Pixel 2 device hanged on boot up after flashing the kernel downloaded from repo android-msm-wahoo-4.4-pie-qpr2

[sachin verma]

Hi Everybody,

I have compiled android kernel source for Pixel 2 device from latest repo branch android-msm-wahoo-4.4-pie-qpr2 given on developer site. I followed the steps mentioned there(developer.android.com) and also generate new boot.img by running command m bootimage from AOSP10 root directory after setting TARGET_PREBUILT_KERNEL path.

Then flashed the new image, flashing was successful but the device is not booting up and stuck on android logo.

It seems kernel repo is not updated for AOSP10(Q) and existing repo branch android-msm-wahoo-4.4-pie-qpr2 is for only AOSP9(pie).

I need Pixel 2's latest repo for kernel which runs with AOSP10. Could you please let me know the latest repo branch for kernel source code for android Q.

Note: adb is in disconnected state during hang issue, so unable to capture the logs.

Thanks,

Sachin

I also tried to perform repo init with branch  android-msm-wahoo-4.4-android10 for AOSP10 kernel but could not succeeded.

repo init -u https://android.googlesource.com/kernel/manifest -b android-msm-wahoo-4.4-android10

Below is the error:

Please suggest the correct repo branch to sync the kernel code.
