Porting M5rc14 To Real Hardware Options

[Mrflying]

Hi everyone:
Does anyone can help me? Thanks in advance.
I'm now working on porting m5rc14 to our platform.
I meet 2 problems:

1) when system starts, console seem almost hangs. and process
system_server
occupies 99% of CPU time.

This is my logcat:
W/AudioFlinger( 557): Using stubbed audio hardware. No sound will be
produced.

It seems services don't respond to SeviceManager, it doesn't happen on
previous version

2). There's nothing appear on the screen. (screen is turned to black,
it doesn't happen on previous version, too)

m3rc37 system runs well on our platform with new released kernel.

very much please to have even a partial version working!!!

You mean you don't even care that the screen is black all the time?
I've created an installable image from the new SDK. From what I see in the traces Android starts normally. It's just that there's nothing displayed...

if you tap around on the screen, can you tell if something's happening by looking at debug output and any processes/threads running?

Hi,

Have you got some IOCTL errors about /dev/fb or /dev/graphics in the debug output.
The last time i've got a black screen problem when porting an appli, it was because of the use of a double framebuffer.
The framebuffer was mmaped in ram with the size of two screens and it started with the second screen !!!
and then tried to switch the base address of the visible window with "FBIOPAN" IOCTL (don't work with our driver).
Maybe It's not our actual problem, but i have no other idea.

All of you make a great work about porting android !!!

I see no IOCTL errors of significance. All devices are created nicely when running the /init executable, including /dev/graphics/fb0. This is no double framebuffer as far as I can tell. All services start successfully (I don't see the errors as described in the first post).

The main difference between Qemu emulator and Zaurus seems to be the supported OpenGL options. From what I remember, the Zaurus doesn't support page flipping.

[Android Zaurus]

My guess for now. Let the Android use drivers/video/pxafb.c not platform driver in arch/arm/mach-pxa. I'm working on another project for now and my Zaurus is configured for m3 Android. Later I'd like to try to build the kernel with CONFIG_FB_PXA=m and see what happens.

By the way, I found this wiki is very informational.

Setting CONFIG_FB_PXA=m changes the behavior indeed... it turns the screen to white instead of black
To be precise, the screen is white all the time, not only when switching to graphics mode, but also at startup and in console.
So, this seems not to be the solution either.

Look at the interesting part (sorry, it's a bit long) in the trace output below. It says "page flipping not supported (yres_virtual=640, requested=1280". I think this is the problem we're facing.
