Somehow, my TFT hooked on VOUT[1] displays properly, with the right timings etc, but it appears that the R abd B channels are inverted. I tried to use 'fbset' to change that, but it doesn't seem to work at all.
Anyone has a way to invert these channels, or to make the fbset tool work ? It appears that the fb screen sits 'before' the display and gets converted in hardware to that RBG mode somehow...
