Hi Laurent, I've had some interesting failures on the VSP1 tests on the M3-N board.

Please see the reference image and resulting output at: https://ibb.co/fjPpkK https://ibb.co/mfybXz I'm sure I haven't seen this issue on the H3, so this could be an M3-N specific issue. Oddly, a later test (25, which I've posted earlier today) fails, because the images are rotated 90* to the left ... So it seems like there is certainly some uninitialised or confused state on the ROT bits somehow. For reference, this is on my branch du/2018q3 on my rcar.git repo. Commit 889e6d80c9f0eef433cfa1828c9a9d32a78479c2 which is based upon your drm/du/next branch. -- Regards -- Kieran
