Today was a holiday, so family obligations didn't allow much time to
look at this.
I did however do a quick build with some printk's in
omapfb_setup_plane() so I could narrow down where to start looking.
I discovered that the error (omapdss OVERLAY error: check_overlay:
paddr cannot be 0) is happening as a result of the
ovl->set_overlay_info() call in the else clause of the code below:
if (pi->enabled) {
r = omapfb_setup_overlay(fbi, ovl, pi->pos_x, pi->pos_y,
pi->out_width, pi->out_height);
if (r) {
printk("omapfb_setup_plane: pi->enabled &
omapfb_setup_overlay()\n");
goto undo;
}
} else {
struct omap_overlay_info info;
ovl->get_overlay_info(ovl, &info);
info.pos_x = pi->pos_x;
info.pos_y = pi->pos_y;
info.out_width = pi->out_width;
info.out_height = pi->out_height;
r = ovl->set_overlay_info(ovl, &info);
if (r) {
printk("omapfb_setup_plane: !pi->enabled &
ovl->set_overlay_info failed\n");
goto undo;
}
}
I'll look at this more over as I get time over the coming days.

The only downloadable rootfs I have is 3.5 based. I'll try to get a
3.6 image posted in the next couple of days.

OK, will do that with my next build. I'll assume you want dss
debugging enabled for that.
