Usually the following command sequence is used for SDK installing under Ubuntu 14:

1. sudo apt-get install ubuntu-minimal ubuntu-standard patch vim-common sed wget subversion git-core coreutils libbonobo2-common unzip texi2html texinfo libsdl1.2-dev docbook-utils gawk python-pysqlite2 diffstat make gcc build-essential xz-utils g++ desktop-file-utils chrpath libgl1-mesa-dev libglu1-mesa-dev autoconf automake groff libtool xterm libncurses5-dev cvs tofrodos

2. a) command: ls -l /bin/sh

                Message:  /bin/sh -> dash

1. b) command: sudo dpkg-reconfigure dash

                Answer after password – No

                Message:

                Removing 'diversion of /bin/sh to /bin/sh.distrib by dash'

                Adding 'diversion of /bin/sh to /bin/sh.distrib by bash'

                Removing 'diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz by dash'

                Adding 'diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz by bash'

1. c) command for checking: ls -l /bin/sh

                Message: /bin/sh -> bash

3. mount SDK 2.0 .iso file
4. cd <sdk-install-dir>.
5. ./sources/meta-freescale/scripts/host-prepare.sh

Usually Linux recommends also run the following command: sudo usr/sbin/visudo

6. . fsl-setup-env -m t2080rdb
7. bitbake fsl-image-minimal

This command sequence provides u-boot generation.

U-boot is boot loader. It contains start-up code.

Usually modification of u-boot configuration is enough for using a new board. Configuration of the u-boot is available in the following folder in u-boot source: /include/configs/.

See attached file.
