hi there,

where can i get some programming information for smartfirmware to develop small binary programs under it directly?

thanks in advance, MarK.

You mean like an operating system loader or something?

There is a tutorial in the works, spurred by the complete lack of one even for other Open Firmware implementations.

Not sure when it will be done.

Or are you thinking of something else?

well, yes, i'm playing with the idea of writing my own os, but it i'd like to start with stuff like to print something into the sf screen... simply something like programmers description... there are descriptions of the forth, but that's not enough...

bye, MarK.

I did some reengineering on this topic in the last
year, while starting to port NetBSD to the Pegasos.

I have a small library with all (or most) of the
OF_xxx() functions supported by SmartFirmware.
Additionally you need a special linker script and a
new compiler config file. It allowed me to compile
a test program which prints some messages (via
OF_write()) onto the screen.

When there is any interest in it, I could clean it up
and put it onto my home page this weekend. Or just
contact me for more info.

Making an OS based on SmartFirmware alone, without
using the Pegasos hardware directly, will be quite
hard, IMHO. The current SmartFirmware has too many
bugs in its current state. We were not able to make
NetBSD/ofppc run on it.

are you able to provide some of this information to me? or where did you get all the stuff?

thanks in advance, MarK.
