k70 lcdc Controller; How to fill Background Look-Up Table

I will use the K70 LCDC Controller with an 8bpp Picture. In this case i must fill the internal Look-Up Table for the Background Picture.

I try this with the following code:

 

volatile uint_32 *LUT_BG; // Pointer Look-Up Table

LUT_BG = (unit_32*) 0x400B6800; // Adresse of the first Entry

*LUT_BR++ = color_1;

.....

 

My Problem is, i see no changes in the RAM. It seems that this area is write-protected.

 

Thanks,

Kai
