[Peeweelinux] embedded linux for robots... newbie questions

[vwbug19]

bonjour!
my hint is never use the flash card for a ramdisk or swapfile as it will
qiuckly wear it out to an useless card ,remember the flash card have finite
life :)
as for frame grabber and camera ,you didn't mentions what type and model?
and you should stick to other like nano-x instead of xfree86 as xfree86 is a
real disk space hog but you shouldnt need xwindow as the robot doesnt need
it and there are framegrabber software that can be run from console
mode,this will make the linux distro much smaller

> hello,
> I'm a french student in an engineering school and as in many of these,
there is a robot club ("E=m6" if there are some french people here!) to
which I participate. I am in charge of a PC/104 on which I'd really like to
install linux. I have some experience (I'm far from an expert though..) on
linux itself but not on embedded linux. I've read many of the mails of this
list and found some interesting points. But what I would really need is
rather some piece of advice. Here's an overview of our devices:
> PC/104 board from 'rtd usa' (media GX 233, 128MB Ram)
> sandisk 48 or 220 MB Flash card (PCMCIA card)
> ATA adapter for these PCMCIA cards
> Frame grabber and color camera for image recognition
> Now for the questions...
> 1) I've had a look to some articles about flash devices, but these were
generic. They talked about NOR and NAND flash memory types. Which is mine??

for the root tree and ramfs for /tmp, is it true?

exclusively a Ramdisk?

linux is done thanks to a host. At least it seems to me it is necessary for
building the fs. But as we will need to use the frame grabber would it
better to develop our programs directly onto the PC/104? (by the way would
it be possible to redirect information from the frame grabber to the host
with somme parallel cable or so?)

choice?

refer to old devices and I suppose what we luckely have shouldn't be that
obselete...
