Pixel 4 with libfuzzer from master branch got struck at google logo, not booting.

[manika...@gmail.com]

Hi,

I followed the steps from https://source.android.com/devices/tech/debug/libfuzzer, and build for Pixel 4

#repo init -u https://android.googlesource.com/platform/manifest -b master
#repo sync -c -j8

#sh extract-google_devices-flame.sh

#sh extract-qcom-flame.sh

#source build/envsetup.sh

#lunch aosp_flame-userdebug

# m RELAX_USES_LIBRARY_CHECK=true

Then I flashed using #fastboot flashall

Device got struck at Google logo, Could you please suggest any other way or how to resolve it.

Thanks

Sai

I accidentally replied directly, so thought I'd copy the contents of the message here for posterity:

---------------

It's possible you might have synced to a bad (broken) build revision, or you're using the wrong binary blobs. I notice that the Driver Binaries linked to in the Android fuzzing documentation are for Android 11, whereas AOSP is currently building for Android 12/13, and you probably need the beta drivers.

As a side note, you might find flash.android.com useful, as flashing your device from source manually isn't necessary for fuzzing. Best bet is to flash the latest aosp_$DEVICE_hwasan-userdebug from the aosp-master-with-phones-throttled branch.
