A good starting point is the L4Re documentation [0]. This should get you started. > Like how to make a new program outside the main program of "hello" (i am > using hello code all of this time to experimenting). And also how to access > the memory of the host computer using L4Re code. Just create a new directory within you pkg directory. From there you can call '../../mk/tmpl/inst' which installs the default directory hierarchy and Makefiles. > Because the main goal of the project i am working on is be able to access > the GPIO of Pandaboard. The io server already provides infrastructure and the API for GPIO drivers. Please have a look at the existing BCM2835 and OMAP3 drivers. > And also, is there is any way to recompile L4Re without recompiling all of > the module it use.

Change into your pkg's directory and call 'make -jX O=/path/to/obj/dir' or from your build directory you can call 'make -jX S=YOUR_PKG_NAME'. Note that the latter will not check and rebuild the pkg's dependencies. Matthias.
