S1D13505 Wind River WindML v2.0 Display Drivers
X23A-E-002-03 Issue Date: 01/04/06
Building a WindML v2.0 Display Driver
The following instructions produce a bootable disk that automatically starts the UGL demo
program. These instructions assume that Wind River’s Tornado platform is already
installed.
Note
For the example steps where the drive letter is given as “x:”. Substitute “x” with the
drive letter that your development environment is on.
1. Create a working directory and unzip the WindML display driver into it.
From a command prompt or GUI interface create a new directory (e.g. x:\13505).
Unzip the file 13505windml.zip to the newly created working directory. The files will
be unzipped to the directories “x:\13505\8bpp” and “x:\13505\16bpp”.
2. Configure for the target execution model.
This example build creates a VxWorks image that fits onto and boots from a single
floppy diskette. In order for the VxWorks image to fit on the disk certain modifica-
tions are required.
Replace the file “x:\Tornado\target\config\pcPentium\config.h” with the file
“x:\13505\8bpp\File\config.h” (or “x:\13505\16bpp\File\config.h”). The new config.h
file removes networking components and configures the build image for booting from
a floppy disk.
Note
Rather than simply replacing the original config.h file, rename it so the file can be kept
for reference purposes.
3. Build a boot ROM image.
From the Tornado tool bar, select Build -> Build Boot ROM. Select “pcPentium” as
the BSP and “bootrom_uncmp” as the image.
4. Create a bootable disk (in drive A:).
From a command prompt change to the directory “x:\Tornado\host\x86-win32\bin”
and run the batch file torvars.bat. Next, change to the directory “x:\Tornado\tar-
get\config\pcPentium” and type:
mkboot a: bootrom_uncmp
5. If necessary, generate a new mode0.h configuration file.
The file mode0.h contains the register values required to set the screen resolution, col-
or depth (bpp), display type, active display (LCD/CRT), rotation, etc. The mode0.h
file included with the drivers, may not contain applicable values and must be regener-
ated. The configuration program 13505CFG can be used to build a new mode0.h file.
If building for 8 bpp, place the new mode0.h file in the directory
“x:\13505\8bpp\File”. If building for 16 bpp, place the new mode0.h file in
“x:\13505\16bpp\File”.
