Hello Jay, welcome!<br>
Let me see if I can address your questions together.
and a bit out of <br>
order. If your idea is to use Fedora userland, then
I'd use fedora <br>
altogether, they don't have rpi4 specific builds, but
they don't need it <br>
either. Fedora uses always the latest mainline kernel,
and it has "good <br>
enough" support for what you're trying to do
(basically headless). If <br>
you were trying to do something with graphics, it
would be a completely <br>
different story.<br>
If you decide to use CentOS, I'd not use the armv7hl
image (32 bits) and <br>
go straight to aarch64. There's no official image yet,
but I've posted <br>
one that is working really well <br>

moz-do-not-send="true">https://people.centos.org/pgreco/CentOS-Userland-8-stream-aarch64-RaspberryPI-Minimal-4/</a>
<br>
, and this is where I keep the updated kernels <br>

(along with other <br>
rpi-specific stuff)<br>

<div><span>Thank you for replying so promptly, Pablo! I actually
tried to get Fedora to run from a USB attached HDD, but my
knowledge was not good enough. I can only get it to boot
from sd card. Thats why I love the way CentOS boots with the
rpi4 image: I just have to point root to sda3 instead of
mmcblk0p3 in cmdline.txt (tried to use partuuid, which works
for booting, but then the script rootfs-expand does not find
its expected rootfs). <br>

Wrt Fedora boot, if usb works after you boot from the SD card, then
I guess I'd check 3 things, rpi-eeprom (needs to be rather new to
support booting from usb), rpi-firwmare (rpi-specific files in
/boot, also need to be rather new), and maybe, but less likely,
driver missing in the initramfs. Wrt cmdline.txt and UUID, I have no
idea why that doesn't work, I too change it to /dev/sda3)<br>

<div><span>So today I tried the centos image you mentioned (8,
stream, aarch64). It works just fine, however the cpu
frequency stays at max. With the centos 7, armhfp image the
cpu is allowed to throttle down. Is that a kernel or config
thing? I have only tried compiling armhfp kernels from the
raspberry github. I can try to compile a 64bit one if they
have the correct sources and configs. Anything more than
that exceeds my current abilities. Can you point me in a
direction (like where to look for the cpu frequency issue)?

I guess something tuned is doing, or something missing in the
config.txt. The kernels are the ones from the rpi foundation's
github, but just rebuilt for CentOS with a few different options.<br>
