recurse, yum

Hi! In lesson 4, I might have only used the definition of factorial that used the word 'recurse', and just skipped 'recursive'. 'recurse' is ever so much nicer, don't you think?

<Mitch> I don't have a strong opinion about recurse vs. recursive. Both get the job done.

Thanks for the awesome intro to forth!

<Mitch> You're welcome, glad you like it.

Questions on building Forth firmware

How do I build the firmware? I want to add some new words and some games.

Answer:

svn co svn://openbios.org/openfirmware
cd openfirmware/cpu/x86/pc/olpc/build
make

The whole process takes less than a minute if you have a reasonably fast Internet connection.

You can put new "fload" commands in openfirmware/cpu/x86/pc/olpc/fw.bth to include the files defining your new features.

Thanks.

What I am trying to do is automatically, during a boot, over-clock my XO. What file can I modify to execute my new word or words?

How do I get this new build into my XO?

Answer:

Put the new image on a USB key (for example in a file named "new.rom") and type:

 ok flash u:\new.rom
