects/oetmp
 TMPDIR = /MyOE/tmp/test01
 # TMPDIR is created by bitbake

 # GLIBC_GENERATE_LOCALES = "en_US.UTF-8 en_GB.UTF-8 de_DE.UTF-8"
 GLIBC_GENERATE_LOCALES = "en_US.UTF-8"

 #IMAGE_FSTYPES = "jffs2 tar"
 IMAGE_FSTYPES = "jffs2 tar"

 # PARALLEL_MAKE = "-j 4"
 PARALLEL_MAKE = "-j 4"

 # BB_NUMBER_THREADS = "2"
 BB_NUMBER_THREADS = "2"

   Delete the last line of the file, otherwise you will get an error
message.
   The value of the variable DISTRO is the name of a distribution. The
   allowed values are the file names without suffix in the folder
   $MY_OPENEMBEDDED/conf/distro.

 ls $MY_OPENEMBEDDED/conf/distro

   The value of the variable MACHINE is the name of a target board or target
   system. The allowed values are the file names without suffix in the
folder
   $MY_OPENEMBEDDED/conf/machine.

 ls $MY_OPENEMBEDDED/conf/machine

   Define distribution and machine. Here mpc5125-twr.conf fits best to
   Freescale TWR-MPC5125.New or changed content of file local.conf:

 DISTRO="angstrom"
 MACHINE="mpc5125-twr"

   Clean work folder after succesfully building.New or changed content of
   file local.conf:

 INHERIT += "rm_work"

Environment setup

   Before you can call bitbake, you need to setup the environment. Because
   each project can have its own environment, you should create a script in
   the project folder.

   nano $MY_PROJECT/setup-env

   New or changed content of file setup-env:

 export PATH="/MyOE/bitbake-1.12/bin:${PATH}"
 export BBPATH="/MyOE/project/test01:/MyOE/openembedded/"

 # you can set also here: BB_ENV_EXTRAWHITE

 # set a new prompt
 export PS1="test01 $PS1"

 echo "Configure Openembedded for test01 "

   Call the script file setup-env only once, before you start using bitbake.
   The prompt will indicate, if you have called it or not.

   All the settings in setup-env and local.conf are independent of the
   environment variables MY_OPENEMBEDDED, MY_BITBAKE, MY_SRC, MY_NFSROOT,
   MY_PROJECT. You don't need them to run bitbake.

Image minimal-image

  Build Image

   You can be in any folder you like. You should be logged in as a common
   user. You don't need root privileges most of the time. Start building an
   image

 source $MY_PROJECT/setup-env;
 bitbake minimal-image

   Output:

 Build Configuration:
 BB_VERSION        = "1.12.0"
 METADATA_BRANCH   = "master"
 METADATA_REVISION = "6b9a381"
 TARGET_ARCH       = "ppc"
 TARGET_OS         = "linux"
 MACHINE           = "mpc5125-twr"
 DISTRO            = "angstrom"
 DISTRO_VERSION    = "v20110406"


   At first all cross-tools (called native in openembedded), e.g. the
   cross-compiler are build and installed in the folder $MY_TMP. Then the
   cross-tools are used to build all needed software packages. Root file
   images and the kernel images can be found in the folder
   $MY_TMP/deploy/eglibc/images/mpc5125-twr/

 ls  -1s $MY_TMP/deploy/eglibc/images/mpc5125-twr/

   These are the files which are created: Output:

  Linux Kernel

   The board is already shipped with a Linux kernel in flash. U-boot can
load
   the kernel from a TFTP server or from flash. Here we load the kernel from
   a TFTP server.

 cp
$MY_TMP/deploy/eglibc/images/mpc5125-twr/uImage-2.6.29-r11-mpc5125-twr.bin
/tftpboot/uImage-mpc5125-twr;
 cp
$MY_TMP/deploy/eglibc/images/mpc5125-twr/uImage-2.6.29-r11-mpc5125-twr.dtb
 /tftpboot/uImage-mpc5125-twr-dtb;

  Create the Root File System

   Take the rootfs image and extract it into another folder. The extraction
   needs to be done with root privileges.

 mkdir -p $MY_NFSROOT/mpc5125-twr-minimal-image;
 cd  $MY_NFSROOT/mpc5125-twr-minimal-image;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/minimalist-image-mpc5125-twr.tar.gz

   Extract the kernel modules into the root file system.

 cd  $MY_NFSROOT/mpc5125-twr-minimal-image;
 tar tzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;
 sudo rm -rf lib/modules/2.6.29.1;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;

   The rootfs can be now mounted via NFS.

