BSP v5.1.0 does not start (for H3ULCB)

Hi,

I'm using the H3 Starter Kit.
(RTP0RC77951SKBX010SA03, S/N 25375, DDR 8GiB, Dual Rank)

I am trying to move the board according to the contents of the URL below (network boot):
R-Car/Boards/Yocto-Gen3/v5.1.0 - eLinux.org

However, the image and device tree transfer is successful, but the kernel does not work.
Is there a problem with BSP v5.1.0?
Do you have a track record of working with this board?

Thanks & Regards,
