black screen after the app start

[serge c]

Dear all,

I have a customer who ask me to try his application from store.

For that we have install lataste nugat version on an intel NUC 7i5BHNK.

In app setting I turn ON the app compatibility with Arm library, 

Right after the application start I get a black screen

Then after some time I get a message application has stop, open app again.

How to know the reason of that back screen or is there any way to know the reson the app crash even if we a&re not the author ?

regards

Boot in Live DEBUG mode or in DEBUG mod

[ALT]+[F1] to switch to console

cd data

mkdir x

[plug additional flash drive, you will see which sdx1 is assigned where x=a,b,c,d,]

busybox mount /dev/block/sdc1 x   (NOTE: sdc1 may be sdd1 or something else, you have seen this when pluggin the additional flash drive)

cd x

cp /data/log.txt logcat.txt

dmesg > dmesg.txt

dumpsys SurfaceFlinger > dumpsys.txt

Please provide information about the app you are using, so that I can cross-check on other Intel GPU hw.

Consider that if the problem falls in the category RGBA/RGBX texture surfaces rendering

there are currently issues in mesa library, (in)visible with Gears/Rajawali on Intel GPUs.

and there are patches by Chad Versace under review in mesa-dev, 

so if that is the problem it may be solved in mesa-dev and we hope also in next stable release mesa 17.1.4

Dear mauro,

I try too boot in Live debug mode as you suggest. When do I kown debug mode boot is completed ? 

At which phase should I press CTRL + F1 ?

What I have notice is that when I boot in debug mode only a single time and then reboot my PC, I am not able to boot anymore normally the PC keeps on restarted after displaying Android message.

I ma not an expert in Android

Dear Mauro,

I start Android-X86 7.1 version in debug mode as you mention.

Then after some time I get the flicking cursor at bottom left of the screen. Does it means I am automatically in console Mode ? because ALT+ F1 has no effect on my side.

Then I continue to enter command as you suggest , when I insert mu USB I can see sdc: sdc1 

Then I enter the following :

cd data

mkdir TEST

busybox mount /dev/block/sdc1 TEST   

When mounting I get error message : " mounting sdc1 on TEST failed. no such file or directory"

Any idea ?

After all comand gets enter, how to run the android then or start the app I want to see logs ?

Sorry for those question but get lost with this sequence and command

Thanks for help

regards

Serge

Hi serge,

I've posted information about the issue in the other thread "URGENT HELP : MashMallow back to android icon all time", because I searched for 'Dragonball' when replying

Cheers