  nfs server

   Configure the nfs server to export the rootfs

 nano /etc/exports

   New or changed content of file /etc/exports:

 /MyOE/nfsroot/test01/mpc5125-twr-minimal-image
192.168.1.255/24(rw,no_root_squash,async,subtree_check)

 exportfs -r

  Prepare the Board

   You need a monitor, a USB mouse, a USB keyboard and a USB Hub. Only the
   TWR-MPC5125 MPU module is used.

     o Connect the monitor to the HDMI port of the TWR-MPC5125 MPU module.
       E.g. you can use a HDMI to DVI-D cable. The resolution has been
       640x480 60Hz during the tests.

     o Connect the mouse and the keyboard to a USB hub. Connect the USB hub
       to the Mini-AB connector on the board which is next to the HDMI
       connector. Use the Mini-B to receptable A cable.

     o Connect a USB cable to your host computer and to the Mini-B connector
       next to the SDHC card slot. This is the Serial-to-USB bridge.

     o Connect an Ethernet cable to the board.

     o Connect a 5V power supply to the board, if it is not already provided
       by the USB cable to your host computer.

  Serial Port

   There is a Serial-to-USB bridge on the board, which connects the serial
   port PSC0 to a USB port. When the Mini-B connector next to the SDHC card
   slot on the board is connected to a USB port of the host, then this
   message appears in /var/log/messages:Output:

 usb 1-1.2: new full speed USB device using ehci_hcd and address 5
 cdc_acm 1-1.2:1.0: This device cannot do calls on its own. It is not a
modem.
 cdc_acm 1-1.2:1.0: ttyACM0: USB ACM device
 usbcore: registered new interface driver cdc_acm
 cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and
ISDN adapters

   Install the terminal application cu on your host system.

 emerge -av taylor-uucp

   Now open a terminal to the board

 cu -l /dev/ttyACM0

  U-boot

   Use the Serial-to-USB bridge to connect to the serial port PSC0 of the
   CPU. Boot the board and enter the command line of u-boot. Define the IP
   address of the board, the IP address of the server and the path for
   nfsroot. Check the current settings of the variables which are used to
   boot the board.

 echo ipaddr=$ipaddr;
 echo gatewayip=$gatewayip;
 echo netmask=$netmask;
 echo serverip=$serverip;
 echo kernel_loader=$kernel_loader_addr;
 echo fdt_loader_addr=$fdt_loader_addr;
 echo rootpath=$rootpath;
 echo consoledev=$consoledev;
 echo baudrate=$baudrate;
 echo hostname=$hostname;
 echo netdev=$netdev;
 echo bootargs=$bootargs;
 echo bootcmd=$bootcmd;
 echo tftpboot=$tftpboot;

   Change the variables which are used to boot the board.

 setenv ipaddr 192.168.1.8;
 setenv gatewayip 192.168.1.1;
 setenv netmask 255.255.255.0;
 setenv serverip 192.168.1.33;
 setenv consoledev ttyPSC0;
 setenv netdev eth0;

   Define the command to load the kernel from a TFTP server.

 set tftpboot 'tftp $kernel_loader_addr uImage-mpc5125-twr; tftp
$fdt_loader_addr uImage-mpc5125-twr-dtb; bootm $kernel_loader_addr -
$fdt_loader_addr '

   Define the nfsroot path and the bootcmd argument. When you want to use a
   different nfsroot, you need to change only rootpath and bootargs.

 setenv rootpath /MyOE/nfsroot/test01/mpc5125-twr-minimal-image;
 setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath}
console=${consoledev},${baudrate}
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
panic=1;

   Save the new environment and boot again.

 saveenv
 run tftpboot

  Status

   The image seems to work with one exception. Unfortunately getty reports a
   Segmentation fault, when started. Therefore login via the devices
   /dev/tty1 or /dev/ttyPSC0 is not possible. You can login to the board
only
   with ssh via Ethernet.

 ssh root at 192.168.1.8

   No password is needed.

    Problem with getty

   When getty is called in /etc/inittab, it is respawned. You can test it on
   the command line:

 getty 115200 /dev/tty1

   Output:

 Segmentation fault

   Output on the display consoleOutput:

 getty:ioctl() TIOCSPGRP call failed: Inappropriate ioctl for device

   For the device /dev/ttyPSC0 a segmentation fault occurs too.

 getty 115200 /dev/tty1

   Output:

 Segmentation fault

Image opie-image

   Only the differences to Image_minimal-image are described.

