Running BrickOS/LegOS at Home
When running BrickOS/LegOS at home in your Microsoft Windows
95/98/NT/2K/Something environment you need to install a cygwin shell
and a Hitachi-H8 cross compiler(ie a compiler that can generate code for another processor).
You can use the same pre-packaged cygwin-legos.zip used in the
lab-computers. Then you need to:
- Download the cygwin-legos.zip package (56 MB). Unpack
it into the root of C:. This will unpack a cygwin installation
into the directory C:\cygwin-legos. It is important to unpack exactly
to this place, otherwise the paths will not work.
- Download the registry patch cygwin.reg. This file contains data
that cygwin needs to find its paths. Either run it directly when
it is fetched or double-click on it afterwards, this will add
the needed keys to the registry.
If you like to have more control over what you are doing you
can install cygwin and compile the cross-compiler from
scratch (if you find my instructions less than optimal you may be
helped by these):
Now choose if you would like to install the newest brickOS version or the older (and more stable) legOS version. If you choose brickOS continue with steps 3 and 4 in the instructions above. If you choose legOS continue by following the instructions here.
- Download LegOS from the assignment page legOS.zip. It is preferable to use the
legOS.zip package from the lab assignment since we needed to
modify the package somewhat to get everything to work (ie. you
don't need to do the modifications yourself). If you are using
the legOS.zip package on the lab page you can use
WinZip or some similar program. If you choose to download the
original LegOS-0.2.4 or LegOS-0.2.5 packages you need to use the
tar xvfz command in your Cygwin shell.
- If you installed the cygwin program somewhere else than
directly under C: you need to open
Makefile.common in your LegOS directory and set the
line containing TOOLPREFIX= (the one under #NT
row) to
TOOLPREFIX=PATH_TO_CYGWIN/usr/local/bin/h8300-hitachi-hms-
where PATH_TO_CYGWIN is where you installed the cygwin
package.
- Go to the LegOS directory and type:
make realclean
make depend
make
cd util
make strip
Hopefully everything should be compiled without any problems.
- Follow the rest of the instructions in the Programming Lego Mindstorms using LegOS assignment on how
to compile and download the kernel and your written programs.
To run
BrickOS/LegOS at home on a Linux environment see the LegOS on Linux
installing instructions page. The instructions should work, but the tools mentioned are a bit old.
If you run Debian more recent instructions are available in
http://brickos.sourceforge.net/docs/install-Debian.html
More updated and detailed information on how to install and run
brickOS/legOS under Linux will be added when available.
