U-Boot stuck at "Starting kernel ..."

When I compile U-Boot 2020.07, the boot process hangs at the “Starting kernel …” message. However, when using a precompiled U-Boot 2013.01, the kernel successfully starts.

All other parameters are the SAME between U-Boot versions (the DTB is the same, the kernel is the same, and the U-Boot configuration is the same).

Will you please provide me with guidance on what else to check? Thank you!
