eCos - the Embedded Configurable Operating System - release 3.0 README ====================================================================== March 2009 Welcome to the eCos 3.0 public release. This README contains a list of known problems with the eCos 3.0 release. Please check for further issues by searching the Bugzilla database for product "eCos" version "3.0": http://bugs.ecos.sourceware.org/query.cgi If you discover new bugs with this release please report them using Bugzilla: http://bugs.ecos.sourceware.org/enter_bug.cgi ------------------------------------------------------------------------------ System Requirements ------------------- This release has been tested against Microsoft Windows 2000, Windows XP, Windows Vista and multiple x86 Linux distributions. Microsoft Windows 95, Windows *** and Windows ME are not supported. The Linux-hosted eCos development tools require libstdc++ v3 (/usr/lib/libstdc++.so.5). Users of Linux distributions which provide a more recent libstdc++ may need to install a libstdc++ v3 compatibility package. Installation of the compatibility package may be achieved as follows: Fedora: yum install compat-libstdc++-33 openSUSE: zypper install compat-libstdc++ Ubuntu: apt-get install libstdc++5 The Linux-hosted eCos Configuration Tool also requires the GTK+ toolkit version 2.0 or later. The Microsoft Windows-hosted eCos development tools require a recent installation of the Cygwin compatibility layer and associated command-line tools. The Cygwin setup program (installer) may be downloaded at: http://www.cygwin.com An installation of these tools dating from September 2008 or later is recommended. In addition to the packages provided within the "Base" category of the Cygwin installer, the following packages must be installed for correct operation of the eCos installer, eCos host tools, GNU compilation tools and eCos build system: gcc libmpfr1 libpng12 make patch tcltk sharutils wget ------------------------------------------------------------------------------ eCos 3.0 Errata --------------- * Compilation of eCos has been tested for those targets which use the following GNU toolchains: arm-eabi arm-elf i386-elf mipsisa32-elf m68k-elf powerpc-eabi sh-elf Compilation of eCos for targets using other toolchains is untested and may not work correctly. * The pre-built arm-eabi toolchain does not support ARM7DI and StrongARM processors. When building eCos for such targets, developers are advised to use the older arm-elf toolchain based on GCC 3.2.1. * Occasional internal compiler errors have been observed when building eCos and tests with the prebuilt m68k-elf toolchain. Such errors are highly sensitive to any changes in the source code. In many cases, the compiler optimisation level may be reduced as a workaround. However, note that building the kernel file clock.cxx without optimisation when configured with CYGDBG_USE_ASSERTS will also trigger an internal compiler error. In such cases, removal of the the compiler flag '-fomit-frame-pointer' may serve as a workaround. * The cxxsupp test fails for target 'linux' (the synthetic target) on certain recent Linux distributions (eg Fedora 10). This failure arises when libgcc assumes that glibc has initialised the GS register to reference per-thread data. * Compilation of the eCos C library for target 'linux' (the synthetic target) is known to fail when using certain older versions of GCC (eg GCC 3.2) due to a duplicate definition of getc(). * Compilation of eCos for targets 'atlas_mips***_5kc' and 'malta_mips***_5kc' fails due to various errors involving a loss of precision while casting. * Compilation of eCos for targets 'cma28x' and 'fads' fails due to a dependency of CYGPKG_HAL_POWERPC_MPC8xx on CYGPKG_HAL_QUICC. * Compilation of eCos for target 'iq80310' fails due to multiple coding issues within the platform support files. * The eCos tests 'pselect' and 'cpuload' may fail erroneously on some eCos targets (false negative). * eCos lwIP tests may fail to build when CYGDBG_LWIP_DEBUG is enabled due to a dependency on snprintf(). * The eCos tests 'except1' and 'kexcept1' may fail on certain processors where an exception is not raised in response to bad alignment (for example). * The eCos math library test 'pow' is known to fail on SH4 hardware when using the prebuilt sh-elf toolchain. The cause is unknown but the problem does not occur with older toolchains. * The MPC8xx test 'intr0' fails on many MPC8xx targets since the test is not generalised for correct operation will all MPC8xx CPUs. * The PSIM PowerPC simulator treats all data cache instructions as noops. The behaviour is benign with the exception of the dcbz instruction. It causes the eCos 'kcache2' test to fail on target 'psim'. * There are a number of minor issues with the eCos Configuration Tool: 84946 Configtool build progress bar inoperative 89778 Configtool platforms list is not sorted 1000619 Configuration tree does not respond to scroll wheel 1000716 Error launching GDB to run eCos tests
