Building for Crosshatch/Blueline Android 10

[Surge Raval]

I've been trying to build android for the pixel 3 devices. Both sargo and bonito build successfully and boot. However, crosshatch and blueline do not.

This is what I've tried and has worked on sargo/bonito.

Pure aosp 10 r2 branch sync, lunch aosp_$(TARGET_PRODUCT)-userdebug. And making dist and otapackage (otardppackage)

the 3/3xl reboot from recovery, get to white Android splash and reboot to fastboot immediately with the reasoning on the fastboot screen given as "reboot to bootloader".

Has anyone successfully built for crosshatch and/or blueline on Android 10, and if so could you list your steps..

I should note, crosshatch will boot if I make an update zip with a super_empty.img and manually fastboot in the order of boot, dtbo, vbmeta (thehen reboot to fastbootd) flash super_empty over super (system_b) then flash product, system, and vendor.

This seems like it shouldn't be the only way. I'm looking for a way to do this via sideload using update_engine as the facilitator rather than fastboot.

Thanks

Yes, crosshatch for Pixel3XL works fine. Your Pixel3XL may have older version of bootloader. You need to upgrade bootloader first before flashing AOSP phone image.

Download the production phone image  https://dl.google.com/dl/android/aosp/crosshatch-qp1a.190711.019-factory-130c70be.zip




unzip crosshatch-qp1a.190711.019-factory-130c70be.zip

cd crosshatch-qp1a.190711.019

fastboot flash bootloader bootloader-crosshatch-b1c1-0.2-5672671.img

fastboot reboot-bootloader

You should be able to do "fastboot flashall -w" after that.

Hi Chyifeng,

I am facing the same problem like above. I even tried to flash both partition using your steps and then flash the new build, hit the same issue. Please check if my sequence of steps are incorrect.

repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r2

repo sync -j80 -c --no-clone-bundle --no-tags

curl --output - https://dl.google.com/dl/android/aosp/google_devices-crosshatch-qp1a.190711.020-861edfad.tgz | tar -xzvf -

tail -n +315 extract-google_devices-crosshatch.sh | tar -zxvf -

curl --output - https://dl.google.com/dl/android/aosp/qcom-crosshatch-qp1a.190711.020-f44a22d8.tgz | tar -xzvf -

tail -n +315 extract-qcom-crosshatch.sh | tar -xzvf -

source build/envsetup.sh

lunch 14 //crosshatch

make -j80; mkdir dist; make -j80 dist DIST_DIR=dist

copy and unzip aosp_crosshatch-img-eng.subani.zip

fastboot -w flashall

Thank you for your help.

I am not sure what was wrong with your case. If you have successfully upgraded bootloader, you should see bootloader version

You can see the device rebooted once during flashing. In addition, you don't need to do " mkdir dist; make -j80 dist DIST_DIR=dist" since it fastboot should be able to locate out/target/product/crosshatch/ for new build image files.

Mine freezes after rebooting to fastbootd. it hangs on waiting for device.

Doing on pixelbook with linux apps. everything up to date.
