Hi all,
I'm interested in looking at some Bluetooth stuff on my OMAP 4460 Panda ES. Looking at the bug reports I don't see any Jelly Bean releases that have BT working properly on Panda. Is this correct?
Can you please point me to a release where BT and display/hdmi are working for Panda? It's OK if it is ICS.
I'm OK starting with binaries but I would much prefer to be able to build from source and reproduce any known-good bins. I have already built JB from the latest tip as well as the 13.07 manifest (display is working fine but BT doesn't work, bugs already filed). I tried the 12.07 Panda LEB (which I think was the last ICS release?) but the binaries supplied did not have display working even after running the install-binaries-4.0.4.sh script.
Thanks, Mike

Nicolas Dechesne may be able to help more directly, but mainline BT was never workable reliably on Panda.
The p-android stuff on omapzoom was meant to have numerous patches that actually made it work. At one point we talked to some guys from TI and got some patches, however they were patches against p-android-3.0 that not only did not apply on mainline but were 100% patching code that anyway did not exist in mainline, so we got literally nowhere with it.
The p-android stuff are busy history trees, so it is very hard to extract a coherent series that "fixes bluetooth". Even to do direct diffs at file level isn't easy since the files have all moved around and the 3.0 one we know worked is radically different than current mainline anyway. Some of the issues were down to PM related stuff and the p-android arrangements for that bear no relationship to mainline.
Anyway Nicolas may know more, but the best bet may be to find a TI Alumni who worked on it and get the skinny.

That's disappointing since an article on omappedia references the Linaro release and says, "Note: Wifi, bluetooth, YouTube, jpeg, video playback (both .mp4 and .3gp), and audio playback (both .mp3 and .aac) all have been verified as working in this release." You can see it here:

Looking at our test results, the bluetooth test failed in 12.07 release. A bug has been opened at that time: https://bugs.launchpad.net/linaro-android/+bug/987765
Adding Vishal in CC, who's probably know the bluetooth status in Linaro Android builds better than me.

Mike's saying even video didn't work when he tried that.
Reading that bug it sounds like a firmware issue in the image. I say in the bug it's working on kernel side at that time.
However like the video problem, it sort of hinges on the meaning of "working".
HDMI and DVI on Panda have "worked" to some extent for a long while. But they've never worked properly dual-head and in fact because they share a PLL for the pixel clock, they'll never work outside of special conditions like same monitor and resolution. Last I saw of it there's a behaviour in HDMI hotlug detect handling in the driver that means some monitors won't be seen as plugged, because they delay sending hpd by up to 1s (I have one of these monitors). The code in the Panda release was forward-ported from 3.0 DSS stack on omapzoom (since that's the only thing TI had on offer with working Android SGX) and that deviates hugely from mainline DSS, so any improvements in this area didn't get transplanted.
Bluetooth is similar on mainline basis, it was able to work for a while but when hammered it fell over.

Sounds like I'm out of luck for finding a build where things Just Work. Thanks for the inputs everyone.

Yes. This is true. We have not worked on fixing BT on JB.
Can you please point me to a release where BT and display/hdmi are working for Panda? It's OK if it is ICS.
Even on ICS it was partially working. File transfer resulted in crashes on 4.0.4. You can try this release which is based on 4.0.3 : http://releases.linaro.org/12.03/android/leb-panda/
It was working well on GB if you are interested:

12.07 did not need any acceleration binaries since it was based on 3.4 kernel where SGX was not ported back then. Since we were not making any progress with 3.4 kernel, we moved back to 3.2 kernel.
Nicolas Dechesne may be able to help more directly, but mainline BT

well, not really... i have never really paid too much attention on BT for Panda. For a while we had some support from the Connectivity team, and things 'kinda' worked. Andy spent some time fixing a bunch of issues in our TI kernel at that time. But around the same time when ICS came up, things stopped working, and we were left with no support .. and BT wasn't clearly something we cared too much about ;-(
