Thanks for the great tutorial. I think I followed all steps precisely on a Raspberry Pi 5 using Raspberry Pi OS Lite (64 bit, 2024-11-19) and am experiencing issues during the first boot.
One place where I deviated from the instructions is the Kernel version. The base image I built upon is using: 6.6.51+rpt-rpi-2712. So when I built initramfs (staying with the 16k page size), I executed:
kversion="6.6.51+rpt-rpi-2712"
echo "CONFIG_RD_ZSTD=y" > /boot/config-$kversion
mkinitramfs -o /boot/initramfs_2712 $kversion
rm /boot/config-$kversion
(this worked without errors, just as a clarification where I deivated from the instructions).
So when I connect the RPI to ethernet, power up, nothing appears in the network. Unfortunately I don't have a screen at the place where I have ethernet connection. If I move the RPI to a screen, this happens:

Do you have any idea what's going wrong? Obviously it's not able to connect to the network at this point. But I'm also not able to enter anything via the keyboard.
