Hey folks.
I played around a bit with brickOS a couple of years ago but never
got around to do anything serious. And now I thought I'd look into
it again, if only for the joy of low-level coding.
So I noticed, like others before me, that brickOS straight from
CVS won't compile (with any recent version of gcc) without Jochen's
opcode patch. So I wonder what the development status is at the
moment, and if I should volunteer to get the code to a state where
it compiles wih gcc 4.x without warnings.

Carl,
Welcome! If you have the time and the interest we welcome your
spending time on this.
As you can tell there has not been much activity here in a while... ;-(

Hi Stephen, 2*Michael and others,
I've (finally) started playing around with brickOS again. My RCX and
almost all of my Lego is in storage a long long way from here, but
that may actually be a good thing in this context.
I've applied Jochen's patches and Rodolphe Pineau's OS X patch, fixed
a few warnings with gcc 4.4, updated the doxygen stuff and added some
code to count edges in the signals detected by sensors (useful for
counting the number of times a touch sensor was pressed, even at tens
of hertz or more - I used it to accurately measure the position along
a long gear rack). I've gathered the patches at http://carl.troein.com/
The documentation is in need of some loving care, but there's some
other stuff I'd also like to play around with. We'll see how it goes.
Cheers,
//Carl

Hi Carl,
I think we all want to get (or have it already) a NXT brick. BrickOS was
not changed in the last year, as I remember. But it is a great way to do
real programming and I wish to have someting like a nxtOS. :)

That sounds great for me. I use my good old RCX and brickOS, actually
with a gcc < 4.x toolchain. It works, but if it could work better...
Regards,
Michael

Santa thinks I haven't played enough with my RCX since I got
it, so he won't give me a NXT just yet. ;-)

Aside from some signedness warnings and a missing function for
converting unsigned to float, brickOS compiles nicely with gcc HEAD.
Patch: http://carl.troein.com/brickos/ct_signedness.diff
And I should test with some slightly older version of gcc too.
