Androdi 11 build for Pixel 5 (redfish)

[Jim]

Hi,

I try to build AOSP from source for a Pixel 5, but I face face some issues because my phone does not reboot after flashing it.

I tried several tags, but always the same behavior.

Here is what I do for android-11.0.0_r32 :

1 - check at https://source.android.com/setup/start/build-numbers the corresponding factory image : RQ2A.210305.006

2 - download and flashed the factory image -> OK

3 - download AOSP repoitory android-11.0.0_r32

4 - download the corresponding vendor image (https://dl.google.com/dl/android/aosp/google_devices-redfin-rq2a.210305.006-a3096c4f.tgz) and extracted it in android repository

5 - lunch aosp_redfish-userdebug

6 - make

Then execute fastboot flashall in $OUT folder to flash the image.

But the phone cannot boot, and is stucj in android black screen.

Does anybody knows what I did wrong ?

thank you !

You may need to download additional vendor blobs:

found the solution: need to execute fastboot flashall -w

Hello, 

Did you put the driver binaries into the AOSP folder?

https://developers.google.com/android/drivers

[Jim]

thank you for your answers. 

As explained before, it now works thanks to -w option to flashall that was missing.

Concernign the vendor binaries, I only use the Google vendor image, not the binaries from qcom. The reason is that during AOSP build, vendor image is NOT built: it just uses vendor.img from google driver. Thus, qcom binaries is not used in this process.
