I am developing auido driver in wince 5.0, and use MDD/PDD model, when i use
"software mixer", there is such error.
1. When I play audio files which is located in release directory,such as
"close.wav", and the debug message shows:

I am implementing an audio driver for WM 6.0.
Should I assume that an execution of WAV_IOControl() called by one
thread can be overwrapped by another execution of WAV_IOControl()
called by other thread?

I know that there is a limit of 512 MB RAM under windows CE 5.0. I
would like to know if that limit still exist under WinCE 6.0.
If the answer is yes, then I would like to know which mechanisms I
could use to overcome this limitation. I read in another thread a post

In CE 6.0 the OEM_CERTIFY_RUN is not longer supported, so the OS either
loads the module or not. However, in the documentation there is still a
list of privileged (formerly called trusted) APIs. In CE 5.0 these APIs
were not accessible to applications with the OEM_CERTIFY_RUN.

Any issues with PB 5 and Vista.
I'm thinking about rebuilding my dev PC and making the move to Vista.

I have a problem in starting the kernel debugger from platform builder
4.2. I am using the ethernet for downloading and kernel transport. My
PC is running windows xp professional, and the target is running wince
4.2.

I have a performance problem in Eboot. I try to implement a decompression
(based on LZMA). The same code runs about 6 times faster in Windows CE 6
with the same hardware (custom system with pxa270). I check everything I
think of: instruction cache and data cache are enabled; CPU ...

Does anyone know of an existing SD host controller driver for the OMAP
2420/2430?  I'm specifically looking for one that supports SDIO and not
just SD memory cards.

this please reply...
Shall i develop it as a stream interface driver?

I have an HP iPAQ 2490 PPC (WM5.0). I want to use it as a USB removable
drive, for transferring files to PCs without ActiveSync installed.
I guess 'usbmsfn.dll' contains the USB BOT transport 'bot.cpp'
and the SCSI-2 emulator 'block.cpp' and the DLL could meet my need

Dear Greats,
We are using dual I2C Philips UART with single interrupt line source.
We have implemented ISR that reads the Interrupt Status Register
through I2C communication and resolves the proper UART1/UART2 logical

I use RegisterDevice and DeregisterDevice for a bluetooth dongle.
When my application starts i call RegisterDevice and if the return
value is not NULL I will proceed with the CreateFile for the serial
port.

Hi Valter,
unfortunately I cannot tell you a good technical reason to use more
than the 512 MB of DRAM. It is basically a costumer's requeriment
because he will use our board to run simultaneally several applications

I need all information about the function
VOID WRITE_PORT_UCHAR(PUCHAR Port, UCHAR Value )I looked in the "Platform
Builder Help Files" and got a few questions:
What exactly means "mapped memory range in I/O space"?

Hi Platform builder developers,
until now I only used Platform Builder 5.0 to build my Windows CE device
(all ARM based).
I need now to build a Windows Mobile 5.0 device (with the same hardware,
