Hi Renjith, I don't know the answer to your problem but I would guess one of the drivers that your bus driver is enumerating is bad. So you need to isolate which driver it is.
I asked our drivers dev lead Kurt Kennett to help, and his response was:
From: Kurt Kennett
To: Sue Loh (DEY)
I’m a bit confused by his post. He says:
Once the bootup is done I am not able to execute any applications like
explorer.exe, ceplayer.exe, or not even a simple helloworld.exe. When I run
"gi proc" the output is like given below.
…
Then he says:
I did some trial and error and found out that when I disable busEnum.dll it
start working fine. I can run any application. The "gi proc" output also
became proper as given below.
…
Then he says:
And one more thing, when I run any application, the kernel and drivers work
fine. I verified this by enabling the touch panel debugmsgs for printing the
co-ordinates when I touch. I am getting all the prints properly. I also tried
by disabling touch driver and spi driver. But all the results were same.
Ok, so what I’m confused by – if he’s not loading drivers his touch wouldn’t work (I don’t think) if it’s mounted on top of SPI.
My advice to him at this point is to start with busenum.dll still ‘enabled’ (he should remove all the busenum stuff from his platform.reg), but with no drivers. If the platform boots and he can run apps, then it’s one of his drivers that is the source of his problem. If it still doesn’t work, then it’s something else.
The number of ‘udevice.exe’ is not something he should worry about – it’s a user-mode driver host. The ‘services’ stuff can load a user-mode driver, which will load into a udevice.exe.