  Build Image opie-image

   You can be in any folder you like. You should be logged in as a common
   user.Call the script setup-env only once.

 source $MY_PROJECT/setup-env

   Start building the image.

 bitbake opie-image

   Root file images and the kernel images can be found in the folder
   $MY_TMP/deploy/eglibc/images/mpc5125-twr/

 ls  -1s $MY_TMP/deploy/eglibc/images/mpc5125-twr/

  Create the Root File System

   Take the rootfs image and extract it into another folder. The extraction
   needs to be done with root privileges.

 mkdir -p $MY_NFSROOT/mpc5125-twr-opie-image;
 cd  $MY_NFSROOT/mpc5125-twr-opie-image;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/opie-image-mpc5125-twr.tar.gz

   Extract the kernel modules into the root file system.

 cd  $MY_NFSROOT/mpc5125-twr-opie-image;
 tar tzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;
 sudo rm -rf lib/modules/2.6.29.1;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;

   The rootfs can be now mounted via nfs.

  NFS Server

   Configure the NFS server to export the rootfs

 nano /etc/exports

   New or changed content of file /etc/exports:

 /MyOE/nfsroot/test01/mpc5125-twr-opie-image
192.168.1.255/24(rw,no_root_squash,async,subtree_check)

 exportfs -r

  U-boot

   Change the path of the root file system and the bootargs.

 setenv rootpath /MyOE/nfsroot/test01/mpc5125-twr-opie-image;
 setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath}
console=${consoledev},${baudrate}
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
panic=1

   Save the new environment and boot the board again.

 saveenv
 run tftpboot

   In the GUI you can select Application -> Systeminfo -> Benchmark and run
   some benchmarks. Here are the results:Output:

 Integer Arithmetic 1161170 dhrys
 Floating Point Unit 0.09 secs

 Gfx Rendering 3324.75.00gops/sec
 RAM Performance 62.00 MB/s; 44.64 MB/s

  Status

   The GUI of OPIE appears on the screen and can be controlled by the mouse
   and the keyboard. A small black rectangle appears in the upper left
   corner. Several errors like missing group names are reported, when
   booting, but the GUI appears and can be used. This is just a starting
   point for using OPIE. Unfortunately getty reports a Segmentation fault,
   when started. Therefore login via the devices /dev/ttyPSC0 or
/dev/tty1 is
   not possible.

  Screenshots

   A screenshot can be found at
   http://en.wikipedia.org/wiki/OPIE_user_interface.

Image x11-gpe-image

   Only the differences to Image_minimal-image are described.

  Build Image x11-gpe-image

   You can be in any folder you like. You should be logged in as a common
   user.Call the script setup-env only once.

 source $MY_PROJECT/setup-env

   Start building the image.

 bitbake x11-gpe-image

   Root file images and the kernel images can be found in the folder
   $MY_TMP/deploy/eglibc/images/mpc5125-twr/

 ls  -1s $MY_TMP/deploy/eglibc/images/mpc5125-twr/

  Create the Root File System

   Take the rootfs image and extract it into another folder. The extraction
   needs to be done with root privileges.

 mkdir -p $MY_NFSROOT/mpc5125-twr-x11-gpe-image;
 cd  $MY_NFSROOT/mpc5125-twr-x11-gpe-image;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/x11-gpe-image-mpc5125-twr.tar.gz

   Extract the kernel modules into the root file system.

 cd  $MY_NFSROOT/mpc5125-twr-x11-gpe-image;
 tar tzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;
 sudo rm -rf lib/modules/2.6.29.1;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;

   The rootfs can be now mounted via nfs.

  NFS Server

   Configure the NFS server to export the rootfs

 nano /etc/exports

   New or changed content of file /etc/exports:

 /MyOE/nfsroot/test01/mpc5125-twr-x11-gpe-image
192.168.1.255/24(rw,no_root_squash,async,subtree_check)

 exportfs -r

  U-boot

   Change the path of the root file system and the bootargs.

 setenv rootpath /MyOE/nfsroot/test01/mpc5125-twr-x11-gpe-image;
 setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath}
console=${consoledev},${baudrate}
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
panic=1

   Save the new environment and boot the board again.

 saveenv
 run tftpboot

  Status

   The GUI of GPE appears on the screen and can be controlled by the mouse
   and keyboard. A small black rectangle appears in the upper left corner of
   the display. Several errors like missing group names are reported, when
   booting, but the GUI appears and can be used. This is just a starting
   point for using GPE. Unfortunately getty reports a Segmentation fault,
   when started. Therefore login via the devices /dev/ttyPSC0 or
/dev/tty1 is
   not possible. You can login to the board with ssh via Ethernet.

