Blank screen when flashing to SGS2

[jammink]

May be related to https://github.com/andreasgal/B2G/issues/265

This appears with B2G commit 08de3eae29e29c1e9c6c262606f962f014b220ca Gecko commit 3ba41aed39d6307ab016535a1e30c758de69ebdd Gaia commit 544ea8917f9ba459d49635c735e3e9b8acbfd0d4

After a $make gonk && $ make flash && cd gaia && git pull origin master && make install-gaia and reboot, I am looking at a blank screen on my device.

Some bad things in logcat

Looks like we're failing to create a GL context, then (maybe) succeeding in using CPU fallback, but then apparently crashing.

Are you using ICS sgs2, by chance?

I am using Gingerbread on this particular device:

mozilla@mozillab2g:~/dev/nexus-sgs2/B2G/gecko$ adb shell cat /system/build.prop | grep ro.build.display.id | sed -e 's/ro.build.display.id=//' | tr -d '\r' full_galaxys2-eng 2.3.5 GINGERBREAD eng.mozilla.20120416.150632 test-keys

When was the last time you re-configured and flashed your kernel? There are some new files we need to pull off device for latest gecko.

[joneschrisg]

(i.e., make config-galaxy-s2 && make kernel, then flash)

[jammink]

I did that today, actually.

The issue is related to "libnetutils.so" pulled from device with newer stock FW, same as issue #261. Before this issue been fixed, a temp solution is to pull "libnetutils.so" from older stock FW.

If should be ok if sdk version < 15.

$ adb shell cat /system/build.prop | grep ro.build.version.sdk ro.build.version.sdk=10

[jammink]

I'm getting ro.build.version.sdk=10, so presumably this fix would work for me.

[jammink]

mozilla@mozillab2g:~$ adb shell cat /system/build.prop | grep ro.build.version.sdk ro.build.version.sdk=10

mozilla@mozillab2g:~$ adb shell cat /system/build.prop | grep ro.build.display.id ro.build.display.id=GINGERBREAD.XWKI4

[jammink]

tried on a newer phone and I'm still seeing the same issues:

ro.build.version.sdk=10 ro.build.display.id=GINGERBREAD.XWKE7

[joneschrisg]

@jammink can you paste the logcat from the newest attempts?

[jammink]

build from mrproper today:

logcat from XWKE7 GB device:
http://pastebin.mozilla.org/1577902

[joneschrisg]

Can you please list the exact steps you're taking to build and flash.

Phone

[jammink]

$ make mrproper $ make sync (presumably not necessary, but run anyway) $ ANDROIDFS_DIR=/home/mozilla/sgs2_firmware make config-galaxy-s2 $ make kernel $ adb reboot download $ heimdall flash --kernel boot/kernel-android-galaxy-s2/arch/arm/boot/zImage $ make gonk $ make flash $ cd gaia $ git pull origin master $ make install-gaia $ adb reboot

[jammink]

There were two phones.

Both were Samsung Galaxy SGS2, with ro.build.version.sdk=10:

1. ro.build.display.id=GINGERBREAD.XWKE7
2. ro.build.display.id=GINGERBREAD.XWKI4

[jammink]

I got a system.img (from the came commit and submodule sync) from @dhylands - and for some reason, when I'm flashing directly, it's actually flashing and loading ok.

That's a bit weird. It suggests that something in the build environment is influencing the image being built.

It would have to be something identical in three separate build environments then. One of them, my flash station for mozcamp, has a fresh B2G git clone, from yesterday.

@shianyow seems to believe it has to do with the firmware. But I have only these two phones (mentioned above), the XWKE7 was only bought a month or two ago.

Which version of ubuntu are you using? I happen to be using 12.04. If all 3 of your computers have the same version of ubuntu, then they'll all have the same version of build tools, which may be related to the problem.

And one of your phones has the same firmware version as mine.

It's probably worth collecting a set of md5sums on the files extracted from my phone and comparing those to the files extracted from your phone.

It's also possible that you need to make sure that the phone you're flashing was in fact the identical phone that you also ran make config-galaxy-s2.

If some of the prebuilt libraries are different, then firmware built for one phone might not work on the other.

Hi Dave

First off - thanks for your help. It's been a long day here testing busted build configurations - but I have come up with a list of "pitfalls" which are one of the things I have to present at mozcamp. Plane leaves in 3 hours :-/

I'm using ubuntu 11.10 on all three of my envs (a VM, and both a laptop and desktop which are running natively). So the build tools issue is a distinct possibility (although nexus s flashes normally and without incident on all of the above envs - also SGS2 was flashing normally until very recently).

The two S2s are the ones described in an early comment (not the same). We could do the MD5sum comparison at a later time - perhaps once my plane has landed!

[joneschrisg]

$ make gonk $ make flash $ cd gaia

Just building |make gonk| doesn't build gecko, as of recently. Try a |make gonk && make| step. Also, check 'adb shell ls /system/b2g'.

[dhylands]

It looks like Issue #280 should fix your build problem

[dhylands]

Hmm. Maybe not. Because the fix for that was ics specific
