State of PandaBoard Jean-Baptiste Queru 7/10/12 6:18 PM
There's a known issue with graphics on PandaBoard, where the display
is entirely black.

I suspect that's related to the changes that were done in Jelly Bean
around triple buffering.

My understanding is that someone is already working on updating the
graphics libraries. In the meantime, PandaBoards won't display much
:-(

I always build the PandaBoard kernel directly from AOSP, so the kernel
source is always available. The panda kernel hasn't changed since ICS:
I can't merge newer upstream kernels as that breaks the graphics
driver, and I can't update to a new graphics driver as I don't have
any newer graphics libraries that work on PandaBoard.

Ah, fair enough. I'll await new graphics libs then. :)

Thanks for your reply.

Re: [android-building] Re: State of PandaBoard Chris Bainbridge 7/12/12 6:31 AM
I also did a build yesterday and discovered this black screen issue.
Is there a last known-good version? And if so, what precisely needs to
be checked out? Any idea how long before this issue is fixed (days?
weeks?).
Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 7/12/12 8:15 AM
PandaBoard can't be used from tagged releases. Only the master branch
can be used.

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 7/12/12 8:16 AM
We have patches that should fix PandaBoard, as soon as I can get them
reviewed and merged.

As a fallback, I have enough information available to recreate a
last-known-good state. I haven't had time to do that, though.

JBQ
Re: [android-building] Re: State of PandaBoard Will Tisdale 7/12/12 8:18 AM
Good question. Probably none currently, because the JB code has been
merged into master, and it was only master which was working. (As JBQ
just posted).

But now because JB and pandaboard graphics are broken, you can't get a
working build from master, unless you happen to have an old, pre JB
tree kicking about. I guess you could build JB master without the
libs, but it wouldn't be ideal.

The other alternative is waiting for the new libs.

We have changes in process that are expected to fix things. If those
don't work, we'll find a way to go back to the last-known-good state.

Yes, I noticed.

To test a component for a customer, early next week I need a debuggable ICS for PandaBoard - but any sub-version will do. Have you e.g. got a repo branch/tag or a bunch of git IDs for me?

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 7/13/12 9:58 AM
If you hunt around in all projects for the "ics-plus-aosp" branch and
create a manifest for that (which should be mostly similar to what
master-dalvik had before the Jelly Bean push), that might work. Maybe.

Re: [android-building] Re: State of PandaBoard Martin Heller 7/20/12 5:55 AM
Hello,

do you have an idea when AOSP builds for PandaBoard will be fixed?
And will the master branch (i.e. 4.1) be fixed or a working tagged
release of 4.0 will be made?

Thanks

We're currently stuck on the code review of a platform change to
disable VSync on hardware that doesn't support it. Until that change
gets approved by the maintainer of that code, we can't move forward.

You can capture the state of your repository and produce a manifest file
with SHA-1s that others can sync against:

repo manifest -r -o my-working-source.xml

I've just added a branch ics-plus-aosp that matches the state of the
AOSP master before the Jelly Bean release. In quick testing, it seems
to work on PandaBoard.

If this is similar to the kernel markers, gedeced79 means "Git commit

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 9/28/12 8:36 AM
For me (ES EB3), the kernel boots, but the graphics system fails to
initialize, in a way that looks like an incompatibility between
userland and the kernel.

I'm pretty sure that it was working when I prepared those files, but
that was weeks ago.

Do things still working when going back to the previous kernel and
graphics libraries?

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 9/28/12 8:47 AM
In bad news, it looks like the old kernel and graphics binaries also
fail (same errors). I'm guessing that something else changed since
early August.

Re: [android-building] Re: State of PandaBoard Adrien Grassein 9/28/12 9:02 AM

Yes everithing is ok with previois kernel and drivers with android Master.

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 10/4/12 11:01 AM
I've tested locally with the previous kernel and the previous graphics
libraries, and things are working for me. At least we know that the
rest of the master branch is OK, so whatever issues we're having are
either the kernel, the graphics libraries, or both, or an
incompatibilty between those.

Now, surprisingly, I don't manage to get any logcat output at all from
the most recent kernel I submitted. That's definitely not expected,
and that would suggest that the kernel is bad. I'll try to regenerate
one from source. Has anyone rebuilt that same kernel from source and
gotten it to boot at all (regardless of graphics).

Yes, I rebuilt the kernel from source from both commit (the previous commit, and the new one). As expected, the 'previous' works and the new one not.
Also, I try to merge ti-omap4 branch onto the ti-omap4-panda branch, and this not works too.

Re: [android-building] Re: State of PandaBoard Jean-Baptiste Queru 10/4/12 12:47 PM
I think that the situation with not having logcat is a red herring.
I've also had logcat work fine with the latest kernel, and I've had it
fail with the previous one.

I'm digging deeper.
