it is a SoC from xilinx with 2 arm cortex a53 kernel on it
This is an ultrascale? I’ve run the current ipipe code (4.19) on the
ultra96 without issue.
You are right. It is a Xilinx UltraScale+ ZU2CG. For some reasons we
need the 5.4 kernel version on this board.
In the CIP project, Cybertrust is currently working on a mainline
backport of UltraScale patches to 4.19-cip. I have no overview about
what they already support or can realistically achieve, but it may be a
plan B. If there is interest, I can ask them for an update on the
current status.
