Bouncy robot powered by mspgcc+olpc/Sugar+msp430

So far mspdebug Linux tools "work" in OLPC's XO computer using the
directions in <br>
<a href="http://processors.wiki.ti.com/index.php/OLPC_XO-1" target="_blank">http://processors.wiki.ti.com/index.php/OLPC_XO-1</a> (major overhaul
today, courtesy of a cold/flu)<br>
<br>
1) I beg mspdebug people to vet excessive heresies this noob might
have introduced in the How-To in that page. <br>
So far I am managing without -mcu - or -gdb. <br>
I actually have no idea what those are for, or if their
unavailability explains my so far failure to UART, or if we should
care... (for many things, it ain't broken...)<br>
<br>
2) Fedora packaging people: any way to package <br>
mspdebug
msp430-libc
msp430-binutils
msp430-gcc
msp430mcu
msp430-gdb ? <br>
What gets downloaded through yum channels in the XO is very, very
outdated, and conflicts (cf. mcu and libc).<br>
Please feel free to forward, as I have no access to "real" Fedora
people - don't even know where to look for them without making a
nuisance of myself and undue noise, and certainly do not know who
could maybe make a "package"(?) usable for the XO. Will this be
fixable for the next OLPC OS?<br>
Daniel?<br>
<br>
3) Robotics, Science, Sensors OLPC, IAEP people, please, if you
could test the GCC toolchain? <br>
You do not need to have a Launchpad on hand. I am trying to catch
bugs and usability issues. Are the instructions clear? as much as
possible figuring out snags so it's easier for kids and normal
people.<br>

The brains of this "bouncy" are an MSP430 microcontroller (a lowly
g2152) controlling a L293 dual H bridge, senses two switches. Its
brawn a couple geared DC motors on 9V PWM in an askjerry tricycle
frame. Not counting shipping, less than USD $10 total. Coded in an
XO-1 all the way. Enormous thanks to the mspgcc folks that helped me
figure things like how to use more than one switch...<br>
