*Very* newbie question: OE and Cygwin?

*Very* newbie question: OE and Cygwin?

[Tiller, Jason]

Hi, All, :)

 

[Main question: Can I use OE on cygwin to target a PXA270-based board?]

 

My name is Jason Tiller and I'm a software engineer at St. Jude

Medical, a heart-related medical device company.  I'm the only

software engineer in a division that builds high-intensity focused

ultrasound cardiac ablation devices for the relief of atrial

fibrillation.

 

I'm evaluating a new microprocessor for a next-generation power

generator.  We hope to use a linux kernel inside the instrument.  I'm

using a Logic Devices PXA270-based Zoom eval board.  I saw on one of

the LD boards that OE has support for this micro/board combination.

I'd like to try OE to build a kernel and throw up some simple apps,

but I have to do the host development in Windows, which means Cygwin.

 

In fact, the LD SDK is built on cygwin - they provide pre-built win32

gnu cross-tools that rely on cygwin apps.  I'm in the process of

updating my Cygwin installation with all of the tools that the wiki

(http://www.openembedded.org/wiki/RequiredSoftware) declares are

required for OE.  Some of them aren't pre-built Cygwin packages

(psyco, jade (but openjade is), sgmltools, docbook-utils, libsdl), but

it looks like the really important ones are there.

 

Should I expect a major headache in this effort?  My IT department is

very cautious, and they won't certify my (desperately underpowered)

Linux box for a net connection, so it's a lot easier to use my Windows

box for development.

 

Thanks for any heads up from a (hopefully) new OE user!

Without having ever tried it I'd say you might be in for some major
troubles. Cygwin in general is in my opinion messy anyway, and running
OE under a cygwin environment is not intended. You might end up running
into problems that nobody else has.. and that would certainly be
annoying. 

I think If you want to run linux on some embedded device you really
should have some proper linux based development machine as well. Also
be aware that if your work environment is that picky you might have
problems with the firewall when grabbing sources from various places.
Also you might have to update OE from the monotone repistory sometimes 
when there are important changes.. 

best of luck with your project anyway - the compulab board works fine
I am using one myself at work.

regards,
Tobi

I suspect you would be better off running Linux (ubuntu/debian, etc)
on a vmware virtual machine.  I've not tried cygwin, but just based on
the complexity of everything happening, it seems unlikely it will work
without a lot of hassle.

Good luck with your project.

Several of us have PXA270 Zoom boards.  The #oe irc channel on
freenode is a good resource if you need help getting started.

Hi,
if you gain some experience with OE on Cygwin it would be nice if you
leave some of that in the Wiki regardless of whether it does not
altogether or at least builts some simple packages.

Jason,

in theory, you might be able to get it (Cygwin + OE) to work. However,
after having spent months to get uClinux working under Cygwin I
*strongly* advice you NOT to use Cygwin for Linux target development.
I wrongly thought this would be the best bet to support my non-Linux
colleagues.

It planned out to be *much* easier to work under Linux, even for the
newbies. Good for them, good for me.

And the fact that your board vendor does use Cygwin (which is bad)
does not count if you want to use OpenEmbedded (which is good),
because OpenEmbedded gives you all you need. I.e. you would not want
to depend on some Linux "release" from your board vendor to build your
application.

The leverage of using Linux pays off on all sides! (test exposure,
build knowledge, build speed, power tools, ....). In fact, I also
consider Cygwin just another "vendor lock in".

These are just my two cents,

Leon.
