Hi,
For GC+ below is the setting we used

For Linux, you also need either:
0xB0100010 0xFFFF1000; 8bpp
or
0xB0100010 0xFFFF2000; 16bpp
See topic 736 for further details. |

The LCD bpp is different from the framebuffer bpp. If your LCD has only 12bpp you should select 8bpp for the framebuffer, this will result in a 256 color palette (hence the 8bpp), each color in the palette will have 12bpp. |
