Building a WindML v2.0 Display Driver

Note
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.
1. Create a working directory and unzip the WindML display driver into it.
2. Configure for the target execution model.
3. Build a boot ROM image.
4. Create a bootable disk (in drive A:).
5. If necessary, generate a new mode0.h configuration file.
For the example steps where the drive letter is given as “x:”. Substitute “x” with the
drive letter that your development environment is on.
Rather than simply replacing the original config.h file, rename it so the file can be kept
for reference purposes.
From a command prompt or GUI interface create a new directory (e.g. x:\13705).
Unzip the file 13705windml.zip to the newly created working directory. The files will
be unzipped to the directory “x:\13705\8bpp”.
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:\13705\8bpp\File\config.h”. The new config.h file removes networking compo-
nents and configures the build image for booting from a floppy disk.
From the Tornado tool bar, select Build -> Build Boot ROM. Select “pcPentium” as
the BSP and “bootrom_uncmp” as the image.
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:
The file mode0.h contains the register values required to set the screen resolution, col-
or depth (bpp), display type (passive or active matrix), rotation, etc. The mode0.h file
included with the drivers, may not contain applicable values and must be regenerated.
The configuration program 13705CFG 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:\13705\8bpp\File”.
