Boot Issue - AOSP image in db845

Hi, I am trying to boot an AOSP image on the dragonboard 845c.
I have followed the guide from the wiki (AOSP/db845c - Linaro Wiki ).

First, I downloaded the android.13 AOSP source tree and completed the compilation based on above link.
The flashing procedure is completed successfully in fastboot mode.

But the device is continuously rebooting. I have captured the log from minicom.
if anyone faced same issue before, please help me.
I tried to follow below link for recovery, but it’s not working, DragonBoard 845c Board Recovery - 96Boards
