• The U-Boot, busybox and Linux kernel build systems require that certain host packages be installed on the development host to function correctly. These packages are: make, gcc, perl and some others. Please refer to linux/Documentation/Changes for a list of host tools required to build the Linux kernel. The same set of tools is required for the U-Boot and busybox build.

• On the 64-bit Linux, install the following packages:

  • On the Ubuntu or Debian distribution:

  Code Block
  $ sudo dpkg --add-architecture i386 $ sudo apt-get update $ sudo apt-get install ia32-libs libc6-dev gcc-multilib

  • On the Fedora or CentOS distribution:

  Code Block
  $ sudo yum install glibc.i686

• The Linux Cortex-M GNU debugger (tools/bin/arm-buildroot-uclinuxfdpiceabi_sdk-buildroot/bin/arm-buildroot-uclinuxfdpiceabi-gdb) and the configuration scripts require that the following dynamically-linked libraries to be installed on the host:

  • libncurseslibz.so.1 (the zlib1g-dev package);

  • libtinfo.so.5 (the libncurses libtinfo5 package);

  • libexpat.so.1 (the expat package);

  • libpython2.7liblzma.so.5 (the liblzma5 package);

  • libgmp.so.1.010 (the libpython libgmp10 package);

  • For example, to be able to run arm-v7buildroot-linux-uclibceabiuclinuxfdpiceabi-gdb you'll have to do the following (once):

    • On Ubuntu-10.04 (x32):

    Code Block

    $ sudo vim /etc/apt/sources.list # Add the following lines to the begin of the file: deb http://ppa.launchpad.net/fkrull/deadsnakes/ubuntu lucid main deb-src http://ppa.launchpad.net/fkrull/deadsnakes/ubuntu lucid main $ sudo apt-key adv --keyserver http://keyserver.ubuntu.com \ --recv-keys DB82666C $ sudo apt-get update $ sudo apt-get install libncurses5 python2.7 python2.7-dev $ sudo ln -s /usr/lib/libncurses.so.5 /usr/lib/libtinfo.so.5

    • On CentOS 7 (x64):

    Code Block

    $ sudo yum install glibc.i686 ncurses-devel.i686 zlib.i686 \ expat-devel.i686 $ sudo yum install glibc-devel.i686 glibc-devel zlib-devel.i686 \ bzip2-devel.i686 openssl-devel.i686 ncurses-devel.i686 \ sqlite-devel.i686 readline-devel.i686tk-devel.i686 \ gdbm-devel.i686 db4-devel.i686 libX11-devel.i686 $ wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz $ unxz Python-2.7.12.tar.xz; tar xf Python-2.7.12.tar; \ cd Python-2.7.12 $ mkdir /opt/python-2.7.12.i686 $ BASECFLAGS=-m32 LDFLAGS=-m32 CFLAGS=-m32 ./configure \ --prefix=/usr --enable-shared $ make install altinstall

• The tools/bin/mkimage utility. It is expected that the utility will work as is on most of today's Linux distributions. If it fails to run on a certain host, you can build it for your specific Linux host from the sources included in the Linux Cortex-M distribution by running make tools from the top of the U-Boot tree.

• To build the run-time projects included to the distribution, you need to install the following host packages:

  • NFS server;

  • TFTP server;

  • Terminal emulator (picocom, minicom, kermit or PuTTY).

• If your target board uses USB for the serial console connection you might need to install the FTDI USB-UART driver fromhttp://www.ftdichip.com/Drivers/VCP.htm for your host.
