There isn't any hypervisor running on that and still no SVE

The number of boards supported by these two distros is astonishing:

The NanoPC-T6 is already supported by Armbian build system:

It's my understanding that https://www.armbian.com/ has quite broad hardware support, and there are boards from Orange Pi and Pine64 that boast actual mainline kernel support, so this is more a case of a fragmented ecosystem than there being zero competitors that can meet or exceed pis.

The normal Raspberry Pi OS Lite is pretty okay.

https://www.armbian.com/ is also pretty awesome and also supports bunch of other RaspberryPi clones for cheaper price.

git clone https://github.com/armbian/build cd build ./compile.sh BOARD=orangepi5-plus RELEASE=jammy BUILD_MINIMAL=yes KERNEL_GIT=full BUILD_DESKTOP=no BUILD_ONLY="u-boot,kernel,armbian-config,armbian-zsh,bootstrap" KERNEL_CONFIGURE=no

If the SBC is supported by Armbian then the software support is usually pretty good.

I use an old Android media player, repurposed with Ubuntu OS instead of Android (https://www.armbian.com/). Works fine, cost me nothing ($40 originally AFAIK, but it was being retired anyway). It has low power consumption, good reliability, more-than-adequate performance for HA and Plex media server. Equipped with multiple USB ports, ethernet, WiFi, HDMI.

The first thing you want to do is to get a JTAG adapter (I use ft2232h based board) and familiarize yourself with openocd. I have a tutorial on setting up openocd with ARM based chip. Then, you should get familiar with linker scripts.

Here's a repo I've made for my students https://gitlab.com/matsievskiysv/stm32_programming/. In it I start with assembly, introduce C and linker scripts and finally write my own HAL. It uses stock gcc, gdb and openocd from debian repo.
