how to add a logo from u-boot in am335x starter kit

Hi Biser,

I found the solution................here is the steps...........this is only for starter kit.............................

1. 下载starterware

2. Install it;

2. Go to instalation directory and find /tools/bmpToRaster;

3. Go to the header file BitmapReader.h and comment out #define COMPRESS.

4. To get the binary do make command;

5. Prepare the image with exactly size of display, in my case the image is horizontal with 480x272 pixels and 24bpp. The file name is image.bmp;

6. Put the image file on /tools;

7. give the command: ./a.out 480 272 ./imagem.bmp ./image.h 24 RGB;

8. The file image.h will be created;

9. Edit this file with this:

#ifndef CONFIG_SPL_BUILD
unsigned int const image1[] __attribute__((aligned(4)))= {

.... 
}
#endif

10. download the attached file . Copy /lcd directory to /u-boot/driver lcd.tar.gz

11. In /u-boot/Makefile add the red line:

LIBS  = post/libpost.o
LIBS  = drivers/lcd/liblcd.o 

ifeq ($(SOC),ti81xx)
LIBS  = $(CPUDIR)/omap-common/libomap-common.o
endif

12. At /uboot/include/configs/am335x_evm.h add the lines bellow just before the file end:


#define CONFIG_LCD_TCM  

13. At /u-boot/board/ti/am335x/board.c add the red line inside board_init(void):

...

#ifndef CONFIG_SPL_BUILD
    board_evm_init();

  Lcd_Init(); // Initialize
#endif

....

    gpmc_init();
