BredOS on a Radxa ROCK 5B arm device and running from a Samsung SSD 970 EVO Plus NVME. This is the fastest setup I have seen for an ARM device, and it is the most stable RADXA ROCK 5B operating system I have found.
Shout out to @Rippanda12 and the rest of the devs at BredOS.
This is the first ARM device I have seen that uses initramfs-linux and vmlinuz-linux files, but still uses a u-boot bootloader. At least that is what I believe is going on. I am in doubt so far how the boot system works.
