This 2025 device is using linux kernel 4.19.111 which was released in 2020. Update to 4.19.332 would be welcome. I don't expect anything more as i know Rockchip is the worst when they control so much of low level firmware. This is also running ancient version of U-Boot 2017.09-gfd8bfa2acd-dirty, buildroot 2018.02-rc3-ga77590f2, nginx 1.26.2, dropbear v2019.78, tailscale (but that can be updated with a script). I bought it for it to be connected to internet 24/7 but with software this old i can't trust it even a little.
