Argh :(

The patch I committed shortly before release actually rips out the change
I made that caused unexpected rotation of the screen (which should have
been h2200-specific anyway) and instead just changes the way that the
cursor keys are interpreted, again for h2200 only. For reference, here's
the diff:

http://handhelds.org/cgi-bin/cvsweb.cgi/opie/libopie2/opiecore/device/odevice_ipaq.cpp.diff?r1=1.31&r2=1.32&f=h

Now, it's possible that some of the other changes we made to odevice*
caused this to happen. In any case, something must be wrong here, and I'm
not suggesting that I'm definitely not to blame for this :)

I'm pretty sure you can add h2200 to the list of devices that are not
affected by this issue. Interesting that you mention h3900 - is that
device in a state where it can happily run Opie using the 2.6 kernel? I
have not tried that for some time, perhaps I should.

Agreed. Unfortunately this is the first time I've heard about this
problem. I don't know how Erik feels but I am happy to fast-track 1.2.4 a
little bit if we are able to solve this problem soon. Alternatively I
would be fine with patching 1.2.3 in OE and also solving it for 1.2.4 when
it comes out, too, whatever works best.

> Note that it's not in the tracker.

Since you mention you don't have permanent net access I have now filed one
on the Opie side for this:

Right. However, if there are genuine bugs preventing Opie from being
supported I would like to hear about them so I can help solve them. I
guess I also need to get up to speed on Angstrom policies so that I can
contribute more directly (I hope they are well documented somewhere).

I am willing to fast track 1.2.4. But I would likely want most of the
bugs attached to the release shifted to 1.2.5, since I will likely not
get to many of them before putting out a fast-tracked 1.2.4.

  Well, I'm not talking about blaming, I'm talking about figuring this
issue out.

  Happily - depends. Otherwise, there's no pocketpc device which is
supported by 2.4 and not supported by 2.6. The worst is h3800 - SD support
needs revamp, etc. Still, it should at least boot. As for h3900,
battery support is not there for example.

  I don't have strong opinion here, except that it's worth to invest
time into solving this issue, as it is clearly on critical path
towards making a PR campaign on prebuilt OPIE availability for
Angstrom.

  No, apart from that unpleasant, but of course not really critical
bug, all requests from Angstrom maintainers were satisfied, so it is
only a matter of community interest and support.

  Not really, that's resume of IRC communications. But I think stuff
being done is primary, and bureaucracy afterwards, IMHO. Not talking
that it all just settles.

Of course. However I am currently stuck without a working device that exhibits
this issue, so I would appreciate any help from those who do have such
devices. In the mean time I guess I can try to just look at odevice* to see
if there is anything obviously wrong there.

BTW I did try building an Angstrom image for h3900, and it also does not seem
to be initialising the screen correctly on my h3970 - the backlight comes on
but otherwise it just stays black. I didn't connect to the serial console to
see how far it was actually getting. (Not that this is especially important
to our current discussion.)

OK. To open up an old can of worms, I did read an old comment just the other
day on the htc-pxa mailing list by Mickey saying that he did not want to go
back to the confusion of qt and non-qt packages for the same thing. I sort of
understand this, but where does it leave us with things like roadmap, SDL
games, etc.? I don't think we can completely eliminate these and still
provide the applications that users want.

Cheers,
Paul
