Thanks for your report.

I looked over the log and maybe found the bug.

The root causes are

  • Rootfs couldn't find wl_output object with some reasons. wl_output object is for example, HDMI. So it maybe caused by contact failure between KF and your board.

  • Window Manager doesn't care if there is no output object, then access to null at line 208 in window_manager.cpp (output.front)

I could reproduce the issue without plugging HDMI.

On master, I refactored window manager to use ilmControl library then remove original source code.

So I'll backport the code on master to flounder to fix this issue.
