This is the source distribution for RTEMS 4.8.1 source, add-ons,
and documentation. The primary development platforms supported are
GNU/Linux distribtions which use RPMs. MS-Windows is supported as a
The 4.8.1 release is the second release in the 4.8 series. In addition
to addressing problems in 4.8.0, it includes all bug fixes found in the
4.7 series along with a number of enhancements and bug fixes since the
4.7 release branch was made. Some of the enhancements included between
the 4.7 and 4.8 release series are listed at:
For Fedora users, loading the prebuilt tools should be very easy and
something like this:
(1) Load the appropriate Yum repository configuration
information. This example is for Fedora GNU/Linux.
RPMs are also provided for RedHat Enterprise Linux
# Replace NNN with your 1-8 to reflect the Fedora version
# Replace ARCH with your i386 or x86_64 to reflect your host architecture
rpm -ivh ftp://ftp.rtems.org/pub/rtems/linux/4.8/fedora/NNN/i386/rtems-4.8-yum-conf-0.10-1.fcNNN.noarch.rpm
(2) Load cross development RPMs for your RTEMS target architecture
along with the RTEMS 4.8 specific version of GNU autoconf
# Replace CPU with the name of the CPU architecture you
# want to use RTEMS on. Choice are:
# arm bfin h8300 i386 m68k mips powerpc sh sparc
yum -y install "*4.8*CPU*" "*4.8*auto*"
That's it. You should be able to configure and build RTEMS at this
point. If targeting a simulator BSP included with GDB (sparc/sis,
powerpc/psim, or mips/jm43904), you should be able to generate and run
target executables in a matter of minutes. Configuring qemu so that it
will boot an RTEMS application for the i386/pc386 takes a bit longer but
is still quite straightfoward. Normally it takes longer to download the
tools via ftp than to build RTEMS.
