Cross Development Environment: Dependency on Host Components
The cross development environment distribution has the following dependencies on Linux-host software components:
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 tolinux/Documentation/Change
s for a list of host tools required to build the Linux kernel. The same set of tools is required for the U-Boot andbusybox
build.On the 64-bit Linux, install the following packages:
On the Ubuntu or Debian distribution:
$ 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:
$ sudo yum install glibc.i686
The Linux Cortex-M GNU debugger (
tools/bin/arm-v7-linux-uclibceabi-gdb
) and the configuration scripts require that the following dynamically-linked libraries to be installed on the host:libncurses.so.5
(thelibncurses
package);libexpat.so.1
(theexpat
package);libpython2.7.so.1.0
(thelibpython
package);For example, to be able to run
arm-v7-linux-uclibceabi-gdb
you'll have to do the following (once):On Ubuntu-10.04 (x32):
$ 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):
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 fromVCP Drivers - FTDI for your host.
