i.MX6Q (android 7.1.2) : very weird behavior - help me. part I.

[jasonoh]

Good Day! Everyone!

We have a custom i.MX6Q board. (DDR + SD I/F)
We have ported u-boot, kernel, android to our board by following Android_User's_Guide.pdf.(android_N7.1.2_2.0.0)
Then we have programmed images to 16GB SD(micro)card using ~/myandroid/device/fsl/fsl-sdcard-partition.sh.
The very first booting is OK. Everything is fine. Please check 'First-booting.mp4' in part I.

But after second(third, fourth..) booting, there are only status bar and back button except all gone.
Please check 'After-Second-booting.mp4' in part II. If you have experienced this, I would like to hear some advice.

Best Regards.
Jason Oh.

Hello,

Can you please share your log. Probably is a hardware problem.

Best Regards,

Good Day, Diego!

This is Jason Oh.

I have ported Android_N7.1.1_1.0.0. 

It works as I expected. There is no problem. (but, many "avc:denied ...." messages <= I am a novice in SELinux area.)

In my opinion, it seems to be a GPT partition problem.

The time for this project is short, and I have decided to porting Android_N7.1.1_1.0.0.

The next step is porting an audio codec. (WM8960).

Dear Diego, Are you a NXP's staff?

If so, please help us(me) a lot in the future.

Thank you very much.

Best Regards.

Jason Oh

Hi, Diego.

Thanks for your reply.

Yes. I thought it was a hardware problem.

But, when I have ported Android_M6.0.1_2.1.0, there is a no problem. Everything is OK.

So, I am currently trying to port Android_N7.1.1_1.0.0.

I will let you know when it finished.

I think there is a problem between GPT partition and SD card in our system. (<= just guess).

Best Regards.
