The problem is of course the wrong usage of tilcdc_set() for the palette load mode bit-field in tilcdc_crtc_enable(). I'll change: tilcdc_set(dev, LCDC_RASTER_CTRL_REG, LCDC_PALETTE_LOAD_MODE(DATA_ONLY)); to tilcdc_write_mask(dev, LCDC_RASTER_CTRL_REG, LCDC_PALETTE_LOAD_MODE(DATA_ONLY), LCDC_PALETTE_LOAD_MODE_MASK); in tilcdc_crtc_enable(). That should fix the problem.
