How to build User variant in imx8qm-Android9-Auto ?

[amit251291]

Dear all,

We were going through BootTimeTuning Section 8.6.3 of Android user guide. We understood from it that we can build User build variant to optimize boot time by 0.5 sec. 

So when we were checking different 'lunch command' combinations for imx8qm-Android9-Auto we didn't find this build variant present.  Only Engineering and Userdebug are present. 

Could you please let us know how to build 'User' variant for this ??

Here are present lunch combo: Relevant combos are highlighted

Hello Amit Kulkarni,

Would you confirm which BSP you are using? Is it P9.0.0_2.1.1-AUTO-ga? There should be a mek_8q_car-user lunch option available, but I would need to doublecheck if for some reason it was not defined on that specific BSP.

Regards,

Dear gusarambula‌

Thanks for you reply.

Yes BSP version is android_p9.0.0_2.1.1-AUTO-ga. I checked and i didn't find any mek_8q_car-user option in the 'lunch' command. Only mek_8q_car-eng and mek_8q_car-userdebug are available. 

 For us changing the build variant is very important for Boot Time tuning. 

Request you to check and let us know.

Hello Amit Kulkarni,

I'm testing building this BSP with lunch mek_8q_car-user. Apparently it does take it as a valid profile, but I'm asking our experts if this profile is indeed valid and correctly setup, as there are a couple of threads with problems with the user variant.

Regards,

[amit251291]

Do you have any update gusarambula‌ here ?? We are stuck!

Hello Hello Amit Kulkarni,

I'm still waiting for an update from our experts. My apologies for how long it's taking. I will let you know as soon as I have more information.

Hello gusarambula‌

Okay, Thank you so much. 

[gusarambula]

Hello Amit Kulkarni,

My apologies for the delay. I asked our experts and both the "user" and "userdebug" build showed no boot failure. Even tough these are not listed these would be valid variables.

Would you please test with the "user" variant and provide the error log if there's any?

Regards,

[amit251291]

Thanks gusarambula‌ for valuable input. 

I will build this now and update here at the earliest
