@graysky, why do you keep mkinitcpio then as a dependency at all?

I think users wanting a rootfs on external media need it. Digging into other use cases for it. Reality is that having it generated only take 10-12 seconds, the file itself is only 8M, and it is harmless to have.

After upgrading to linux-rpi 6.3 the initramfs is not generated by mkinitcpio.

$this->bbcode_second_pass_code('', '
~ sudo mkinitcpio -p linux-rpi
==> Building image from preset: /etc/mkinitcpio.d/linux-rpi.preset: 'default'
==> WARNING: No kernel version specified. Skipping image 'default'
')

The option ALL_kver is empty in the package-provided /etc/mkinitcpio.d/linux-rpi.preset. (It wasn't empty in linux-rpi-6.2.12-1)
$this->bbcode_second_pass_code('', '
~ grep ALL_kver /etc/mkinitcpio.d/linux-rpi.preset
ALL_kver=""
')

Setting it to the below solves the issue.
$this->bbcode_second_pass_code('', '
~ grep ALL_kver /etc/mkinitcpio.d/linux-rpi.preset
ALL_kver="6.3.1-1-rpi-ARCH"
')

See this announcment: viewtopic.php?f=3&t=16144&p=71168#p71168

I do not believe my kernel will work with models older than RPi4/400.

Out of curiosity, is this necessary or what’s the advantage of this limitation?

I updated my RPi 4B using the instructions. The kernel loads but immediately after the screenshot below (apologies for the poor quality, it's a screenshot of a slow motion video) I'm left with a black screen--the monitor receives no signal. I'm booting from a USB to mSATA adapter. Ethernet cable is plugged in but no network (can't ssh, can't ping, doesn't show up in my router). It's not completely locked up though; num lock responds and the network adapter lights respond to a cable being plugged in/out but don't show any activity. I can ctrl-alt-delete to reboot. Any suggestions would be appreciated.

Your jpg is broken. Does systemd initialize? Any output there? Can you boot and run the repo linux-rpi kernel without errors? If so, the cause of your issue is likely with upstream code. You can open an issue if so but you will need journactl output or some boot errors to help.

I attached the SDD to another computer to search for journalctl logs and got nothing. I'm not a systemd expert by any means, but I looked in the places google suggested and didn't find anything. I also searched for any file modified recently after the previous boot and got nothing.

Here's a better screenshot and a video of what I'm getting. Screenshot shows the last thing I see before the screen goes black.
