Re: Windows CE - CEPC Display Problems

Hi,

It appears you have more than 1 problem with your image. If you say you
can't manuver the menu's, do you mean that the mouse isn't working?

It is very normal that the display driver uses it's default resolution of
320 x 240 (QVGA) if you choose an invalid video mode. loadcepc.exe checks if
the suggested mode is possible with your adapter, and doesn't transfer any
video mode parameters to the CE image when the settings are invalid. At that
moment, the video driver of the CE image will switch to it's default
resolution, the same as if you started loadcepc without the /L:800x600x16
option.

How did you capture the debug output? Do you have a serial (null modem)
cable connected from your target pc to your development pc? Do you see debug
output from the image if it comes up in it's default 320 x 240 resolution?

What design template did you choose to build your image? Some catalog items
can be missing, so that your pointing device doesn't work. Is it a USB
device or is it connected on the PS/2 connector? If it is USB, it is almost
sure you have to add USB Host driver and HID driver to your design.

What kind of video card or chip is there in your target pc? Maybe some
people reading this newsgroup had similiar problems with that specific
chipset or adapter.

I think the first step to go, is trying to capture the debug output of your
image. This will probably give you some information why the video driver
won't start. You also have to make sure that the video adapter has enough
video memory available for the higher resolution. I had to put it to 4Mb to
use a 800 x 600 x 16 resolution.

It's best to work on just one problem and resolve it, before you start with
the next.

Don't think that creating a CE image is a job of clicking a couple of item's
in platform builder. It can take days to resolve the last minor problems of
a new system board. If you don't have this time, or don't want to do the
effort, it is better to choose a board which comes with a BSP for windows
CE. With these boards, the hard work is done for you.

The platform builder help tutorials are a very helpfull tool to clear things
up.

Regards,

Luc

I'm trying to determine if developing my industrial PC using WinCE is
possible. I've downloaded the WinCE500 demo version and I've done the
following (with only slight variations):

* Made a simple CEPC OS design with the Display Driver: VGA Linear
(flat) Framebuffer
* Made a bootdisk using CEPCBoot.144
* Ran vesatest.exe to find valid run modes (800x600x16)
* Ran "LOADCEPC /V /E:0:0: /L:800x600x8 eboot.bin"
* Successfully uploaded the NK.BIN from my development computer.

When I do this, the Target's display goes black and the debug
information stops being sent. I've tried it in different modes and
only one works: On the config.sys bootmenu, I've selected the
640x480x32, an invalid mode for my target. When I run it like this, I
get the same results as when I run "LOADCEPC /V /E:0:0: /D:0 eboot.bin"
The target screen is in 320x200 and I can't manuver the menus to
continue.

Can anyone suggest anything I should try?
