I can find downloads for the Rockchip upgrade_tool for x86 Windows, macOS, and x86 Linux - could anyone point me at an ARM version of this utility so that I can update one Blade3 from another?
If a Gentoo ebuild of rkdeveloptool would be useful for anyone, I’ve created one here: Add dev-embedded/rkdeveloptool-1.32, update README.md · srcshelton/gentoo-ebuilds@490fab1 · GitHub
