	+	====== eCos ======
	+	eCos (embedded Configurable operating system) is an open source, royalty-free, real-time operating system intended for embedded systems and applications which need only one process with multiple threads. For more information look at [[http://en.wikipedia.org/wiki/ECos\|Wikipedia]] or [[http://ecos.sourceware.org/\|eCos homepage]].
	+
	+	Plese help me with eCos testing and developing new eCos drivers. Patches are gratefully welcome.
	+
	+	Thanks,
	+	Michal Simek
	+
	+	===== How to compile eCos =====
	+
	+	* choose build->templates
	+	* choose your board -- the name for reference board corresponds with table at [[ecos:designs\|reference design page]]
	+	* choose package net for eCos, network support
	+
	+	{{:ecos:ecos1.png\|Ecos template}}
	+
	+	* choose proper location for your ecos project
	+	* ''sw/user-project'' folder is used for this purpose
	+
	+	{{:ecos:ecos2.png\|Ecos saving folder}}
	+
	+	* check your platform settings
	+	* in this reference design, you have to disable GPIO_2 periphery because it implements system reset functionality
	+
	+	{{:ecos:ecos3.png\|Turn of GPIO_2}}
	+
	+	* build your eCos Build->library
	+	* check your build output
	+
	+	{{:ecos:ecos4.png\|Build output}}
	+
	+
	+	* if you have any problem with compilation, check your setting or contact me
	+
	+	* your project folder contain some folders and file
	+	* ''ecos_install''
	+	* ''ecos_build''
	+	* ''ecos_mlt''
	+	* ''ecos.ecc'' -- project settings
	+
	+
	+	* currently you have prepared eCos libraries for your first application powered by eCos
	+	* for first application with eCos follow the [[ecos:ecos:own\|manual]]
	+	* for useful application (e.g. shell) look at [[ecos:ecos:app\|here]]
	+	* for test compiling look [[ecos:ecos:tests\|here]]
	+
	+	===== Problems =====
	+	==== Unsupported fatal-warnings ====
	+	* find CYGPKG_INFRA_LDFLAGS_ADD option and remove this option from your setting
	+
	+	cdl_option CYGPKG_INFRA_LDFLAGS_ADD {
	+	# Flavor: data
	+	user_value -Wl
	+	# value_source user
	+	# Default value: -Wl,--fatal-warnings
	+	};
	+
	+	==== No build directory ====
	+
	+	make: *** /home/projects/ecos/sw/projects/RedBoot-gdb/redboot1_build: No such file or directory. Stop.
	+
	+	* Solution: Build->Generate build tree (CTRL+F3)
	+	* this re-creates folder structure in your project again
	+
	+
	+	===== Know limitation =====
	+	* based on old source code - I have updated version but there is issue with eCos, RedBoot work well
	+	* weak driver support
	+	* vectors are placed by linker script directly to BRAM which break BIN file loading
	+	* CPU without MSR instruction is not handled correctly
	+	* weak optimalization on Microblaze version
	+	* based on older ecos version -> update to latest version
	+	* acsupport/config.sub - missing Microblaze architecture
	+	* test, test, test
	+	* do not use printf in your application, this cased system crash, you can use diag_printf ->seems that problem is with malloc or in serial driver
	+	* cpu handling is not clear, for example parameter --mcpu is filled from generic platfrom not from cpu
	+	* currentry is supported only one version of MB but this is base support which could be used for higher version

	+	* ''app.c'', ''Makefile'' and ''xmd.ini''

	+	====== eCos tests ======
	+	eCos provides testing facility which can automaticky test your design for features which you turn on. Here page provides the test results.
	+
	+	===== Building tests =====
	+	* Build->tests
	+	* check your building output
	+
	+	* tests are placed in project in ''*_install/tests'' folder
	+	* you can run all tests
	+	* every test shows up result
	+
	+	* eCos provides an automatic testing facility, which could be used, but so far with no success (on Microblaze)
	+	* any help in this area is greatly welcome
