Subject: Pandaboard wifi on keeps forcing return to home screen
Print | Individual message | Show original | Report this message | Find messages by this author
Hello,

I built AOSP master for Pandaboard yesterday. As soon as I enable
wifi, it seems to get stuck in some loop where it keeps closing the
foreground app and returning to the home screen. Logcat shows:

I/ActivityManager(  265): START {act=android.intent.action.MAIN
cat=[android.intent.category.HOME] flg=0x10200000
cmp=com.android.launcher/com.android.launcher2.Launcher u=0} from pid
265

pid 265 is system_server. These messages are appearing at a rate of
several a second to once every few seconds. Any ideas why this is
happening and how can I stop it? Has anyone else seen this issue? As
soon as I turn wifi off, then everything goes back to working
normally. But I obviously want to be able to use wifi.

Did another build today, I am still seeing this issue. Makes it
impossible to connect to a protected wifi network since every time I
try to open the network settings it gets closed again before I can
type in the key. Is this just a pandaboard bug or is wifi setup from a
blank system (no cache or user settings) broken on all targets?

Hi Chris,

I can observe the same issue on my Pandaboard. I can work around it when I
turn on bluetooth before switching wifi on. Switching on wifi first leads
to the situation you described. Can you confirm this?

best regards

Rob

Yes, I see the same. The first time I tried your suggestion (bringing
bluetooth up first) the system hard locked when I enabled wifi. The
second time I tried, I was able to turn wifi on but the scan showed no
networks. The third time I tried, I was able to scan a network and
connect.

I wonder if we are alone with this issue or if other Pandaboards also show
this bug?
Could anybody else check this?

Hi, i think i solved this problem a few months ago, in the folder
device/ti/panda there is a file named gpio-keys.kl, the only line there
that says:

key 102  HOME   WAKE

i commented that line so the line that i have ther now is:

#key 102  HOME   WAKE

i had the same issue than you, and i even thought that it was the bluetooth
or the wifi, but it is about input events, when a click is performed, a
signal of going back to the home screen is sent to the O.S, i don't know if
that was the best solution, or why that line was there in the sources but
the only thing i know is that it solved my problem, it might be a solution
for you.

Best Regards.

Thanks, this solution works for me!
But I would like understand why. Do you know what this file and the entry
in it is for?

Hi, i'm glad it worked for you too, and i really don't know what is it for,
i was going to search about it but i haven't had enough time for it, if you
find something about it, tell me about it to have some info of that, the
only thing i knew was that it was sending input events when i was tracing
the system to catch the problem.

Best Regards.
