    The BitmapBoot-Tool is used to create a splash-screen which is shown during device start.

    The Windows CE OS-image can take the display-parameters from this splash-screen. This allows an easy change of the display, without the need to modify the Windows CE OS-image.

    For Trizeps6 you do not need the BitmapBoot-Tool ( see Boot-Bitmap ( Trizeps VI)).

    Creation of a Bootlogo

    To create your own bootlogo, create a bitmap with 8Bpp color-depth. This picture must have a smaller or same resolution, than the display-size specified in the Display Definition File: eg. for tr4_svga 800×600; for tr4_vga 640×480.

    open a cmd-line ( Start→Run or Start→Ausfuehren: cmd) on your Windows XP or Vista machine:

    bitmapboot *.dis <your bitmap> <output file of bitmapboot>

    i.e.:

    bitmapboot tr4_svga.dis kkbooting8.bmp kkboot.tft

    Put kkboot.tft on a SD-Card and enter the bootloader. On your Hyperterminal command-prompt enter:

    boot mmc kkboot.tft

    The picture is shown and you're asked if you want to save the picture.

    Note: If the picture-size has changed from the previous-bootlogo, you must reinstall your Windows Embedded CE-Image.

    BootBitmap CmdLine-Options

    DisplayDefinitionFile:

    describes display-parameters.

    BitmapFile:

    any 256 color bitmap file (*.bmp) which fits to the display.

    BootableOutputFile

    the output file which can be booted by bootloader.

    Options

    These options may be used:

    • show_continue → shows the bootlogo and continues without storing it to flash.

    • burn_continue → stores the bootlogo to flash without showing it.

    • show_stop → shows the bootlogo without storing it to flash and halts the bootloader if a autoboot.00x -sequence is used.

    On default, the bootlogo is shown and the user is asked through the bootloader-interpreter, if it should be stored to flash.

    Display Definition File

    The Display Definition File typically has the extension .dis and contains the display-parameters.
    It is the same for Trizep2, Trizeps3 and Trizeps4.
    Trizeps5 has some differences.

    Field

    Description

    Field

    Description

    Paramcnt

    Number of parameters. Currently fixed to 16 (0x10)

    FBADR

    FrameBuffer-address. This is the address, where the DMA-descriptors and the framebuffer of the picture will be put. When using Windows CE as OS, use 0x80088000 for Trizeps5 and 0xA0088000 for all other Trizeps.

    Bpp

    Bits-Per-Pixel. The bootloader always uses 8Bpp. You may use either 8 or 16(0x10). When using 16, it will be used by Windows CE

    Use16BitPalette

    set to 1

    CxScreen

    Horizontal resolution of the display

    CyScreen

    Vertical resolution of the display

    Control0

    == LCCR0. See PXA2xx Developers Manual for details.

    Control1

    == LCCR1. See PXA2xx Developers Manual for details. The last 10 bit contains the horizontal resolution of the display. Leave it 0, because it is calculated from CxScreen

    Control2

    == LCCR2. See PXA2xx Developers Manual for details. The last 10 bit contains the veritcal resolution of the display. Leave it 0, because it is calculated from CyScreen

    Control3

    == LCCR3. See PXA2xx Developers Manual for details.

    DataBits

    set to 0x10

    DisplayOn

    Brightness

    Default brightness-value to use.

    Contrast

    Default contrast-value to use.

    Feature

    UseEDTSSP

    Used for special smart-displays, which need additional initialization. i.e. through i2c or SPI

    DisplayName

    Name of the display

    Please note, that the order of the fields must be kept.
    The field-name before the value is not interpreted by bitmapboot.
    Features and options might be different on different Trizeps-modules; i.e. PWM is only supported for special pins.

    Trizeps and Trizeps5 Differences

    To port a .dis-file from Trizeps to Trizeps5, you need to modify following entries:

    • FBADR: Change from 0xa0088000 to 0x80088000.

    • Bufferstrength for Trizeps5 is set throug HAL reading MFPR Registry values

    • Control3: Change the least-significant-byte (LSB) of Control3 (Pixel-Clock-Divider).

    The lcd-controller-clock-frequency is twice as big, as on the other Trizeps-modules (e.g. 208MHz instead of 104MHz).

    On Trizeps:
    Pixel-Clock-Frequency = 104MHz/(2*(PCDtr4+1))
    On Trizeps5:
    Pixel-Clock-Frequency = 208MHz/(2*(PCDtr5+1))
    So you have to recalculate the Trizeps5-Pixel-Clock-Divider to be:
    PCDtr5 = (2*(PCDtr4+1))-1
