Displaying 2 logos in bootloader?

Hi Experts,

I have a OMAP3530 based board with WinCE/BSP ARM_A8.

At startup, I would like to display 2 different bitmaps stored in NAND, one after another.  I add a call to BLShowLogo() in main.c of the eboot.  Both bitmaps are displayed OK except that there is too much flickering during the transition from the first screen to the second.

Would you please give me some tips on how to minimizing the flickering?

Thanks,

Luan
