I am a software engineer. My current Project is I.Mx51 based on wince6.0.I  want to let IPU output digital video of bt.656 format when eboot is runing.  The format of  video is digital RGB565 before.
 I configure BSP like this:
1. \WINCE600\PLATFORM\iMX51-EVK\SRC\BOOTLOADER\DISPLAY\panel.h
    struct PANEL_INFO,modify IPU_PIX_FMT_RGB565 as IPU_PIX_FMT_YUV422
2.\WINCE600\PLATFORM\iMX51-EVK\SRC\BOOTLOADER\DISPLAY\ebootdisplay.c
  in function CPMEMSetup ,modify CPMEMData.iPixelFormat=CPMEM_PFS_INTERLEAVED_RGB
as  CPMEMData.iPixelFormat=CPMEM_PFS_NON_INTERLEAVED_YUV422
  someone tell me,if successfully,I can get data output from IPU only pin0--pin7,and other pins is no data output .But I get data output from IPU pin0--pin15. The result is the same as digital RGB565 output.
  who can tell me why I fail,and how to configure bsp.
