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
:-(

Damn, thats a shame.

I did a build yesterday and tried the 1.8@550175 blobs to match the kernel,
but as you say, black screen of nothingness. :(

When will you be pushing the panda kernel source?

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.

Subject: Re: State of PandaBoard

Which AOSP build _will_ work for PandaBoard (rev. A2 / OMAP4430 ES2.1) at
this time?

Currently I'm trying to get AOSP "android-4.0.4_r2.1" (IMM76L) with
imgtec-panda-imm76i-67545da7.tgz (which should also cover IMM76L) up and
running, following the instructions in device/ti/panda/README.
After proper udev setup, usbboot/fastboot work fine with my 4GiB SD card.

The kernel boots, but prints these errors on the serial console (no
graphics output):

[    4.933013] PVR_K: (FAIL) SGXInit: Incompatible driver DDK revision

> (279068)/device DDK revision (785978).
> [    4.943359] PVR_K:(Error): PVRSRVFinaliseSystem: Failed
> PVRSRVDevInitCompatCheck call (device index: 0) [451,

> [    4.956298] PVR_K:(Error): BridgedDispatchKM: Initialisation failed.  
> Driver unusable. [4795, drivers/gpu/pvr/bridged_pvr_bridge.c]

Any idea how to proceed? Should the branch android-4.0.4_r2.1 not work with
the IMM76L drivers? Or do I need to configure something?
[After starting with  full_panda-userdebug, I'm currently re-building
everything on full_panda-eng, but have no high hopes for it, hence my
question.]
Thanks! -Hagen

Is there a last known-good version? And if so, what precisely needs to

weeks?).

We have patches that should fix PandaBoard, as soon as I can get them

As a fallback, I have enough information available to recreate a

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.

(Thanks for the fast reply, Jean-Baptiste.)

After looking at the revision numbers for the driver and device DDKs,
currently I'm doing a "trial compile" of
 - android-4.0.4_r2.1  with
 - imgtec-panda-itl41d
Just to see if I happen to get something bootable with graphics.
If this does not work, I'll check different kernels.

Is it somehow possible to go back in the master tree with repo and do a
checkout of the status before the JB merge?

Thanks,

Info: Now I'm stuck in "fastboot flashall", at "writing 'system'".
On the panda tty this hangs with "sparse: write to mmc slot[0] @ 18432".

Flashing all other image parts works, only flashing the "system" image
hangs.
(Looks like an issue with the sparse file handling / flashing code to me.)

Multiple SD/MMC cards were tried, all three worked before before, with a
different system image.

Next trial is to see if I can manually create the "system" partition.
(Should not be too hard.)

After replacing the android-4.0.4_r2.1 versions of xloader and

"fastboot flash system" completes without errors.

Now I'm analyzing the boot logs and have a look at the file system.

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?

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.
