Hi do minh quoc,

First create the 16bpp raw image data using "bmpToRaster" utility present int tools folder of starterware package. LCD controller needs to be configured for 16bpp this is done by inovinking RasterModeConfig(SOC_LCDC_0_REGS, RASTER_DISPLAY_MODE_TFT, RASTER_PALETTE_DATA, RASTER_COLOR, RASTER_RIGHT_ALIGNED); API with specified parameters. Also please refer to the 3.1.1 section of errat http://www.ti.com/lit/er/sprz360c/sprz360c.pdf for 16bpp connections.

Hi Savinay:

Now I also had a problem about it. My board is using 16bpp,

Picture can be loaded , but the color is not correct, I think some registers' configuration still are not correct

The link you gave above http://www.ti.com/lit/er/sprz360c/sprz360c.pdf is not available now.

Can you give some advice about how to configure for 16bpp(5:6:5) module in the Uboot. TKS

Alex,

The errata document you're looking for is located at the link below. As mentioned above, review Section 3.1.1 regarding color assignments of the LCD data signals.
