I have a 16 GB Jupiter 2 board (never factory flashed). The official documentation points to jupiter-bianbu-build, which only contains K1 firmware. The Ubuntu 26.04 images are not TitanFlasher packages. Which firmware ZIP should be used to perform the initial flash of a blank Jupiter 2? I’ve tried so many things at this point. I have the board visible via lsusb, titanflasher can see it, downloaded the bianbu image (and tried the ubuntu images for k3 - they seem to lack the firmware stuff). My last session was this:

Any pointers to which image I should use or what I’m doing wrong? Also tried booting off a .img written to a USB key, no luck.
