Relationship between battdrvr and pm

Hi All
What is the relation ship between power manager and battery driver? How the
power manager accesses battery functions. I use sample battery driver
supplied with wince 5.0 and unmodified pm code with smdk2440. I get following
prefetch abort exception while booting the system

the power manager calls GetSystemPowerStatusEx2 API (in coredll) to gain
battery information.
the API basically performs a DeviceIoControl with
IOCTL_BATTERY_GETSYSTEMPOWERSTATUSEX2
to the battery driver

Prefetch abort, that means the the CPU ran out of instructions to run.
Possible causes include:

1. System bus unavalable to read the next instruction
2. NULL function pointer being dereferenced
3. Corrupt stack
4. Corrupt RAM

Dear Bruce

I actually forgot to paste exception error and tell that I have no debug
support. I couldnt understand that by adding battdrvr, how a prefetch abort
occur in pm.dll? kindly suggest something.

Prefetch Abort: Thread=8ff93d48 Proc=8de4bd30 'device.exe'
AKY=00000009 PC=00000000(???+0x00000000) RA=03f31e9c(pm.dll+0x00011e9c)
BVA=00000000 FSR=00000005

Thanks

Sohail

Hey,
I sould suugest you write a small program that calls
"GetSystemPowerStatusEx2 ", see if this happen again.

I believe the exception happens in your battery driver, when trying to
read from HW. How do you have the battery connected to your
platform ?

Hi Warni

I am trying to use the sample driver for the time being (actually the battery
is sharing ADC of S3C2440 with touch screen) so no hardware interaction is
taking place. And I have tried to call GetSystemPowerStatusEx2, but it is not
included in coredll. I think there is a library linking problem (and I am
loading the driver as a dll). Honestly I couldnt understand the battery
driver architecture. In docs, the coredll module is battdrvr.lib while in
sample driver, it is battdrvr_lib.lib, what is this? can anyone explain?
It will be highly appreciated that some provide a step by step guide to
integrate the sample driver.

Best regards
Sohail

You must include battery support from the catalog and redo the sysgen. That
will bring in the GetSystemPowerStatusEx2 call.

Hi Luca,

Do you know any sample of how to do a basic DeviceIoControl with
IOCTL_BATTERY_GETSYSTEMPOWERSTATUSEX2 in C#

I have been stuck all week :(

Please help me, thanks
Marina

Hi Marina
In C# you dont need to do a DeviceIoControl, instead import coredll.dll and
call GetSystemPowerStatusEx2 function. this will give you the power status of
your system.

Hi sohailto,

thank you for replying... GetSystemPowerStatusEx2 looks good but this is for
Windows Operating systems not CE (sorry for posting this in the wrong forum)
but i need to be able to use DeviceIoControl but i dont know how this is done?

Or can i use GetSystemPowerStatusEx2 without CE ?

thanks

Hi Marina
GetSystemPowerStatusEx2 is indeed for Windows CE. But I am confused by your
last sentence "can i use GetSystemPowerStatusEx2 without CE ?" , what do you
mean by "without CE"? Using DeviceIOCtl from applications is not a good idea.

Thanks again, i need to get laptop battery information such as the battery
name and chemistry using DeviceIoControl (cannot use WMI)and I think I have
to use IOCTL_BATTERY_QUERY_INFORMATION ???

http://msdn.microsoft.com/en-us/library/aa372698(VS.85).aspx

Trying to use that from C# but i dont know how to :(

This is a Windows CE newsgroup. You might try asking in a relevent group
instead.
