Android 10 crash during boot animation

[andrew_questps]

Hi All,
For my work I have been porting the Android 10 changes from the 10.0.2.3 release onto a custom imx7d device, we already have a working 9.0.2.2-ga release, but we are interested in the new additions to Android 10. We have a requirement in our project to not get too far behind the Google releases and with Android 11 soon to be released we did not want to be out of support from Google with regards to security fixes and kernel patches.

When I run the release on Android 10 - with the changes required to get it to build in that environment similar to the imx7ulp - I am having an issue where the boot animation crashes in one of the NXP supplied drivers /vendor/lib/egl/libGLESv1_CM_swiftshader.so

After this happens there is a period of 30secs where nothing is displayed before an Android prompt that has:

Android System
There's an internal problem with your device. Contact your manufacturer for details.

So it doesn't seem that Android is unable to render anything, just that it crashes.

Can you please help me with this issue?

I have attached the relevant section of the log but the excerpt is this:

Hello,

Please accept my apologies, but Android 10 is no longer supported for this device because the characteristics of the MPU might not be the most efficient ones for Android 10, for which it will be helpful to consider switching to a more powerful MPU which is supported on recent versions of Android from the i.MX family, besides, this one does not have a GPU: https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-proces...

In case you still need support on the porting for this device, please contact professional services: https://www.nxp.com/support/support/nxp-engineering-services/professional-engineering-services:PROFE...

Have a nice day.

BR,

Ivan.

That's a shame considering it basically seems to run until this crash. I guess I will just try to fix it then when i have some free time

It's a bit late to decide to change CPUs to a more expensive one in the project now, and then rework boards etc and our usage doesn't require a grunty GPU, we aren't making a phone.

I guess I find it disappointing that NXP support the devices for such a short period.

Hello,

The i.MX 8M Nano is not an expensive solution and a viable one compared to the 7 dual. And, it is supported on newer versions of Android, please refer to the following link: https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-...

But, if you still need help with customizing Android 10 for the i.MX 7D, you can find our professional services on the following link: https://www.nxp.com/support/support/nxp-engineering-services/professional-engineering-services:PROFE...

Have a nice day!

BR,

Ivan.
