About Ecos building
For ecos building the following packages are to be installed:
tk8.5 tk8.5-dev tcl tcl8.5-dev
Without these packages the following errors will appear during building:
configure: error: unable to locate Tk config file tkConfig.sh
error: unable to locate Tcl configuration file tclConfig.sh
Let's assume that there is a directory ecos-3.0 which was get from the archive "ecos-3.0.i386linux.tar.bz2".
а) Let's create the directory build in ecos-3.0 and go into it.
б) Let's run the following:
./../configure --prefix=$WORKING_DIR/ecosInstall --with-tcl-version=8.5
--prefix is a path where ecos is to be installed after command running make install.
--with-tcl-version - is the version number.
в) Let's run the following:
make sudo make install
Ecos is installed. Now we can start with the building of applications.
About Redboot building
Here is an example of redboot building for the targets named malta_mips32_4kc (MIPS Malta board with Mips32 4Kc processor).
The list of the доступных целей for building one can find in ecos-3.0/packages/hal/
or one can run the following command:
export ECOS_REPOSITORY=PATH_TO_ecos-3.0/ecos-3.0/packages PATH_TO_ecosInstall/ecosInstall/bin/ecosconfig list
There is a graphic version of ecosconfig - Configuration Tool from the file named "configtool-2.11-i386.tar.gz"
#) Let's create the directory redboot
#) Let's set the path to the file ecos.db and the path to the cross compiler:
export ECOS_REPOSITORY=PATH_TO_ecos-3.0/ecos-3.0/packages export PATH=$PATH:PATH_TO_gnutools/gnutools_4.3.2/mipsisa32-elf/bin
#) Let's create a file with the building configuration for this target:
PATH_TO_ecosInstall/ecosInstall/bin/ecosconfig new malta_mips32_4kc redboot
#) Let's import the configuration redboot for this platform:
PATH_TO_ecosInstall/ecosInstall/bin/ecosconfig import PATH_TO_ecos-3.0/ecos-3.0/packages/hal/mips/malta/v3_0/misc/redboot_RAM.ecm
#) Let's resolve the problems:
#) Let's create a project tree:
#) Let's build:
After running of the last operation the redboot image for the firm ware will be in redboot/install/bin
