- **CHANGE**: This version tries to boot SD first (thus SD -> USB -> NVMe -> eMMC); before it would boot USB before SD - as Armbian u-boot is possibly deployed to SPI, try to make as compatible as possible; eg enable squashfs support - enable `setexpr` and `fileenv`, used by HAOS - HAOS already has support for booting VIM3 from NVMe: https://github.com/home-assistant/operating-system/pull/3784 - borrowed `fileenv` patch from v2025.01 to .04 - Similar treatment that `odroidm1` got in https://github.com/armbian/build/pull/7769 - note: I will be leaving my VIM3 behind in the other side of the globe, so this is my last chance to test
