I had previously brought up openSUSE on the IFC6410. A week before Hackweek Interstellar I got the IFC6540 to boot on serial console using the upstream-based Linaro integration branch, up to searching for the rootfs. Since USB and SATA support were still missing, my goal will be to prepare a MicroSD based rootfs to complete the bringup.
Testing my xf86-video-freedreno package on this board would be the next step.
Packaging gcc cross-compilers for the Hexagon aDSP and investigating how to deploy such code would be another related topic.
This project is one of its kind!
