I actually reconsidered my investment in the Premier when I was about to pull the trigger and buy into SiFive to stick with the Jupiter2 when I saw the metal case, fan and heatsink—not mini-ITX, but I’ll go with Jupiter2 since Milk-V’s actually going all out for support this time in contrast to the first generation for a solid PC build.
I believe you were looking for documentation for Jupiter NX if my memory serves correct…. Did you manage to piece everything I posted under that thread?
Should’ve been much easier if you’re using Linux than it is for me since I’m building a custom Rust OS, but I’ve made some progress into the Jupiter NX’s architecture since then to find the Jupiter NX is more similar to the Jupiter ITX than I previously thought, and the Jetson Nano boards are nothing more than pass-through for Jupiter OS to have I/O to the Jupiter NX.
Should be more likely than not similar with Linux.
