[zhangmike]

Hi;

My board is imx6q sabresd.

Enviroment: android9.0

My kernel starts in half and then stops.

log is here:

Hello Mike,

   Don't use android 9.0 BSP, for i.MX6Q, The highest android version is android 8.0.

Hope above information can help you.

Have a nice day!

Hi Wigros:

    Why?  I watch the document of android_p9.0.0_2.2.0-ga_docs, and it says can use android9.0 bsp in this document. this item is very important for me, help me please.

Sorry! Mike,

  I just confirmed it with member from android design team, yes, right. p9.0.0_2.2.0_ga supports i.mx6/i.mx7, and it is the latest one.

  I checked your booting log listed above, It is hard to find where the issue come from. Because there is no error mesage in log.

  So I think it is better to test images on i.MX6Q SabreSD board.

In addition, I find you use 2 GB memory, which is different from that of SabreSD board. So you can spend some time to check if the issue comes from DDR configurations.  On our i.MX6Q Sabre AI board, 2GB memory is used, you can compare your DDR configurations with that of Sabre AI board.

Hope above information can help you!

BR,

Hi Wigros:

    Thank you to support some information for me.  But I have some questions.  Kernel is running failed only,  and android doesn't init.

and I compared the booting log with normal booting log of android N. I find caam doesn't run in android P booting log. what is caam?

left: kernel booting log in android P                                                                right: normal kernel booting log in android N

Thanks!
