Building Image for Odroid C1 is broken again since some weeks (old u-boot compiler?).
I created above images with this help https://docs.armbian.com/Developer-Guide_Build-Preparation/
on Xubuntu 22.04.1 direct (no Virtualbox/Docker), just ./compile.sh and choose EOS odroidc1
but as it's broken, no need to download all dependencies.
Kernel can be upgraded with armbian-config (System, Other). 5.15.80 and 6.0.10 are latest, but you can install 6.1.0 from https://github.com/hzyitc/armbian-onecloud/releases , just download (eg. with wget to /tmp)
linux-dtb-edge-meson_23.02.0-trunk_armhf.deb
linux-headers-edge-meson_23.02.0-trunk_armhf.deb
linux-image-edge-meson_23.02.0-trunk_armhf.deb
and install all 3 packages with "dpkg -i linux*.deb" (takes some minutes) and reboot.
armbian-onecloud has S805 like Odroid C1.
