No green light, no display after flashing AOSP 13

I have built the latest master branch of AOSP and another branch for hikey, and I encountered the same unusual behavior on both occasions. After flashing the build using the “device/linaro/hikey/installer/hikey960/flash-all.sh” script and switching to the NORMAL boot mode, I noticed that the green LED, which normally pulses during boot-up (as seen in AOSP with Android 10), does not light up. Initially, I thought the device was not running, but I was able to access it using ADB shell.

I’m wondering why the board’s green LED does not light up as usual and why the display does not show anything. It’s worth noting that this issue occurs with AOSP 13 (current master branch), while it works perfectly fine with AOSP 10 in the exact same setup.

I would greatly appreciate any insights or suggestions regarding this matter. Thank you for your assistance.
