Ok, I'm waiting

Are you sure about the resolution? 640 x 480 x 2 is only 612KB which the mp900/c having double that amount. Where are you seeing the resolution? Looking at the picture it seems higher.

Yes, I'm sure it's VGA. I got it from driver values in CE registry, WrTools ResInfo, own made screenshots, official specification.

It looks like higher res because whole system is modified - all elements are bigger than usual WinCE ones.

And it's 16, not 2 bit

Here you have sample screenshot: http://pdasite.pl/kitor/pliki/bsquare/p ... czenie.jpg

Hmm thats very strange. Maybe its an offset instead. That the starting area is higher than the mobilepro 900/c. Well, most likely not. hmm

Oh the 2 symbolizes 2byte not bit. 16bit = 2 byte. Well, I will build a kernel and start from there.

From WinCE registry (don't know what that numbers mean... but may be useful):

MediaPlug dword:0x0c00100
MemBase dword:0x0C200000
RegBase dword:0xc000000

very useful actually. It doesnt tell me the size but atleast says that the fb_starting point is correct.
you dont happen to find something called fbsize/fblength or similiar? Or videomemory?

No. Rest of keys are

Height: 480
Width: 640
Bpp: 16
Rotation: 0
RefreshRate: 59

I know why MP900c may have bigger display memory - it has got VGA port with output possiblity 800x600px.

Its an 2.6.29 image. Ive adjusted the framebuffer size. Please note that Ive had reports from mp900c users that they dont see anything (framebuffer doesnt work) but that may be specific to the mp900 since it uses seperate on/off features for their blanking (power off/on).

No video, after soft/hard reset blank screen, i had to disconnect battery.

I had the same issue when booting kernel from some fs loox, with display controlled by xscale.

Did you notice anything weird with the screen? I mean could you tell if the backlight acted differently? Like it stayd on when it usually goes off or the other way round?

That would indicate that its connected in the same way as the mp900/c and I need to add the proper blanking code

Maui has got only two backlight levels - full brightness and low, nothing between them. When I run kernel by haret, there's no framebuffer (everything hangs with wince with haret on lcd. Then if I press reset or do hard reset, device doesn't boot - blank display, no backlight, no keys/screen taps sound, only GSM led flashing as in normal work and charging led (if I connect power supply).

When using old kernel (this from photo), i can do soft/hard reset without problem

Oki might be due to blanking then, would explain why it doesnt work on mp900/c either. Will see if I can add that code later today.

Ok.

Oki, try it now. Ive added the blanking code (not clean but added).

Exactly the same problem I checked twice.

Maybe try with 2.6.24 kernel? (this is one that boots)
