First; Congratulations to the team for releasing both the x64 and ARM versions! 
I noticed there’s only a initramfs-linux.img file in the /boot directory of the september-version in a fresh/new installation of EndeavourOS and no amd-ucode.img or intel-ucode.img anymore. Is this correct?
With kind regards,
Peter.
Welcome aboard!
Welcome to the community !
Thank you!
Thank you! Glad to be part of it!
Now as to your question. I found this: https://www.reddit.com/r/archlinux/comments/hdrron/amd_microcode_not_loading/
Did you update bios recently or build a new machine? How old is the system?
It’s a new laptop (the old one from 2009 broke down), an AMD Ryzen 7.
I tested it too with a new installation of the latest release of Manjaro and that distribution did install amd-ucode.img in the /boot directory.
Just wondering why EndeavourOS did not?
Thank you Joe!
Yes, I do know that specific grub-line. I have a multi-boot setup and always use an Arch-based distribution to update grub whenever there is a kernel-update in a not-Arch-based distribution. That way I know that special grub-line for Arch-based distributions stays correct.

Can you go back and edit that output with 3 ``` before and after the text? It is easier to read.
And pacman says it’s installed:
[peter@LLAMD ~]$ pacman -Ss microcode
core/amd-ucode 20200817.7a30af1-1 [installert]
Microcode update image for AMD CPUs
Should I then re-install it or do I get in trouble then? I know I have to re-install grub again after that
.
Do in terminal:
sudo pacman -Ql amd-ucode
amd-ucode /boot/
amd-ucode /boot/amd-ucode.img
amd-ucode /usr/
amd-ucode /usr/share/
amd-ucode /usr/share/licenses/
amd-ucode /usr/share/licenses/amd-ucode/
amd-ucode /usr/share/licenses/amd-ucode/LICENSE.amd-ucode
But I get this when listing the contents of /boot:
[peter@LLAMD ~]$ ls -lga /boot

Can you find where amd-ucode is located?
find / -name amd-ucode.img
First of all, Welcome! 
And thanks for the report!
We are investigating this and can confirm that the offline install seems to have this problem. We are fixing it as soon as possible.
Meanwhile, simply installing package amd-ucode and updating grub.cfg is the recommended workaround:
sudo pacman -S amd-ucode sudo grub-mkconfig -o /boot/grub/grub.cfg reboot
As a general rule, it is always recommended to make a backup of any personal data you might have on the machine before making any changes.
Also, the online install looks like not having this issue, so currently users are urged to make only online installs.
I tested it on my Ryzen 3800X which is a desktop with AMD RX590 Graphics.

Edit: I am running the Btrfs set up without luks on this one with snap shots using timeshift.
Thank you @manuel for your solution!
I indeed used the offline xfce installation.
Will apply your solution shortly and inform you about the result.
