1. Try upgrading your GCC compiler to 4.3.2
2. To avoid Division in code: try using shift operation instead of div.
E.g. c = c x instead of c = c / x;

Hi Roman,
Please take care of the dma_sync_single If applicable.
My driver was not working till I made changes related to dma_sync_XXX.
See this message from Vineet Gupta query about dma_sync_*_for_cpu and

Hi All,
I am using Linux kernel 2.6.26.3 on ARM.
I have two Ethernet modules. Based on the hardware (run time) I have to
run specific driver. Checking hardware is easy, On run time I can read
the registers and will know which Ethernet Chip is present.
Individually both Ethernet driver
Hi All,
I am using 2.6.26.3 kernel on ARM922T.
Can any one help me understanding how to solve Exception stack occurring when
interrupt is triggered from the hardware. Here is the log given below.
Due to this problem interrupt is some how hangs some times and some times it
comes correctly.
If it is udev, how does it determine the major and minor number of
the
device?
From the dev file in the sys/class/... file for the device, or from
the uevent itself. newer versions of udev only use the uevent, and
don't need sysfs.
Just a small question, which newer version of kernel don't
Yes got it, thanks. Sorry it was a silly question.

Hi Vamsi,
For Otg perspective, you need to 1st implement USB Host, USB Gadget and
then USB OTG driver, by using Linux USB core.
About the Scenarios: when user want to use USB OTG, so at that time
Host, Gadget and otg (in same order) should be loaded into the kernel or
memory. So OTG can shift to
I am extremely sorry I mean 3rd Party USB Stack.

I think, try to see code of The USB Monitor specially file mon_main.c
Try to develop your own application driver, also enable /proc interface,
In case you want to check from command prompt about the status of usb
device like Memory stick connected to your linux usb host. Also user
space
We have implemented OTG in linux using the existing frame work as
suggested by Greg. But in our case we have take 3rd usb stack and done
the integration with Linux frame work. I think you can see
implementation done by omap guys for OTG.

You can have multiple kernel source code, then compile the code. But here you
will not able to test it. When compiling a module will get the local header and
etc...where ever your make file points.
Things to check here is
1. you want to try different compilers.
2. you want to try different