  Screenshots

   Screenshots can be found here

Image xfce46-image

   Only the differences to Image_minimal-image are described.

  Build Image xfce46-image

   You can be in any folder you like. You should be logged in as a common
   user.Call the script setup-env only once.

 source $MY_PROJECT/setup-env

   Start building the image.

 bitbake xfce46-image

   Root file images and the kernel images can be found in the folder
   $MY_TMP/deploy/eglibc/images/mpc5125-twr/

 ls  -1s $MY_TMP/deploy/eglibc/images/mpc5125-twr/

  Create the Root File System

   Take the rootfs image and extract it into another folder. The extraction
   needs to be done with root privileges.

 mkdir -p $MY_NFSROOT/mpc5125-twr-xfce46-image;
 cd  $MY_NFSROOT/mpc5125-twr-xfce46-image;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/xfce46-image-mpc5125-twr.tar.gz

   Extract the kernel modules into the root file system.

 cd  $MY_NFSROOT/mpc5125-twr-xfce46-image;
 tar tzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;
 sudo rm -rf lib/modules/2.6.29.1;
 sudo tar xzf
$MY_TMP/deploy/eglibc/images/mpc5125-twr/modules-2.6.29-r11-mpc5125-twr.tgz;

   The rootfs can be now mounted via nfs.

  NFS Server

   Configure the NFS server to export the rootfs

 nano /etc/exports

   New or changed content of file /etc/exports:

 /MyOE/nfsroot/test01/mpc5125-twr-xfce46-image
192.168.1.255/24(rw,no_root_squash,async,subtree_check)

 exportfs -r

  U-boot

   Change the path of the root file system and the bootargs.

 setenv rootpath /MyOE/nfsroot/test01/mpc5125-twr-xfce46-image;
 setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath}
console=${consoledev},${baudrate}
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
panic=1

   Save the new environment and boot the board again.

 saveenv
 run tftpboot

  Start Xfce

   Login as root, check the current settings of the nameserver and adjust
   them, if needed.

 cat /etc/resolv.conf
 echo "nameserver 192.168.1.1" >/etc/resolv.conf

   Start the GUI.

 startxfce4 &

  Status

   The GUI of Xfce appears on the screen and can be controlled by the mouse
   and keyboard. A small black rectangle appears in the upper left corner of
   the display. Several errors like missing group names are reported, when
   booting, but the GUI appears and can be used. X server reports serveral
   warnings but works. This is just a starting point for using xfce.
   Unfortunately getty reports a Segmentation fault, when started. Therefore
   login via the devices /dev/ttyPSC0 or /dev/tty1 is not possible. You can
   login to the board with ssh via Ethernet.

Troubleshooting

  Workaround when fetch fails

   When you use the portage distfiles folder for downloads and bitbake fails
   while fetching even when the file is there, this has helped usually:

 sudo chmod -R g+w /usr/portage/distfiles

   Start bitbake again.

  Workaround for cannot stat error

   When you start bitbake the current date is saved in some folder names.
   When bitbake fails and you restart it on another day, the the folder
names
   are different. You need to copy the files from the old folder to the new
   folder like in this example and then start bitbake again: Output:

 install: cannot stat
`/MyOE/tmp/test01/work/mpc5125-twr-angstrom-linux/angstrom-version-1_v20110406-r6/lsb_release':
No such file or directory
 NOTE: package angstrom-version-1_v20110406-r6: task do_install: Failed

 cd /MyOE/tmp/test01/work/mpc5125-twr-angstrom-linux;
 cp angstrom-version-1_v20110406-r6/lsb_release
angstrom-version-1_v20110406-r6/

  Bitbake Reports an Error

   You are using the master branch of openembedded, which is constantly
   changing. This is the latest version of openembedded. If the latest
   version cannot be build, you can try to use the latest tested version.
   Currently this is the version with the tag
   021312cbea3bd07f2ec8591d667998c9c7b28b3a.

 git status

   Save all your changes, which you don't want to lose, before you continue.
   Change to the tag 021312cbea3bd07f2ec8591d667998c9c7b28b3a.

 git reflog;
 git tag;
 git reset 021312cbea3bd07f2ec8591d667998c9c7b28b3a;

   Save and remove tracked files.

 git stash save

   Delete untracked files and directories dry-run

 git clean -fdn

   Delete untracked files and directories

 git clean -fd

   Check the current status.

 git status;
 git reflog;

   Now install the patches for mpc5125-twr and try to build the images in an
   empty directory $MY_TMP again.
